The genus Dirrhagofarsus Fleutiaux, 1935 is firstly reported from Korea with three species, Dirrhagofarsus lewisi (Fleutiaux,1900), D. modestus (Fleutiaux, 1923), and D. unicolor (Hismatsu, 1960). Among them, D. unicolor was described asa ‘form(=f.)’ of D. modestus by Hismatsu (1960). In this study, we re-establish the status of this species as proper species,Dirrhagofarsus unicolor. We provided a key to Korean Dirrhagofarsus species, diagnoses, and photographs for each species.
