Priocnemis mitakensis Ishikawa: Kim, 1970: Pl. 55, Fig. 656 (Ş, Korea: GN: Gayasan), 806, as new to Korea. Misidentification.

Voucher specimen. Ş, Mt. Gayasan, 1960.v.8 / Hy. 44, 27 - 6.

Distribution. Korea (GG, GN, JJ), China (Henan, Jiangxi, Zhejiang), Russian Far East (Primorsky Territory, Khabarovsk Territory, Amur Region, South Sakhalin, Kuril Islands: Kunashir), Japan (from Hokkaido in the north to Yakushima in the south), and Taiwan.

Notes. Kim (1970) was the only record for Priocnemis mitakensis in Korea, because later records of this species for the Korean fauna by Lelej et al. (1994) and Loktionov and Lelej (2014) were the mere citations of him. As this species is a misidentification of Caliadurgus ussuriensis as mentioned above, there has been no formally recognized Korean material of P. mitakensis . At present, it is reasonable that P. matakensis should be excluded from the Korean fauna although it is broadly found in surrounding areas of the Korean Peninsula.

Caliadurgus ussuriensis was first recorded in Korea by Lelej et al. (1994). In the Far East, the genus Caliadurgus are easily separated from the other Pepsinae genera by the following combination of characteristics. In both sexes, vertical anterior face of pronotum that are well demarcat- ed from horizontal face ( Fig. 1A , red arrow); in females, a long triangular rigid spine at the dorsoapical margin of fore tibia medially ( Fig. 1B , black arrow); in males, whit- ish meso- and metatibial spurs. Females of this species is entirely black, with long and slender flagellomere 1 (5.2 - 6.3 × as long as broad).
