Description. See Momoi (1968) and Schwarz (1990).

Distribution. Japan (Hokkaido and Honshu).

Bionomics. Host: Eumenes samuray Schulthess, 1908 (= Eumenes rubronotatus rubronotatus Pérez, 1905 ) ( Hymenoptera , Vespidae ) ( Momoi, 1968).

Remarks. No particular morphological differences were found between European and Japanese specimens. In Japan, males of Nippocryptus are extremely underrepresented compared to females. Such a tendency was also observed in this species. Japanese name of this species, “Kuro-Shikoku-togari-himebachi” is based on the black-bodied species resembles “Shikoku-togarihimebachi”, Caenocryptus shikokuensis (Uchida, 1936) , while the generic positions of both species are different each other and this species has no distribution data from Shikoku. Thus, I propose new SJN based on Dr. Setsuya Momoi in this study.
