Genus Hedycryptus Cameron, 1903

Hedycryptus Cameron, 1903a: 298 . Type species: Hedycryptus filicornis Cameron, 1903 (= Cryptus orientalis Cameron, 1897). Monobasic.

Apachia Townes, 1970: 195 . Type species: Cryptus tenuiabdominalis Uchida, 1930 . Original designation.

In Japan, a single species, H. tenuiabdominalis (Uchida, 1930) has been recorded. This genus apparently resembles Cryptus and can be separable by the following combination of character states: petiole of T1 with terete, without longitudinal carina (Figs. 2L, M) (with ventrolateral (and in female also dorsolateral) longitudinal carina(e) in Cryptus: Figs. 2I–K); second recurrent vein usually simply arched (Fig. 1J) (usually weakly sinuate in Cryptus); front side of areolet quite narrow (moderately wide to narrow in Cryptus); T2 covered with rather sparse to rather dense (Fig. 8F) setae in female (covered with rather to very sparse setae in female of Cryptus) (Townes, 1970). I examined the holotype and additional specimens of Cryptus ohshimensis Uchida, 1930, and recognized that the character states of this species are completely accorded with the generic character states of Hedycryptus . Thus, I concluded that this species should be transferred from Cryptus to Hedycryptus . In this study, I transferred generic position of this species with redescription below.
