Abstract(cid:1) Twonew speciesof the genusLasiopeltaMalloch, 1928 (Diptera, Muscidae), namely, L. rufescentaWeiet Jiang,
sp. nov. andL. flava Weiet Cao, sp. nov., are described and illustrated from Guizhou, Southwestern China. A key to
known speciesof the genus isprovided andLasiopeltamaculipennis(cid:1)group is setup. The type specimensof the new speciesare
kept in theCentre forDisease Prevention and ControlofAnshunCity, Guizhou (CDPCAG).
