Hind second tarsomere 5.0 × as maximum depth. Tarsal claws simple. Metasoma. T I 1.4–1.5 × as long as maximum width.
Coloration (Figs 7 A, B). Similar to female. Tegula and wing base yellow. Basal part of tibiae paler than female. T III and T IV reddish brown to red.
Distribution. Japan (Hokkaido and Honshu). Outside Japan, this species has been recorded from Russia, China and Korea (Yu et al. 2016; Kang et al. 2020).
