The genus Meigen, 1803 is the largest genus of the family Ptychopteridae with 78 known species. In this study, we report a nearly complete mitochondrial (mt) genome of this genus, which is a circular molecule of more than 15,028 bp. The mt genome contains 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and a non-coding region. The overall base composition is A (38.1%), T (36.7%), C (14.9%), and G (10.4%), with an AT content of 74.8%. The AT content of N-strand genes (75.7%) is higher than that of the J-strand genes (71.7%). Phylogenetic analysis reveals that the monophyly of Ptychopteridae, Bibiomorpha, Tipulomorpha and Brachycera are strongly supported, and the sister group relationship between Tanyderidae and Ptychopteridae is not supported.
梅根属(Meigen,1803)是大蚊科中最大的属,已知有78个物种。在本研究中,我们报道了该属一个近乎完整的线粒体(mt)基因组,它是一个超过15,028 bp的环状分子。该线粒体基因组包含13个蛋白质编码基因、22个tRNA基因、2个rRNA基因和一个非编码区。总体碱基组成为A(38.1%)、T(36.7%)、C(14.9%)和G(10.4%),AT含量为74.8%。N链基因的AT含量(75.7%)高于J链基因(71.7%)。系统发育分析表明,大蚊科、比氏蚊亚科、大蚊亚科和短角亚目的单系性得到了有力支持,而大蚊科与沼大蚊科之间的姐妹群关系未得到支持。
