Abstract(cid:1) Three new speciesof thegenusHypopygiopsis Townsend, 1916 (Diptera, Calliphoridae), namely, H. yunnanensis
sp. nov., H. dactylis sp. nov. andH. diversis sp. nov., are described and illustrated from Yunnan, SouthwesternChina. A
key to theknown speciesofHypopygiopsis isprovided, and bothH. fumipennis(cid:1)groupandH. violacea(cid:1)group are setup. The type
