Other notable publications. Bischoff 1930: 2 (placed in Triepeolus); Yasumatsu 1933: 3 (as E. japonicus, key, figures); Hirashima 1955: 41–42 (as E. japonicus, key); Rightmyer 2004: 251–256 (re-description, figures); Mitai in Tadauchi & Murao, 2014: 409 (as E. japonicus, descriptive note, figures).

Host (s). Unknown.

Remarks. Rightmyer (2004) re-described and illustrated the holotype of Epeolus tsushimensis . We analyzed the original description of E. japonicus Bischoff, 1930, descriptive notes for this species by Hirashima (1955), illustrations published by Mitai in Tadauchi & Murao (2014) and concluded that E. tsushimensis is conspecific with E. japonicus, syn. nov. This species distinguished from other Epeolus by follow combination: the body entirely black; labrum with two close submedial teeth, apical margin straight with distinct medial tooth, female with metasomal segments 4 and 5 much narrower than basal segments (pear-shaped metasoma).

Distribution. Japan (Tsushima) (Rightmyer 2004).
