Genus Hoplocryptus Thomson, 1873

Hoplocryptus Thomson, 1873: 472, 508. Type species: Hoplocryptus binotatula Thomson, 1873 (= Cryptus fugitivus Gravenhorst, 1829). Designated by Viereck (1914).

Six species, Ho. alboanalis (Uchida, 1952), Ho. ohgushii (Momoi, 1963), Ho. pini (Momoi, 1973), Ho. scorteus (Momoi, 1968), Ho. sugiharai Uchida, 1936 and Ho. sumiyona Uchida, 1956, have been recorded from Japan. Recently Wang et al. (2019b) provided a key to the species of this genus known from the Oriental and Eastern Palaearctic regions. I herein describe six new species, Ho. ashoroensis sp. nov., Ho. ezoensis sp. nov., Ho. intermedius sp. nov., Ho. japonicus sp. nov., Ho. maculatus sp. nov. and Ho. toshimensis sp. nov., from Japan. In addition, I redescribe Ho. pini with a new description of male and record Ho. sumiyona from Tokunoshima Island for the first time below.
