An octannulate Orobdella leech, Orobdella octonaria Oka, 1895, is redescribed on the basis of one syntype collected from Hakone, Kanagawa Prefecture, Japan, and two newly obtained specimens, also from Hakone. It is distinguished from the other known species of Orobdella by its octannulate mid-body somites. No holotype of this species was originally designated. The present syntype from Hakone is designated as the lectotype of O. octonaria for the purpose of clarifying its taxonomic status and type locality.
