下石棺的形态，习惯和地理分布非常多样化，通常被认为具有重要的生态，医学和法医意义。在本研究中，首次获得了18个线粒体基因组（有丝分裂基因组）。基因的重排和方向与祖先昆虫相同。数据集中的组成异质性程度极低。此外，在纯化选择下，有13个蛋白质编码基因正在发展。强烈支持了属群体类群boettcheria +（peckia +（ravinia + acysarcodexia））的系统发育关系）。除了多形的副帕拉西加外，还以单属菌（Liopygia，liosarcophaga，pierretia，pierretia，杂种）的形式回收了四个亚属。 S. dux和S. egyptiaca，S。pingi和S. kawayuensis之间的姐妹关系分别被发现了。此外，很少在这项研究之前提出了亚属Helicophagella，Kozlovea，Kozlovea，Kramerea，Pandelleisca，Pandelleisca，Phallocheira，Pseudothyrsocnema，Sinonipponia和Senior Whitea的分子发育关系。这项研究提供了对亚科石棺的种群遗传学，分子生物学和系统发育的见解，尤其是对于石棺的亚类分类。然而，与肉蝇的巨大物种多样性相比，可用的有丝分裂组仍然受到恢复石棺的系统发育的限制。 （c）2020 Elsevier B.V.保留所有权利。
The subfamily Sarcophaginae is extremely diverse in morphology, habit and geographical distribution, and usually considered to be of significant ecological, medical, and forensic significance. In the present study, 18 mitochondrial genomes (mitogenomes) of sarcophagid flies were first obtained. The rearrangement and orientation of genes were identical with that of ancestral insects. The degrees of compositional heterogeneity in the datasets were extremely low. Furthermore, 13 protein-coding genes were evolving under purifying selection. The phylogenic relationship of the genus-group taxa Boettcheria + (Sarcophaga + (Peckia + (Ravinia + Oxysarcodexia))) was strongly supported. Four subgenera were recovered as monophyletic (Liopygia, Liosarcophaga, Pierretia, Heteronychia) in addition to Parasarcophaga as polyphyletic. The sister relationships between S. dux and S. aegyptiaca, S. pingi and S. kawayuensis were recovered, respectively. Moreover, the molecular phylogenetic relationships among the subgenera Helicophagella, Kozlovea, Kramerea, Pandelleisca, Phallocheira, Pseudothyrsocnema, Sinonipponia and Seniorwhitea were rarely put forward prior to this study. This study provides insight into the population genetics, molecular biology, and phylogeny for the subfamily Sarcophaginae, especially for the subgeneric classification of Sarcophaga. However, compared with the enormous species diversity of flesh flies, the available mitogenomes are still limited for recovering the phylogeny of Sarcophaginae. (C) 2020 Elsevier B.V.
