摘要
The taxonomic status and relationships of the Askoldia, Pholidapus, and Opisthocentrus genera of the subfamily Opisthocentrinae are discussed based on comparative morphological and molecular genetic analysis. Isolation of the Pholidapus from the Opisthocentrus and the greater similarity of the former with the Askoldia were revealed. Morphological and genetic differences could not allow one to consider the Pholidapus as being within the Opisthocentrus. O. ocellatus and O. tenuis were closer within the Opisthocentrus and O. zonope was significantly different from these two species.
