摘要
基于形态学和分子遗传学证据,描述了冠果蝇属1新种Stegana(Stegana)helvipecta sp.nov.和2中国新记录种:S.(S.)furta(Linnaeus,1767)和S.(S.)taba Okada,1971;利用41条DNA条形码信息,分析了18种冠果蝇的遗传距离,并提供了中国产全部18种冠果蝇的形态图及分种检索表。
One new and two known species of the subgenus Stegana(s.str.)from China are described or redescribed:S.(S.)helvipecta sp.nov.,S.(S.)furta(Linnaeus,1767)and S.(S.)taba Okada,1971.A total of 41 DNA sequences of partial mitochondrial cytochrome c oxidase subunit I(COI)gene of 18 species of this subgenus are newly obtained in this study.These sequences along with other available barcoding sequences for this subgenus are incorporated in a molecular analysis using the neighbor-joining(NJ)method in order to assess the efficacy of DNA barcoding for delimiting these species.Habitus and a key to all Chinese Stegana(s.str.)species are provided.
