Abstract
The Diclybothriidae (Monogenoidea: Oligonchoinea) includes specific parasites of fishes assigned to the ancient order Acipenseriformes. Phylogeny of the Diclybothriidae is still unclear despite several systematic studies based on morphological characters. Together with the closely related Hexabothriidae represented by parasites of sharks and ray-fishes, the position of Diclybothriidae in different taxonomical systems has been matter of discussion. Here, we present the first molecular data on Diclybothriidae. The SSU rRNA gene was used to investigate the phylogenetic position of Paradiclybothrium pacificum and Diclybothrium armatum among the other Oligonchoinea. Complete nucleotide sequences of P. pacificum and D. armatum demonstrated high identity (98.53%) with no intraspecific sequence variability. Specimens of D. armatum were obtained from different hosts (Acipenser schrenckii and Huso dauricus); however, variation by host was not detected. The sequence divergence and phylogenetic trees data show that Diclybothriidae and Hexabothriidae are more closely related to each other than with other representatives of Oligonchoinea.
