DESCRIPTION OF THREE NEW SPECIES OF THE FAMILY ANTHOIMYIIDAE FROM SICHUAN, CHINA (DIPTERA)

In the col1ection obteined from Mt. Emeiin recent years, three Anthomyiid speciesnew to science have been found. The typespecimens are kept in the Laboratory ofParasitology, West China University ofMedical Sciences. 1.Meliniella strigilliformis sp. nov.(Figs1-4) :Body length 6.5 mm. Body polishblack with fuscous pollen and entirely blackiegs, closely related to Meliniella miyazakiiSuwa, 1974, however, the new species isdistinguishable from the latter by havingthe lateral caudal margin of 9th tergite ex-tending downwards as a process, whichfringed with some brush hairs, and cercalplate neither quadrate, nor forked apically,surstylus bent forwards, 5th sternite withan appendix on the inner margin of itslateral lobe. Holotype, Jinding, Mt. Emei, April,1982, coll. Deng Anxiao. 2.Pegohylemyia hemiliocerca sp. nov.(Figs 5-8) : Body length 6 mm. Closely relatedto Pegohylemyia himalaica Suwa, 1977, butthe posterior margin of surstylus withsome small satulae in the middle part,anal cercal plate cardiformed, postgonitewith 1 long and 2 short setulae. Holotype, Leidongpin, Mt. Emei,June, 1983, paratype 2 , Jinding, June.1983, Leidongpin, June, 1984, coll. DengAnxiao, Zhu Shenghua. 3.Pegohylemyia sicyocerca sp. nov.(Figs 9-12) : Body length 4 mm. The presentnew species has some peculiar features interminalia: anal cercal plate in a reversedbottle-shape in caudal view, surstylus flat-tened in apical part and truncated at tip,pregonite bears leaflike seta, postgonitewith no hairs, by which it seemsto be somewhat resembling Pegohylemyiakitayamae, but by the other aspects of maleterminalia, they are very different fromeach other. Holotype, Leidongpin, Mt. Emei.June, 1984, paratype 6, same locality,June, 1980-1984, coll, Deng Anxiao.
