Pachynomidae是一个知之甚少的异翅目类群，目前被认为是与Reduviidae密切相关的一个独立的科。厚角蝇科的分类地位长期以来一直存在争议。对该家族线粒体基因组的了解也很有限。在本研究中，我们描述了完整的有丝分裂基因组Camarochiloides weiweii，第一个有丝分裂基因组测序为这个家庭。该有丝分裂基因组由13个蛋白质编码基因、2个rRNA基因和21个tRNA基因组成。在该基因组中观察到两种tRNA基因重排，包括trnA和trnR的易位以及trnH的易位，并且可以用串联重复随机丢失（TDRL）模型来解释。基于三个不同的有丝分裂基因组数据集序列的贝叶斯和最大似然分析恢复了Reduvioidea的单系性，以及Reduvioidea和其余Cimicomorpha谱系之间的姐妹关系。本研究为进一步利用大规模采样的丝裂基因组数据进行升麻属系统发育研究提供了参考。(C)2020 Elsevier B.V.保留所有权利。
Pachynomidae is a poorly known heteropteran group currently considered as a distinct family closely related to Reduviidae. Taxonomic position of Pachynomidae has been debated for a long time. Knowledge aboutmitochondrial genome (mitogenome) of this family also remain limited. In the present study, we describe the complete mitogenome of Camarochiloides weiweii, the first mitogenome sequenced for this family. This mitogenome consists of 13 protein-coding genes, two rRNA genes and 21 tRNA genes. Two tRNA gene rearrangements in this genome, including the translocation of trnA and trnR as well as the transposition of trnH, were observed and could be explained by the tandem duplication-randomloss (TDRL) model. Bayesian andmaximumlikelihood analyses based on sequences of three different mitogenomic datasets recovered the monophyly of Reduvioidea, and the sister relationship between Reduvioidea and the remaining Cimicomorpha lineages. This study enlightens the future application of mitogenomic data in the phylogenetic study of Cimicomorpha based on the large-scale sampling. (C) 2020 Elsevier B.V. All rights reserved.
