Common Name

Ibari-ari
Language:	Japanese

This species is very rare. It has been collected only twice in Japan, from Masutomi-onsen, Yamanashi Prefecture (Nakano,1938), and Washu-zan, Okayama (not Hiroshima) Prefecture (Collingwood, 1976). Both were taken from nests of Tetramorium tsushimae. This species has long been known but nomenclaturally undetermined in Japan. Terayama (1988) recently identified it as S. koreanus Pisarski, originally described from the Korean Peninsula. There are only two Korean collection records, from Myohyang (the type locality) and Gumpongli-Saryangdo (Kim et al., 1989; Japanese Ant Image Database).
