为了提高我们对石棺亚科物种和属之间系统发育关系的了解，我们分析了三个线粒体基因片段的数据。细胞色素氧化酶 I (COI)、细胞色素氧化酶 II (COII) 和脱氢酶亚基 4 (ND4) 基因部分的序列数据从代表 15 个属的 43 种石蝇科中获得。我们使用贝叶斯方法来同时选择如何最好地对数据进行分区以及对每个分区应用哪种替代模型。使用贝叶斯推理和最大似然方法推断系统发育关系。我们的结果与 Sarcophaginae 亚科的单系性一致（后验概率 1；bootstrap 支持 93%），以及 Sarcophaginae 内几个属的单系性（包括 Sarcophaga s.l.；后验概率 1；bootstrap 支持 97%）。我们发现了对 Ravinia Robineau-Desvoidy 和 Oxysarcodexia Townsend 之间姐妹群关系的支持，这是过去的作者根据形态相似性假设的，尽管这仅在贝叶斯分析（后验概率 0. 81-0. 98）和一些新的超属分支中得到支持。与最近的形态学假设相反，我们没有发现 Helicobia Coquillett 嵌套在 Sarcophaga Meigen 中；我们的数据表明，但并不强烈支持佩克氏罗宾诺-德斯沃蒂（Peckia Robineau-Desvoidy）是石棺纲的姐妹群的假设。
In an effort to improve our knowledge of the phylogenetic relationships among species and genera of the subfamily Sarcophaginae, we analysed data from three mitochondrial gene fragments. Sequence data for portions of the genes cytochrome oxidase I (COI), cytochrome oxidase II (COII) and dehydrogenase subunit 4 (ND4) were obtained from 43 species of Sarcophagidae representing 15 genera. We used a Bayesian approach to simultaneously choose how best to partition the data and which substitution model to apply to each partition. Phylogenetic relationships were inferred using Bayesian Inference and Maximum Likelihood methods. Our results are consistent with monophyly of the subfamily Sarcophaginae (posterior probability 1; bootstrap support 93%), as well as with monophyly of several genera within the Sarcophaginae (including Sarcophaga s.l.; posterior probability 1; bootstrap support 97%). We found support for a sister‐group relationship between Ravinia Robineau‐Desvoidy and Oxysarcodexia Townsend, which has been hypothesised by past authors on the basis of morphological similarities, although this was supported only in the Bayesian analyses (posterior probability 0. 81–0. 98), and for some novel supra‐generic clades. Contrary to a recent morphological hypothesis, we do not find Helicobia Coquillett to be nested within Sarcophaga Meigen; our data suggest, but do not strongly support, a hypothesis that Peckia Robineau‐Desvoidy is the sister group to Sarcophaga.
