摘要

Two new species Mirostylochus striatus and M. sachalinensis from the Sea of Japan and the Sachalin island coast are described. This is the first finding of the genus Mirostylochus in Russian fauna. The taxonomic revision of Mirostylochus was performed on the basis of morphological analyses of the new species. As a result, the diagnostic characteristics of the genus and species are defined more accurately.
