Genus Pterocryptus Szépligeti, 1916

Pterocryptus Szépligeti, 1916: 250 . Type species: Pterocryptus niger Szépligeti, 1916 . Monobasic.

In Japan, a single species, P. uchidai (Momoi, 1963) has been recorded. I examined the holotype and additional specimens of Torbda takachihoensis Momoi, 1966 , and concluded that this species should be transferred from Torbda to Pterocryptus . The character states of this species are completely accorded with the generic character states of Pterocryptus proposed by Townes (1970) and Gupta & Gupta (1983), e.g., pleural carina of propodeum present between anterior transverse carina and hind coxa ( Fig. 2B ) (absent in Torbda ) and T1 without a pair of triangular teeth at base ( Fig. 2G ). In this study, I transferred generic position of this species below.
