Catalogue and Bibliography of the Hong Kong Carabidae Latreille, 1802 (Coleoptera: Adephaga), with notes on the historic boundaries of Hong Kong as related to zoological collections Author Aston, Paul text Zootaxa 2016 4121 3 201 257 journal article 38912 10.11646/zootaxa.4121.3.1 6cb37831-da16-4763-a32c-aef636512990 1175-5326 265007 172021D4-55C8-483F-A6B2-F823C3022F90 Subgenus Tachys Six specimens surely correspond to this subgenus but could not be identified to species. These are quite distinctive in having the elytra, pronotum and head all black. I have collected other beetles of genus Tachys that possibly correspond to three different species, but it was not possible to even key them to a particular subgenus.
