Other notable publications.

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).
