SarcophagaMeigen是一种种类繁多的真蝇属，全世界大约有850种。该属被分为大约160个亚属，其中绝大多数的有效性从未使用分支分类方法验证过。本文主要研究了古北大陆的HeteronychiaBrauer & Bergenstamm亚属，该亚属共有89种，是石甲亚基中最大的亚基。我们对该群体进行了分支分析，完全基于男性形态特征。对88种84个性状的矩阵进行简约性分析。DiscachaetaEnderlein亚属和NotoecusStein亚属的物种也包括在基质中。进一步的分析仅使用词尾词的一个字符子集（70个字符）进行。结果表明，由异甲目（Heteronychia）、异甲目（discahaeta）和Notoecus组成的支系是单系的，discahaeta是多系的，而Sarcophaga (Notoecus) longestylatastobl嵌套在Sarcophaga - filia群中。详细讨论了支持异甲目和少数支持良好的种群的性状状态。提出下列同义词：Discachaeta=Heteronychia（同义11月）和Notoecus=Heteronychia（同义11月）。本文还介绍了该分类单元的历史背景，与过去两个世纪以来石棺属的分类有关，以及对雄性终端的术语回顾，特别是双翅虫属。(c) 2013年伦敦林奈学会
SarcophagaMeigen is one of the megadiverse genera of true flies, with approximately 850 valid species worldwide. The genus is divided into about 160 subgenera, the validity of a vast majority of which has never been verified using cladistic methods. This paper deals with the mainly Palaearctic subgenus HeteronychiaBrauer & Bergenstamm, which comprises 89 species and is thus the largest subunit of Sarcophaga. We performed a cladistic analysis of the group based exclusively on male morphological characters. Parsimony analyses were run on a matrix of 84 characters for 88 species. Species of the subgenera DiscachaetaEnderlein and NotoecusStein were also included in the matrix. A further analysis was carried out using a subset of characters from the terminalia alone (70 characters). The results show that the clade formed by Heteronychia, Discachaeta, and Notoecus is monophyletic, with Discachaeta emerging as polyphyletic whereas Sarcophaga (Notoecus) longestylataStrobl is nested within the Sarcophaga filia-group. Character states supporting Heteronychia and the few well-supported species-groups are discussed in detail. The following synonymies are proposed: Discachaeta=Heteronychia (syn. nov.) and Notoecus=Heteronychia (syn. nov.). The paper also includes a historical background of the taxon in relation to the classification of the genus Sarcophaga over the past two centuries, as well as a terminological review of the male terminalia, particularly of the distiphallus.(c) 2013 The Linnean Society of London
