<p>The Nearctic bark beetle genus <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
</named-content>
</italic>
Geoffroy was revised based in part on a molecular and morphological phylogeny. Monophyly of the native species was tested using mitochondrial (COI) and nuclear (28S, CAD, ArgK) genes and 43 morphological characters in parsimony and Bayesian phylogenetic analyses. Parsimony analyses of molecular and combined datasets provided mixed results while Bayesian analysis recovered most nodes with posterior probabilities >90%. Native hardwood- and conifer-feeding <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
</named-content>
</italic>
species were recovered as paraphyletic. Native Nearctic species were recovered as paraphyletic with hardwood-feeding species sister to Palearctic hardwood-feeding species rather than to native conifer-feeding species. The Nearctic conifer-feeding species were monophyletic. Twenty-five species were recognized. Four new synonyms were discovered: <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>

Geoffroy was revised based in part on a molecular and morphological phylogeny. Monophyly of the native species was tested using mitochondrial (COI) and nuclear (28S, CAD, ArgK) genes and 43 morphological characters in parsimony and Bayesian phylogenetic analyses. Parsimony analyses of molecular and combined datasets provided mixed results while Bayesian analysis recovered most nodes with posterior probabilities >90%. Native hardwood- and conifer-feeding <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
</named-content>
</italic>
species were recovered as paraphyletic. Native Nearctic species were recovered as paraphyletic with hardwood-feeding species sister to Palearctic hardwood-feeding species rather than to native conifer-feeding species. The Nearctic conifer-feeding species were monophyletic. Twenty-five species were recognized. Four new synonyms were discovered: <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>

Geoffroy, 1762 species (<named-content content-type="taxon-name"><named-content content-type="family">Curculionidae</named-content>

). The <named-content content-type="taxon-name"><named-content content-type="subfamily">Scolytinae</named-content>
</named-content>
is comprised of approximately 6,000 species in 225 genera and 26 tribes (<xref rid="B1" ref-type="bibr">Alonso-Zarazaga and Lyal 2009</xref>
). Termed ‘bark and ambrosia beetles’ this weevil subfamily is ubiquitous in forests worldwide. Many species contribute to the decomposition of dead vegetation while others are capable of causing substantial host mortality. True bark beetles, including <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
</named-content>
</italic>
, feed exclusively on phloem and cambium of living, declining, or dead trees and some species specialize on different plant parts from root to fruit and pith (<xref rid="B148" ref-type="bibr">Wood 1982</xref>
). Beetle feeding on phloem and xylem hastens the decomposition of trees and the introduction of other xylophagous organisms (<xref rid="B126" ref-type="bibr">Stokland 2012</xref>
). Some bark beetle species kill live trees by passively introducing fungi into otherwise healthy hosts as a by-product of phloem feeding and the galleries may girdle the host causing mortality (<xref rid="B148" ref-type="bibr">Wood 1982</xref>
). At high density these species cause widespread destruction of economically valuable tree species, giving bark beetles their nefarious reputation as ecologically and economically destructive forest pests (<xref rid="B55" ref-type="bibr">Furniss and Carolin 1977</xref>
). Other economically important bark beetle genera such as <italic><named-content content-type="taxon-name"><named-content content-type="genus">Dendroctonus</named-content>

species are monogamous. Females select brood material and begin galley construction. Males walk across the host material in search of females. Mating occurs with the female in the entrance tunnel and the male on the bark. However, mating in twig crotches has been reported for <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>

</italic>
(<xref rid="B129" ref-type="bibr">Svihra and Clark 1980</xref>
). The female creates an entrance tunnel at a 45° angle, boring through the bark to the cambium. From the entrance tunnel, she excavates a nuptial chamber and, depending on the species, one or two egg galleries in either direction from the entrance tunnel. The nuptial chamber and galleries are excavated in the cambium but also etch the sapwood. Females excavate egg niches on both sides of the egg galleries and a single egg is deposited in each niche and covered with boring dust. Adult males assist in removing frass and generally stay with the female until egg gallery construction is complete. The male then leaves the gallery and the female dies in the entrance tunnel with her abdomen projecting onto the bark surface. Larval galleries radiate away from the egg tunnels as they feed on phloem, also etching the sapwood. Once larvae mature, the prepupae burrow into the outer sapwood and pupate. The brood overwinters as pupae and adults emerge in the spring (<xref rid="B42" ref-type="bibr">Edson 1967</xref>

<p>A single apical, unarmed spine-like process that curves toward and extends beyond the process of the inner apical angle of the protibia and by a seven-segmented funicle readily distinguishes the tribe. All display a strongly sexually dimorphic head bearing hair-like setae, with the male frons variously excavated and female frons typically flat to convex. The eye is entire and the posterior area of head is subtruncate. The pronotum is unarmed with a costate lateral margin. In addition, the metapleural suture descends subventrally to the groove, receiving the groove on the costal margin of the elytra, then turns abruptly and parallels the groove near the metacoxal process (<xref rid="B144" ref-type="bibr">Wood 1972</xref>

species are generally recognized based on differences in male morphology, specifically shape of the venter concavity or lack thereof, ascending angle and protrusion of the basal margin of the second abdominal ventrite, the placement and shape of the spine or lack thereof on the second ventrite, the presence or absence of a spine on the margin of ventrite 2 and 3 and frons aciculation and vestiture. Differences among species are generally subtle and substantial knowledge of the intraspecific variation is needed for accurate identifications. In addition, there is a paucity of diagnostic morphological characters for females; to date diagnostic characters are known only for females of hardwood-feeding species (<xref rid="B120" ref-type="bibr">Smith and Cognato 2010a</xref>
). Association with a male or comparison to previously identified specimens is needed to determine the species of female specimens of conifer-feeders. Previous keys (<xref rid="B83" ref-type="bibr">LeConte 1876</xref>

<p>Unlike previous investigations (<xref rid="B10" ref-type="bibr">Blackman 1934</xref>

).</p>
<p>Specimens were examined using either a Leica (Wetzlar, Germany) MZ125 or MZ16 compound microscope and illuminated with a SCHOTT (Mainz, Germany) 150W halogen light source (model ACE®1). Images were taken with a Visionary Digital Passport II system (Palmyra, VA) using a Canon EOS 5D Mark II, 58.0 mm Canon Macro photo lens, Canon Speedlite transmitter ST-E2, two Canon Speedlite 4303X II flashes and a Stack Shot (Cognisys, Inc, Kingsley, MI). Montage images were assembled using Helicon Focus Mac Pro 4.2.8 (Helicon Soft, Kharkov, Ukraine). Measurements were made using an ocular micrometer on the same microscope and light source as listed above and calibrated with ROK (Shenzhen, China) 150.0 mm digital calipers (model DC-122A) following the protocol of <xref rid="B121" ref-type="bibr">Smith and Cognato (2010b)</xref>
. Measurements were taken from the specimen’s dorsal surface. Length was measured from the pronotum apex to the elytral apex. Width was measured at the widest part of the pronotum. Proportions are given as the ratio of length to width. A maximum of 50 specimens selected to encompass the known distribution were measured for each species. If important locality data such as state or county was missing from specimen labels, the information was inserted between square brackets in the material examined.

exhibits strong sexual dimorphism of the frons and abdominal venter; males display a wide array of morphological features, particularly on the venter, whereas females are more morphologically conserved. Consequently, characters were predominately male based. Male genitalia was found to be autapomorphic or extremely conserved in structure and thus characters were not scored. Characters and character state numbers correspond to data coded in the morphological data matrix for each taxon. The character matrix (Table <xref ref-type="table" rid="T3">3</xref>
) was constructed and edited using the online database MX (<xref rid="B153" ref-type="bibr">Yoder et al. 2006</xref>
). Character transformations were evaluated using MacClade 4.0 PPC (<xref rid="B91" ref-type="bibr">Maddison and Maddison 2000</xref>
) and homology of characters and definitions of characters states were re-examined and modified if necessary.</p>

<p>Forty-three characters were used in this study (19 binary and 24 multistate). Ten morphological characters were coded from the head, two from the thorax, ten from the elytra, one from the metepimeron, and 17 from the venter. Three ecological characters were also coded. Consistency and retention index values from the morphological phylogeny (Fig. <xref ref-type="fig" rid="F2">2</xref>

<p>DNA was extracted from freshly collected specimens preserved in 200 proof ethanol and from pinned specimens killed in sawdust impregnated with ethyl acetate and immediately pinned. Specimens were dissected by removing the head and thorax from the abdomen. DNA extractions were performed on the head and thorax using a Qiagen DNEasy blood and tissue kit (Hilden, Germany) following manufacturer protocols except for the DNA elution procedure, which consisted of a single elution of 100–200 µl of buffer AE depending on the size of the specimen, with specimens measuring less than 5.0 mm in length receiving 100 µl and those greater than 5.0 mm in length receiving 200 µl. After the extraction process was completed, the body parts were rinsed in 70% ethanol, glued onto a mounting board, pinned, labeled and were vouchered in the MSUC.

fied DNA was used to amplify partial gene regions of COI, D2 region of nuclear ribosomal 28S, CAD, and Argenine Kinase (ArgK) using the PCR primers listed in Table <xref ref-type="table" rid="T5">5</xref>
. The COI barcoding primers LCO 1490 and HCO 2198 did not consistently amplify scolytine COI sequences, which necessitated the construction of the degenerate scolytine specific primers, 1495b and rev750. These primers worked best for <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>

specimens and have proven to be effective on a broad array of scolytine taxa (Cognato et al. unpublished). The 1495b and rev750 primers were used to create the <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>

specific F215 and Rev453 primers, respectively for 5–20 years or older pinned specimens. All PCR cocktails consisted of a total volume of 25 µl and included 14.25–17.25 µl ddH<sub>2</sub>
O, 2.5 µl 10X PCR buffer (Qiagen), 1.0 µl 25 mM MgCl<sub>2</sub>
(Qiagen), 0.5µl dNTP mix (Qiagen), 2–5 µl DNA temfig, 0.25 µl HotStar Taq DNA polymerase (Qiagen). PCR reactions were performed on a thermal cycler (PTC-2000, MJ Research, Waltham, MA, USA or MyCylcer Thermocycler, BioRad, Hercules, CA, USA) under the following conditions: one cycle for 15 min at 95 °C, 40 cycles for 30 (COI)–45 (28S, CAD, ArgK) sec at 94 °C, 45 sec at 50–58 °C (see Table <xref ref-type="table" rid="T5">5</xref>
for specific annealing temperatures), 1 min at 72 °C and a final elongation cycle of 5 min at 72 °C. PCR products were cleaned using ExoSAP-IT (USB Corp., Cleveland, OH, USA) and following the manufacturer protocols. Cleaned PCR products were then prepared for sequencing. Each reaction contained 3.5 µl of cleaned PCR product, 1 µl 33 pM/µl sequencing primers (identical to those used in PCR), and 7.5 µl of ddH<sub>2</sub>
O. Samples were sequenced in the Michigan State University Research Technology Support Facility using a BigDye Terminator v 1.1 (Applied Biosystems, Foster City, CA, USA) and visualized using an ABI 3730 Genetic Analyzer (Applied Biosystems).</p>

<p>Sequences were received as chromatograms and the sense and antisense strands were compiled using Sequencher (Ann Arbor, MI) to trim sequences, examine for ambiguities and create consensus sequences. Sequences were blasted in GenBank to examine for paralogous copies and other potential problems including contamination and pseudogenes. Sequences for COI, CAD and ArgK were aligned using SE-AL v.2.0a11 Carbon (<ext-link ext-link-type="uri" xlink:href="http://tree.bio.ed.ac.uk/software/seal/">http://tree.bio.ed.ac.uk/software/seal/</ext-link>
). Sequence length variation was only observed in 28S. Sequences of 28S were manually aligned in SE-AL using a scolytine-specific secondary structure model (<xref rid="B73" ref-type="bibr">Jordal et al. 2008</xref>

<xref rid="B138" ref-type="bibr">Wheeler and Platnick 2000</xref>
). These monophyletic groups of individuals were named if they were diagnosable by synapomorphies or a unique combination of homoplastic characters. If diagnostic characters were not found, the clade retained the original species name or was synonymized with the sister clade. Therefore, given our species level morphological and molecular phylogenies, species revisions were based on monophyly of multiple individuals from disjunct populations.</p>

A phylogeny was reconstructed using the criterion of parsimony implemented in PAUP*4.0 b10 PPC (<xref rid="B133" ref-type="bibr">Swofford 2002</xref>
). A heuristic search with 1,000 stepwise random additions with tree bisection-reconnection (TBR) for 37 taxa (25 ingroup, 12 outgroup) was performed. Characters were unordered and equally weighted. Bootstrap values were calculated by performing 1,000 pseudoreplicates with simple additions in PAUP*. Bremer support values were calculated by creating a constraint tree in TreeRot v.2 (<xref rid="B123" ref-type="bibr">Sorenson 1999</xref>

We analyzed the molecular and morphological datasets using Bayesian estimation of phylogeny with MrBayes 3.2.2 (<xref rid="B110" ref-type="bibr">Ronquist et al. 2012</xref>
) on the CIPRES Science Gateway (<xref rid="B116" ref-type="bibr">Schwartz 2010</xref>
). The Bayesian analysis consisted of a combined molecular and morphological dataset (82 taxa). The dataset was divided into 11 partitions by gene and codon position for COI, CAD and ArgK, and one partition each for 28s and morphology. We selected the best model for each data partition using MrModeltest (<xref rid="B100" ref-type="bibr">Nylander 2004</xref>
). The GTR+I+Γ (general time reversible with a proportion of invariant sites and a gamma-shaped distribution of rate variation across sites) model selected by AIC was found to have the optimal fit for the gene partitions and Γ (gamma) was chosen for the morphology partition. Taxa that were unable to be sequenced were included in the morphology partition of the combined dataset.</p>
<p>Four Metropolis-Coupled Markov Chain Monte Carlo searches (3 heated, 1 cold) were performed for 10 million generations with sampling as described for the molecular dataset. <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>

<sec sec-type="Terminology"><title>Terminology</title>
<p>There are some traditionally used terms and characters in <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
</named-content>
</italic>
literature that require clarification. The term ‘venter’ is regularly utilized. In general, the term refers to the entire ventral surface of an organism. However in <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
</named-content>
</italic>
it only pertains to the abdominal ventral concavity, specifically ventrites 2–5. The length of ventrite 5 compared to ventrite 3 and 4 is another common misleading character in <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
</named-content>
</italic>
literature. Rather than measuring the entire length of segment 5, only the distance from the basal margin to the subapical carinate ridge is measured and compared to the combined lengths of ventrites 3 and 4. The following <italic>Glossary</italic>

<p>Based on the results of our phylogenetic analyses, 25 species occur in the Nearctic. Several species were not recovered as monophyletic and had less than 1% difference in all genes sequences (Table <xref ref-type="table" rid="T6">6</xref>
). These species are thus placed in synonymy with the oldest described species. The following synonyms were discovered: <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>

Length 1.7–6.0 mm, 1.7–2.9 times as long as wide. Color variable, red-brown to black. Teneral adults are often light brown.</p>
<p>Head visible from above. Frons flattened to convex, sexually dimorphic (discussed below for each species group or clade). Eye elongate, sinuate to shallowly emarginated, finely faceted. Antennal scape club shaped, shorter than four funicle segments; funicle seven-segmented; club larger than funicle, flattened, oval to obovate, minutely pubescent and with 3 strongly procurved sutures, suture 1 partially to completely septate and with or without a surface groove. Pronotum large, wider than long; lateral and basal margins marked by a fine elevated line; disc finely punctate. Scutellum triangular, deeply depressed below elytral surface. Elytra depressed around scutellum and along basal one-fifth to half-length of elytral suture. Elytra wider than pronotum, flattened; striae punctate; interstriate punctate, with or without setae. Venter either gradually ascending from apical margin of ventrite 1 to elytral apex, or ventrite 2 abruptly ascending, sexually dimorphic, with or without tubercules and/or carinae; remaing ventrite usually unarmed, may have various armature or elevated margins, especially in males. Procoxae narrowly separated. Protibia rectangular; sides straight, nearly parallel, without denticles; outer distal angle produced into a curved uncus.</p>

<p>This species colonizes dying and weakened limbs of its host as well as fresh slash. Typical host material is 15.0–38.0 cm in diameter but branches as small as 8.0 cm are colonized (<xref rid="B103" ref-type="bibr">Pechuman 1938</xref>
).</p>
<p>Adult galleries are somewhat variable and are either parallel or at a slight oblique angle to the grain of the wood and consisting of a nuptial chamber and a single egg gallery. The adult gallery strongly scores the sapwood and ranges in size from 3.5–6.0 cm in length. Egg niches are constructed along the gallery and score the sapwood. Six to 100 eggs may be laid along the egg galleries with the typical gallery having 40 eggs. Larval mines lightly score the sapwood and radiate perpendicular to the egg gallery. Larval galleries later meander often at an oblique angle to the grain of wood, forming a fan shaped pattern. Pupation occurs within the sapwood and broods overwinter as larvae or adults. The following year, adults emerge and feed at twig crotches before selecting host material (<xref rid="B103" ref-type="bibr">Pechuman 1938</xref>

females produce an aggregation pheromone to aggregate conspecifics to host trees. The pheromone bouquet is composed of three components: (-)-4-methyl-3-heptanol, (-)-2,4-dimethyl-5-ethyl-6,8-dioxabicylo[3.2.1]octane (α)-multistriatin and (-)-α-cubebene (<xref rid="B102" ref-type="bibr">Pearce et al. 1975</xref>
).</p>
<p>Mating can occur either as the female is undergoing maturation feeding in twig crotches or within the gallery as described for the genus (<xref rid="B129" ref-type="bibr">Svihra and Clark 1980</xref>
). The adult gallery is excavated parallel to the grain of the wood and consists of a single egg gallery; a nuptial chamber is not constructed. The adult gallery ranges in size from 2.5–5.0 cm in length. Egg niches are constructed along the gallery and score the sap<pmc-comment>PageBreak</pmc-comment>
<pmc-comment>PageBreak</pmc-comment>
wood. Twenty-four to 96 eggs may be laid singly along the egg gallery. Larval mines lightly score the sapwood and radiate perpendicular to the egg gallery. Larval galleries later meander often at an oblique angle to the grain of wood, forming a fan shaped pattern. Larvae construct pupal chambers in the bark (<xref rid="B17" ref-type="bibr">Bright 1976</xref>
).</p>
<p>There are one to one-half generations per year in Canada and three in the southern US (<xref rid="B52" ref-type="bibr">Furniss and Johnson 2002</xref>
). In Canada, adults emerge in June and July and feed at twig crotches of healthy trees for 7–10 days before selecting host material (<xref rid="B25" ref-type="bibr">Chamberlin 1958</xref>
; <xref rid="B5" ref-type="bibr">Baker 1972</xref>
; <xref rid="B129" ref-type="bibr">Svihra and Clark 1980</xref>

). Adults become covered in fungal spores upon emergence from brood material. Adults inoculate elms with the Dutch elm disease fungus as they feed in twig crotches (<xref rid="B129" ref-type="bibr">Svihra and Clark 1980</xref>

primarily attacks and kills small twigs and branches but may kill whole trees through the process of excavating adult galleries and larval feeding. Twig injury is the result of feeding activity at the base of the bud. Attacks can begin near an injury or on a healthy tree (<xref rid="B24" ref-type="bibr">Chamberlin 1939</xref>
; <xref rid="B20" ref-type="bibr">Bright and Stark 1973</xref>
).</p>
<p>The adult gallery is parallel to the grain of the wood and solely consists of an egg gallery; a nuptial chamber is not constructed. The adult gallery strongly scores the cambium, lightly scores the sapwood and ranges in size from 1.0–5.0 cm in length (Bright and Stark 1976; <xref rid="B52" ref-type="bibr">Furniss and Johnson 2002</xref>
). Eggs are laid singly in larval niches on both sides of the egg gallery. Larval mines first radiate perpendicular to the egg gallery against the grain of the wood and later turn parallel to the grain (<xref rid="B20" ref-type="bibr">Bright and Stark 1973</xref>
). The larval stage typically lasts one month. Pupation occurs in the bark for summer emergence. If the brood is unable to complete development during the warmer months, larvae will burrow 1.0–2.0 cm deep within the sapwood to overwinter. The following year, adults emerge and feed at twig crotches before selecting host material (<xref rid="B5" ref-type="bibr">Baker 1972</xref>
). There are one to four generations per year depending on locality, with more generations occurring in warmer climates (<xref rid="B31" ref-type="bibr">Chittenden 1898</xref>

<p>This species is very rarely encountered. Most museum collections occurred in the early 1900’s and most recent collections have been from Lindgren funnel traps.

<p>The biology of this species is poorly understood. Adult galleries are parallel to the grain of the wood and consist of a single egg gallery; a nuptial chamber is not constructed. The adult gallery strongly scores the sapwood and ranges in size from 2.5–5.0 cm in length (<xref rid="B9" ref-type="bibr">Blackman 1922</xref>
). Larval mines first radiate perpendicular to the egg <pmc-comment>PageBreak</pmc-comment>

). Larvae construct pupal chambers in burrows 2.0–3.0 cm deep within the sapwood (<xref rid="B17" ref-type="bibr">Bright 1976</xref>

kills its host by mass attack in which a multitude of broods develop in the phloem and cambium, effectively girdling the host tree (<xref rid="B9" ref-type="bibr">Blackman 1922</xref>
).</p>
<p>Adult galleries are parallel to the grain of the wood and deeply score the sapwood; a nuptial chamber is not constructed. The adult gallery is short (2.5–5.0 cm), and consists of a single egg gallery (<xref rid="B9" ref-type="bibr">Blackman 1922</xref>
). Eggs are deposited singly in niches on each side of the egg gallery with 20–60 niches per gallery (<xref rid="B9" ref-type="bibr">Blackman 1922</xref>
). After the eggs have been laid, the female constructs a postovipositional feeding tunnel parallel to the egg gallery (<xref rid="B61" ref-type="bibr">Goeden and Norris 1965b</xref>
). Larval mines are excavated in the cambium. From the egg gallery, the larval mines are first perpendicular to the grain of the wood and then gradually turn and diverge creating a fan shaped appearance. The larvae bore into the inner bark to overwinter. Larvae pupate the following spring and emerge as adults the following summer (<xref rid="B9" ref-type="bibr">Blackman 1922</xref>
). Upon emergence, adults feed at twig crotches <pmc-comment>PageBreak</pmc-comment>

, is restricted to the Santa Lucia Mountains of California. The tree is distributed in small patches in deep, moist canyon bottoms as well as dry, rocky slopes and ledges within Los Padres National Forest in Monterey County, especially near Cone Peak and Church Creek (<xref rid="B62" ref-type="bibr">Griffin and Critchfield 1972</xref>

) but is also reported from larger limbs and fresh slash (<xref rid="B42" ref-type="bibr">Edson 1967</xref>
).</p>
<p>The adult gallery somewhat resembles an expanded ‘E’ (Fig. <xref ref-type="fig" rid="F24">24</xref>
). The gallery is parallel to the grain of the wood and consists of a central nuptial chamber and two egg galleries, one below and one above the nuptial chamber. Each egg gallery ends in a pronounced hook. Galleries strongly score the cambium and lightly score the sapwood. The adult gallery averages 2.5–12.0 cm in length (<xref rid="B14" ref-type="bibr">Bright 1964</xref>
; <xref rid="B42" ref-type="bibr">Edson 1967</xref>
). Egg niches are closely spaced on both sides of the maternal gallery (<xref rid="B20" ref-type="bibr">Bright and Stark 1973</xref>
). Larval mines are first perpendicular to the egg gallery and later turn to form a fan shaped pattern before terminating at pupation chambers in the sapwood (<xref rid="B42" ref-type="bibr">Edson 1967</xref>
).</p>

<p>2.3–4.0 mm long (mean = 3.1 mm; n = 15); 1.8–2.5 times as long as wide. Head, pronotum, and abdominal venter dark red-brown to black, elytra and legs light brown, antennae yellow-brown. Pronotum typically darker than elytra.</p>
<p><italic>Head.</italic>
Epistoma weakly emarginated; epistomal process present, moderately developed and elevated; median area above mandibles bearing dense patch of long yellow hair-like setae. Frons appearing flattened when viewed laterally from epistoma to vertex, moderately transversely impressed just above epistoma to vertex; strongly, coarsely, longitudinally aciculate-punctate; aciculations converging at epistoma; punctures sparse, large, coarse; moderately to densely uniformly covered by long, fine, yellow, erect, hair-like setae, these longer than width of midpoint of eye. Antennal scape short, elongate; club flattened, irregularly ovoid, setose with partial septum, two arcuate sutures visible.</p>
<p><italic>Pronotum</italic>
wider than long; apical margin broadly rounded, median area between eyes lined with scales; sides distinctly arcuate, strongly constricted near apex, forming a weak transverse impression near apical margin; surface smooth, shining, punctures on disc fine, shallow, moderately abundant, larger and more abundant laterally and on apical constriction; apical and anterolateral margins bearing sparse, erect, yellow, hair-like setae; base weakly bisinuate.</p>
<p><italic>Elytra</italic>
with sides sub-parallel on apical half, narrowing to subquadrate, smooth apex; apex moderately emarginated at suture. Margin of apical edge bearing large, coarse punctures. Disc smooth, shining; interstriae not impressed, twice width of striae, punctures uniseriate, smaller than those of striae, bearing minute, recumbent setae length of interstrial punctures (may be abraded); striae weakly impressed. Declivity bearing sparse, short, erect, yellow setae. Metepimeron less than half-length of metanepisternum.</p>
<p><italic>Venter.</italic>
Apical margin of ventrite 1 rounded, marked by weak carina on ascendant part of venter. Ventrite 2 nearly perpendicular to ventrite 1; surface smooth, shining, finely punctate; punctures small, fine, shallow; covered with sparse setae less than length of segment 3; surface convex; apical margin armed with laterally compressed, median spine with base extending from apical margin to ¾ length of segment, apex rounded, rarely a slightly elevated vertical carina (Oregon: Dixie Pass and Frog Lake) instead of spine; lateral margins of ventrites 2–3 and ventrite 4 unarmed. Ventrite 5 carinate ridge equidistant between basal and apical margins of segment; length of ventrite 5 less than combined lengths of ventrites 3 and 4; setal patch and median depression absent.</p>

<p>The adult gallery is parallel to the grain of the wood and consists of two egg galleries and a central nuptial chamber (Fig. <xref ref-type="fig" rid="F24">24</xref>
). The central nuptial chamber extends at a right angle to the rest of the gallery and opposite the nuptial chamber is a rounded turning niche.

</italic>
. Egg galleries are extended parallel to the grain of the wood. The adult gallery scores the sapwood more deeply than the cambium, and ranges in length from 6.4–11.5 cm. The female constructs widely spaced egg niches on both sides of each egg gallery. Larval mines extend against the grain of wood and gradually diverge before terminating at pupation chambers that deeply score the sapwood (<xref rid="B42" ref-type="bibr">Edson 1967</xref>

Egg niches are generally placed in pairs along the egg galleries and score the sapwood. Larvae extend their mines perpendicular to the egg gallery before diverging in a fan shaped pattern.

, figs 130–131). Eggs are laid in niches excavated on each side of the central nuptial chamber. The larval mines extend parallel to the grain of wood and are first in the cambium and later penetrate into the sapwood. Pupation occurs in the sapwood and there are two generations per year with the first generation occurring from October to May and the second from June to October (<xref rid="B32" ref-type="bibr">Cibrián Tovar et al. 1995</xref>

is an uncommonly encountered species. The species prefers to colonize the limbs, tops and slash of its host. Infested material ranges from 3.0–10.0 cm in diameter (<xref rid="B148" ref-type="bibr">Wood 1982</xref>
).</p>
<p>The adult gallery contains two egg galleries that branch from the central nuptial chamber. One egg gallery extends from the nuptial chamber perpendicular to the grain of wood and the second gallery extends at a 45° angle to the grain (Fig. <xref ref-type="fig" rid="F24">24</xref>
). Galleries are frequently initiated near branch crotches and disguised under rough patches of bark. The adult gallery deeply scores the sapwood and lightly scores the cambium. The adult galleries range in size from 1.9–6.5 cm in length. Eggs are laid in niches on both sides of each egg gallery and larval mines radiate perpendicular to the egg gallery forming a fan shaped pattern. The larval mines gradually diverge and lightly etch the sapwood. Pupation occurs in the sapwood (<xref rid="B42" ref-type="bibr">Edson 1967</xref>
).</p>

<p>The adult gallery is typically constructed parallel to the grain of the wood and has a central nuptial chamber (Fig. <xref ref-type="fig" rid="F24">24</xref>
). The gallery structure is typically bayonet shaped but may also be longitudinal. Each egg gallery extends in opposite directions to the grain of the wood from the central nuptial chamber. The nuptial chamber is transverse to the egg galleries. The adult gallery deeply scores the sapwood and lightly scores the <pmc-comment>PageBreak</pmc-comment>

cambium. The adult gallery averages 6.0–18.0 cm in length. Egg niches are closely spaced and deeply score the sapwood.

<sec sec-type="treatment-Description (male)"><title>Description (male).</title>
<p>2.5–3.0 mm long (mean = 2.4 mm; n = 12); 2.3–2.7 times as long as wide. Color red-brown to dark red brown, antennae yellow-brown, legs dark red-brown to yellow brown apically. Pronotum typically darker than elytra.</p>
<p><italic>Head.</italic>
Epistoma weakly emarginate; epistomal process present, moderately developed, low; median area above mandibles bearing dense patch of long, yellow, hair-like setae. Frons appearing flattened when viewed laterally from epistoma to vertex, slightly transversely impressed just above epistoma to inner apices of eyes; moderately, coarsely longitudinally aciculate-punctate; aciculations converging at epistoma; punctures large, dense, coarse; moderately, uniformly covered by long, fine, yellow, erect, hair-like setae, these longer than width of midpoint of eye. Antennal scape short, elongate; club flattened, irregularly ovoid, setose with partial septum, two arcuate sutures visible.</p>
<p><italic>Pronotum</italic>
wider than long; apical margin broadly rounded, median area between eyes lined with scales; sides distinctly arcuate, strongly constricted near apex, forming a weak transverse impression near apical margin; surface smooth, shining, punctures on disc fine, shallow, moderately abundant, larger and more abundant laterally and on apical constriction; apical and anterolateral margins bearing sparse, erect, yellow, hair-like setae; base weakly bisinuate.</p>
<p><italic>Elytra</italic>
with sides sub-parallel on apical half, narrowing to subquadrate, smooth apex; apex weakly emarginated at suture. Margin of apical edge bearing large, coarse punctures. Disc glabrous, smooth, shining; interstriae weakly impressed, more than twice width of striae, punctures uniseriate, smaller than those of striae; striae weakly impressed. Declivity bearing sparse, short, erect, yellow setae. Metepimeron half-length of metanepisternum.</p>
<p><italic>Venter.</italic>
Apical margin of ventrite 1 rounded, marked by weak carina on ascendant part of venter, more strongly marked laterally. Ventrite 2 nearly perpendicular to ventrite 1; surface reticulate, shagreened, dull, finely punctate; punctures small, fine, shallow punctures; covered with sparse setae that are about twice size of a puncture; surface convex; armed with large conical median spine, apex rounded; lateral margins of ventrites 2–3 and ventrite 4 unarmed. Ventrite 5 carinate ridge closer to apical margin of segment; length of ventrite 5 less than combined lengths of ventrites 3 and 4; setal patch and median depression absent.</p>

) and is commonly found in branches of fallen spruce and suppressed limbs of standing hosts (Smith, pers. obs.).</p>
<p>The adult gallery is parallel to the grain of the wood and bayonet shaped (Fig. <xref ref-type="fig" rid="F24">24</xref>
). From the central nuptial chamber, one egg gallery extends to the grain of the wood and the other egg gallery is slightly transversely extended and then extends parallel to the grain. The nuptial chamber is oblique to the egg galleries. The adult gallery equally scores the sapwood and cambium but in some instances may only lightly score the sapwood. Adult galleries average 5.0–8.0 cm in length. Ten to 30 egg niches are widely spaced and deeply score the sapwood. Larvae extend their mines perpendicular to the egg gallery before diverging in a fan shaped pattern. Pupation may occur under the bark or in the sapwood (<xref rid="B42" ref-type="bibr">Edson 1967</xref>
; <xref rid="B20" ref-type="bibr">Bright and Stark 1973</xref>

<p>The adult gallery contains two egg galleries that branch from the central nuptial chamber. Typically, one egg gallery extends from the nuptial chamber perpendicular to the grain of wood and the second egg gallery extends at a 45° angle to the grain (Fig. <xref ref-type="fig" rid="F24">24</xref>
). Occasionally both egg galleries are extended obliquely to the grain, at a 45° angle to the grain or perpendicular to the grain (<xref rid="B42" ref-type="bibr">Edson 1967</xref>
). Galleries are frequently initiated near branch crotches and disguised under rough patches of bark. The adult gallery equally scores the sapwood and cambium. The adult galleries range in size from 2.5–6.4 cm in length. Eggs are laid in niches on both sides of each egg gallery and larval mines radiate perpendicular to the egg gallery. The larval mines gradually diverge forming a fan shaped pattern and lightly etch the sapwood. Pupation occurs in the sapwood (<xref rid="B42" ref-type="bibr">Edson 1967</xref>
). There is one generation per year and broods overwinter as larvae (<xref rid="B52" ref-type="bibr">Furniss and Johnson 2002</xref>

<p>Males exhibiting the reflexus phenotype are readily distinguished by the presence of a strong recurved subapical carinate ridge on ventrite 5 that is medially produced to form a slightly recurved and subrostriform ridge that appears “reflexed”. Males of this species exhibiting the wickhami phenotype are easily confused with males of <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>

<p>2.4–3.8 mm long (mean = 3.2 mm; n = 20); 1.8–2.5 times as long as wide. Color dark red-brown to black, antenna brown. Pronotum typically darker than elytra.</p>
<p><italic>Head.</italic>
Epistoma weakly to acutely, deeply emarginate; epistomal process weakly to strongly developed and elevated; median area above mandibles bearing dense patch of long, yellow, hair-like setae. Frons appearing flattened when viewed laterally, slightly transversely impressed just above epistoma; moderately, longitudinally aciculate, deeply, coarsely punctate; aciculations converging at epistoma; punctures small, coarse; moderately, uniformly covered by long, fine, yellow, erect, hair-like setae, these longer than width of midpoint of eye. Antennal scape short, elongate; club flattened, irregularly ovoid, setose with partial septum, three sharply arcuate sutures visible.</p>
<p><italic>Pronotum</italic>
wider than long; apical margin broadly rounded, median area between eyes lined with scales; sides distinctly arcuate, strongly constricted near apex, forming a weak transverse impression near apical margin; surface smooth, shining, punctures on disc fine, shallow, moderately abundant, larger and more abundant laterally and on apical constriction; apical, anterolateral and lateral margins bearing sparse, erect, yellow, hair-like setae; base weakly bisinuate.</p>
<p><italic>Elytra</italic>
with sides sub-parallel on apical half, narrowing to subquadrate, smooth apex; apex moderately emarginated at suture. Margin of apical edge bearing small, fine punctures. Disc smooth, shining; interstriae weakly impressed, more than twice width of striae, punctures uniseriate, smaller than those of striae, bearing minute, recumbent setae less than length of a puncture; striae weakly impressed. Declivity bearing sparse, short, erect yellow setae. Metepimeron half-length of metanepisternum.</p>
<p><italic>Venter.</italic>
Apical margin of ventrite 1 rounded, marked by weak carina on vertical surface of segment. Ventrite 2 nearly perpendicular to ventrite 1; surface rugose, shagreened, finely punctate; punctures small, coarse, shallow; surface convex; setae moderately abundant, long, erect and longer than length of ventrite 3; lateral margins of ventrites 2–3 and ventrite 4 unarmed. Ventrite 5 typically armed with strong, recurved, subapical, carinate ridge, occasionally modified and medially produced to form a slightly recurved and subrostriform ridge appearing “reflexed” (Chiricahua Mountains, Arizona and Chihuahua, Mexico populations). Ventrite 5 carinate ridge closer to apical margin of segment; length of ventrite 5 less than combined lengths of ventrites 3 and 4; setal patch and median depression absent.</p>

is relatively common throughout its range and is found in fresh slash and branches of Douglas fir (<xref rid="B42" ref-type="bibr">Edson 1967</xref>
).</p>
<p>The adult gallery consists of two egg galleries and a central nuptial chamber. The adult gallery is parallel to the grain of the wood and bayonet shaped (Fig. <xref ref-type="fig" rid="F24">24</xref>
). From the central nuptial chamber, one egg gallery extends parallel to the grain of the wood and the other egg gallery is slightly transversely extended and then extends parallel to the grain. The nuptial chamber is oblique to the egg galleries. The adult gallery equally scores the sapwood and cambium and averages 3.9–7.6 cm in length. Egg niches are closely spaced and score the sapwood. Larvae extend their mines perpendicular to the egg gallery before diverging in a fan shaped pattern. Pupation may occur under the bark or in the sapwood (<xref rid="B42" ref-type="bibr">Edson 1967</xref>

, but as discussed above, never formally placed it in synonymy. All three species are here treated as one slightly morphologically variable species. We assessed intraspecific variation within these three species for four genes (Table <xref ref-type="table" rid="T6">6</xref>
). It was small for each gene with the average divergence of 1.3% for COI and less than 0.12%, 0.03% and 0.29% for 28S, CAD and ArgK respectively among sampled populations (Table <xref ref-type="table" rid="T6">6</xref>
). These ranges are consistent with variation observed within other species. There are two main characteristics found that vary among the populations: the male fifth ventrite carina and the male epistomal process. There are two main phenotypes observed in populations: reflexus and wickhami. The reflexus phenotype includes individuals that were previously considered to be <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
<named-content content-type="species">reflexus</named-content>
</named-content>
</italic>
with the male ventrite 5 armed with a strong recurved subapical carinate ridge that at its crest is closer to the basal than the apical margin of the segment. The length and height of the subapical carinate ridge is also variable within populations. This character is only found in the Chiricahua Mountains, Arizona and in Mexico. The wickhami phenotype includes individuals that were formerly considered <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
<named-content content-type="species">wickhami</named-content>
</named-content>

</named-content>
</italic>
. In the wickhami phenotype the process on the male fifth ventrite is reduced in the wickhami phenotype and but still forms strong recurved subapical carinate ridge. However it is important to note that both the reflexus and wickhami phenotypes are sympatric in the Chiricahua Mountains. The male epistomal process also varies from a strongly developed and elevated ridge above the epistoma to weakly developed and elevated ridge. In general, the ridge is more strongly developed in the reflexus phenotype but considerable variation is observed especially in the wickhami phenotype. Additional variation is observed in the density of punctures on the male second ventrite and the coarseness of the male frons aciculations. In addition, the gallery structure of <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>

is found in the limbs and tops of its host and fresh slash. Galleries are often initiated near limb bases (<xref rid="B42" ref-type="bibr">Edson 1967</xref>
).</p>
<p>The adult gallery contains two egg galleries that branch from the central nuptial chamber. Gallery shape is quite variable and ranges from ‘S’ shaped at an oblique angle to the grain to nearly perpendicular against the grain (Fig. <xref ref-type="fig" rid="F25">25</xref>
). Typically one egg gallery obliquely extends from the central nuptial chamber against the grain of wood for a short distance before becoming apically recurved. The second egg gallery is identical to the first but runs in the opposite direction. However galleries may extend perpendicular <pmc-comment>PageBreak</pmc-comment>
<pmc-comment>PageBreak</pmc-comment>
to the grain of the wood or may not be apically recurved. The adult gallery deeply scores the sapwood and ranges in size from 2.5–7.0 cm in length. Egg niches are distinct, score the sapwood and are closely spaced along the egg galleries. Larval mines rapidly diverge perpendicular to the adult gallery and are parallel to the grain of the wood. Larval mines terminate in pupation chambers that score the sapwood (<xref rid="B42" ref-type="bibr">Edson 1967</xref>

species. They are epsilon (“<bold>ε</bold>
”) shaped and deeply excavated in the sapwood (Fig. <xref ref-type="fig" rid="F25">25</xref>
). The gallery consists of a central nuptial chamber and two egg galleries that are recurved around the nuptial chamber (<xref rid="B42" ref-type="bibr">Edson 1967</xref>
). The adult gallery is 2.0–5.0 cm in length and varies by branch size, with larger branches having larger galleries (<xref rid="B53" ref-type="bibr">Furniss and Kegley 2011</xref>
). Egg niches lightly score the sapwood. In Oregon 12–30 eggs are laid per gallery and in Idaho the upper limit appears to be 12 (<xref rid="B53" ref-type="bibr">Furniss and Kegley 2011</xref>
). Larval mines radiate from the egg gallery in all directions, often crossing each other. The larval mines are located in the phloem and cambium for about the first centimeter of their length. After the first centimeter, larval mines lightly score the sapwood. Pupation chambers are formed in the cambium or outer bark. There is one generation per year and the brood overwinters as larvae. In Idaho, flight occurs in July and adults leave the gallery once eggs have been laid (<xref rid="B53" ref-type="bibr">Furniss and Kegley 2011</xref>

is an uncommon and poorly studied species. The adult galleries are typically perpendicular to the grain of the wood and 4.0–10.0 cm in length (Fig. <xref ref-type="fig" rid="F25">25</xref>
) (<xref rid="B42" ref-type="bibr">Edson 1967</xref>
; <xref rid="B52" ref-type="bibr">Furniss and Johnson 2002</xref>
). Adult galleries score the cambium slightly more than the sapwood. However, <xref rid="B42" ref-type="bibr">Edson (1967)</xref>
reported that specimens from a series in northern California produced an adult gallery that was oriented obliquely to the grain of the wood. Galleries consist of a central nuptial chamber and two egg galleries. Each egg gallery is extended perpendicular to the grain of the wood from the central nuptial chamber. Egg niches are irregularly spaced and faintly score the sapwood. Larval tunnels are extended parallel to the grain of the wood, etching the sapwood lightly at first and deeply near the pupation chamber. There is one generation per year and broods overwinter as larvae (<xref rid="B52" ref-type="bibr">Furniss and Johnson 2002</xref>

<p>The adult gallery of this species consists of a single egg gallery that extends with the grain of the wood (Fig. <xref ref-type="fig" rid="F25">25</xref>
). The nuptial chamber includes a short extension at a 45° angle from the egg gallery and is located at one end on the egg gallery. The gallery deeply scores the sapwood and lightly scores the cambium (<xref rid="B25" ref-type="bibr">Chamberlin 1958</xref>

Epistoma weakly emarginate; epistomal process weakly elevated; median area above mandibles bearing dense patch of long, yellow, hair-like setae. Frons appearing convex when viewed laterally, slightly transversely impressed just above epistoma; moderately, coarsely, longitudinally aciculate-punctate; aciculations converging at epistoma; punctures small, coarse; moderately, uniformly covered by long, fine, yellow, erect, hair-like setae, these longer than width of midpoint of eye. Antennal scape short, elongate; club flattened, irregularly ovoid, setose with partial septum, three arcuate sutures visible.</p>
<p><italic>Pronotum</italic>
wider than long; apical margin broadly rounded, median area between eyes lined with scales; sides distinctly arcuate, strongly constricted near apex, forming a weak transverse impression near apical margin; surface smooth, shining, punctures on disc fine, shallow, moderately abundant, larger and more abundant laterally and on apical constriction; apical and anterolateral margins bearing sparse, erect, yellow, hair-like setae; base weakly bisinuate.</p>
<p><italic>Elytra</italic>
with sides sub-parallel on apical half, narrowing to subquadrate, smooth apex; apex moderately emarginated at suture. Margin of apical edge bearing large, coarse punctures. Disc glabrous, smooth, shining; interstriae not impressed, more than twice width of striae, interstrial punctures uniseriate, smaller than those of striae; striae weakly impressed. Declivity bearing sparse, short, erect yellow setae. Metepimeron half-length of metanepisternum.</p>
<p><italic>Venter.</italic>
Apical margin of ventrite 1 weakly elevated above base of ventrite 2. Ventrite 2 nearly perpendicular to ventrite 1; surface glabrous, shagreened, dull, finely punctate; punctures small, fine, shallow; surface flattened; apical margin armed with broad median denticle, occasionally absent; lateral margins of ventrites 2–3 and ventrite 4 unarmed. Ventrite 5 carinate ridge closer to apical margin of segment; length of ventrite 5 less than combined lengths of ventrites 3 and 4; setal patch and median depression absent.</p>

to kill fir trees, this species is the most well studied native <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
</named-content>
</italic>
in North America. Attacks usually occur on the boles of weakened and stressed standing trees from a few feet above the base to the top of the tree, but can also occur in large slash and fresh and fallen trees (<xref rid="B25" ref-type="bibr">Chamberlin 1958</xref>
; <xref rid="B42" ref-type="bibr">Edson 1967</xref>
; <xref rid="B52" ref-type="bibr">Furniss and Johnson 2002</xref>
). Attacks at the top of the tree are more common on overmature standing trees during drought and healthy, vigorous trees are not preferred (<xref rid="B25" ref-type="bibr">Chamberlin 1958</xref>
; <xref rid="B106" ref-type="bibr">Raffa and Berryman 1987</xref>
). Trees can also become successively attacked over a period of years and slowly die. Healthy trees may survive the attacks but can develop rots and defects that reduce timber value (<xref rid="B127" ref-type="bibr">Struble 1937</xref>
). Unlike most tree-killing or primary bark beetles, <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>

does not have pheromone to aggregate conspecifics to host trees. The beetles locate suitable hosts via primary attraction to host volatiles (<xref rid="B89" ref-type="bibr">Macías-Sámano et al. 1998a</xref>
,<xref rid="B90" ref-type="bibr">b</xref>
).</p>
<p>Adult galleries are perpendicular to the grain of the wood (Fig. <xref ref-type="fig" rid="F25">25</xref>
), deeply score the sapwood, lightly score the cambium and consist of two egg galleries with a central nuptial chamber (<xref rid="B42" ref-type="bibr">Edson 1967</xref>
). The nuptial chamber is typically short and at a right angle to the egg galleries but may also extend at an oblique angle. When this occurs, one of the egg galleries is briefly extended at an oblique angle against the grain before becoming perpendicular to the grain (<xref rid="B42" ref-type="bibr">Edson 1967</xref>
). Eggs are deposited singly in triangular niches spaced 1.0–1.5 mm apart on each side of the egg gallery with 80–300 niches per gallery. Galleries range in size from 8.0–30.0 cm in length (<xref rid="B25" ref-type="bibr">Chamberlin 1958</xref>
; <xref rid="B42" ref-type="bibr">Edson 1967</xref>
; <xref rid="B20" ref-type="bibr">Bright and Stark 1973</xref>
; <xref rid="B52" ref-type="bibr">Furniss and Johnson 2002</xref>
). Larval mines are perpendicular to the egg gallery and parallel to the grain of the wood. Larval mines are also parallel to each other both above and below the egg gallery, giving the gallery a diamond shaped appearance (<xref rid="B77" ref-type="bibr">Keen 1938</xref>
; <xref rid="B42" ref-type="bibr">Edson 1967</xref>
). Larval mines lightly score the <pmc-comment>PageBreak</pmc-comment>
sapwood and deeply score the cambium. Larvae construct pupation chambers in the phloem or outer bark (<xref rid="B42" ref-type="bibr">Edson 1967</xref>
). Broods overwinter as larvae or adults (<xref rid="B20" ref-type="bibr">Bright and Stark 1973</xref>
). The number of generations per year varies both geographically and with elevation. Development time can range from as little as 41 days at low latitudes and elevations to as many as 380 days at high latitudes and elevations (<xref rid="B20" ref-type="bibr">Bright and Stark 1973</xref>
). There is typically one generation per year (<xref rid="B20" ref-type="bibr">Bright and Stark 1973</xref>
). In Idaho pupation occurs from June to July and peak flight occurs in July (<xref rid="B52" ref-type="bibr">Furniss and Johnson 2002</xref>

; <xref rid="B148" ref-type="bibr">Wood 1982</xref>
) apriori knowledge of the gender is not required. Only one sex is necessary to identify the specimen and host species or gallery types are not needed. Because the sexual dimorphic characters are not consistent for the Nearctic species (see sexual dimorphism discussion above), the sexes could not be evenly split. In general, males and females of native hardwood-feeding species will key out beginning at couplet 3 and both sexes of some <italic><named-content content-type="taxon-name"><named-content content-type="genus">Abies</named-content>

<p>Morphology failed to resolve the <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
</named-content>
</italic>
phylogeny and very few synapomorphic characters were found (Fig. <xref ref-type="fig" rid="F2">2</xref>
). Unique combinations of homoplastic characters define species limits. Characters that are among the most informative are sexually dimorphic and male including: male fifth ventrite carina (character 36), size and coarseness of frons punctures (character 7), first ventrite apical margin (character 27), second ventrite surface (character 29) and presence of an epistomal process (character 2). Other non-dimorphic informative characters included elytral apex emargination (character 20), host (character 43), and strial impression (character 18). The lack of phylogenetically informative characters necessitated the need for further investigation using molecular characters to illuminate species boundaries.</p>
<p>As in other phylogenetic studies, COI data failed to recover many species as monophyletic (Fig. <xref ref-type="fig" rid="F3">3</xref>
) (<xref rid="B35" ref-type="bibr">Cognato et al. 2005</xref>
; <xref rid="B70" ref-type="bibr">Jordal and Hewitt 2004</xref>
). Several relationships found in this phylogeny did not agree with the topologies obtained from different analyses. For example a hardwood-feeder, <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
<named-content content-type="species">rugulosus</named-content>

<named-content content-type="species">ventralis</named-content>

was found to be sister to the Nearctic conifer clade. In addition, the hardwood clade was paraphyletic with <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
<named-content content-type="species">fagi</named-content>

<named-content content-type="species">multistriatus</named-content>
</named-content>
</italic>
. Saturation of nucleotide substitutions and a lack of lineage sorting are potential reasons for the discordance among these mitochondrial and nuclear phylogenies (<xref rid="B124" ref-type="bibr">Sota and Vogler 2001</xref>
; <xref rid="B50" ref-type="bibr">Funk and Ohmland 2003</xref>
; <xref rid="B88" ref-type="bibr">Lin and Danforth 2004</xref>
). The mitochondrial phylogeny may suffer from both phenomena because of the observed poor resolution and support for deeper nodes and short-branch lengths among the conifer-feeding species (Fig. <xref ref-type="fig" rid="F3">3</xref>
). As with other studies, concatenating the COI dataset with multiple genes and morphology remedied its deficiency and elucidated the relationships among the <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>

species (<xref rid="B70" ref-type="bibr">Jordal and Hewitt 2004</xref>

<p>When analyzed together, the genes used in this study (COI, 28S, CAD, ArgK) were useful in resolving the <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
</named-content>

phylogeny and species limits. These genes have demonstrated similar phylogenetic utility in other scolytine studies (<xref rid="B33" ref-type="bibr">Cognato and Sperling 2000</xref>

). Overall, the model-based rates of nucleotide evolution utilized in Bayesian analysis combined with all four genes and morphology allowed us to recover a well-supported and sufficiently resolved phylogeny which enabled the revision of <italic><named-content content-type="taxon-name"><named-content content-type="genus">Scolytus</named-content>
