The tribe Coenosiini has 9 genera in China, among them Coenosia and Lispocephala are two bigger ones. The former has 128 species and the. latter has 48 species. Recently many papers have reported species in Coenosiini, even some were embodied by SCI. Because some Chinese researchers don't have enough references, specimens or the acquaintance of variantion between species, it is difficult to avoid the mistakes of synonym and homonym in some species of the tribe Coenosiini. During the study supported by National Natural Science Foundation of China( No. 30870330, 31172139) , we find that some species of Coenosia and lispocephala in Leigongshan Landscape ( Diptera) are new synonyms. According by external and terminalia features, 20 species have been corrected herein, including 8 species of Coenosia and 12 species of Lispocephala.%中国秽蝇族共有9个属、其中秽蝇属种类128种,溜头秽蝇属种类48种,分别是秽蝇族中较大的属.近年来中国各地报告秽蝇族种类很多,多在国外SCI刊物发表,国内学者在文献资料不全、标本较少和对种群个体变异认知不足的情况下,在发表的秽蝇族种类中很难避免出现同物异名或异物同名等同题.在完成国家自然科学基金项目的过程中,发现了《雷公山景观昆虫》专著中的秽蝇属和溜头秽蝇属的部分种类存在一些问题,其中秽蝇属8个种和溜头秽蝇属的12个种存在同物异名的次异名,共20种,根据外部和尾器形态特征相结合的方法分别作了订正.
