The type specimens are kept in the author’s laboratory. Supported by National Natural Science Fundation. 1 Pegohylemyia papiliocera sp. nov. (Figs. 1-3) Body length 4 mm. Basing on the cereal plate widened at apex and postgonite with a pair of membranous bristles, the new species is more or less related to Pegohylemyia bre- vipalpis Jin. but differs from the latter in ori 7 pairs, 3rd antennal segment about 1.2 times as long as its width, epistoma protruding slightly, surstyli bent backwards and cereal plate alarily broadened and with 5 tubercles on apical margin. Holotype , Locality: Sanlong of Maowen County, June 14, 1989,paratypes 7, coll. by DENG An-xiao. 2 Pegohylemyia alcaecerca sp. nov. (Figs 4-6) ,Body length 4 mm. The new species resembles Pegohylemyia papiliocerca as above mentioned, but differs from the latter in surstyli straight, cereal plate not alanly broadened, only with one median prominence at apex,and its length longer than its width covers behind the surstyli when seen in caudal view. Holotype,Locality: Sanlong of Maowen County, paratypes 2 , June 21, 1988, coil. by DENG An-xiao. 3 Pegohylemyia cornuta sp. nov. (Figs 7-9) ,Body length 4 mm. The new species resembles Pegohylemyia kitayamae Suwa in Japan,but differs from the latter by in on 3rd antennal segment about twice as long as its width, 5th sternite with short and dense bristles on the inner side of arms,bristles on prego- nite in orchid leaf-shaped, and the posterior margin of surstylus arc-shaped in profile. 4 Pegohylemyia tetracrala sp. nov. (Figs. 10-12) ,Body length 6 mm. The new species is related to Pegohylemyia rubrigena Schnabl, but differs from the latter by having 3 rows of up-curved peristomal setae, upper calypteron larger than lower one, cereal plate consists of 4 medial apices among them, the inner pair di- vergent and the outer pair convergent, and lateral margin of cerci being wavy, anterior mar- gin of surstyli do not swo
