摘　　要：线粒体基因组已广泛应用于许多昆虫类群的系统发育研究。GenBank中只有1个完整的扁角菌蚊科线粒体基因组,属于织网菌蚊亚科。在此,我们公布了扁角菌蚊科另1个亚科--扁角菌蚊亚科的第1个线粒体基因组,它是1个15,521 bp的环状分子,AT含量为78.9%。该线粒体基因组包含13个蛋白质编码基因、22个转运RNA基因、两个核糖体RNA基因和一个控制区。除控制区外,扁角菌蚊亚科的Orfeliasp.线粒体基因组的整体和各部分的AT含量均高于织网菌蚊亚科的Arachnocampa flava Harrison, 1966。核苷酸替代率(dN/dS)分析表明,扁角菌蚊科线粒体基因组中ND5基因的进化速度最快,而COI基因的进化速度最慢。Mitochondrial(mt)genomes have been widely used in the phylogenetic study of many insect groups.There is only one complete mt genome of a member of the family Keroplatidae available in GenBank and it belongs to the subfamily Arachnocampinae.Here,we report the first mt genome of a member of the subfamily Keroplatinae in the family Keroplatidae.It is a circular molecule of 15,521 bp with an AT content of 78.9%.This mt genome contains 13 protein coding genes(PCGs),22 transfer RNA genes(tRNAs),two ribosomal RNA genes(rRNAs)and a control region.The AT content of the whole and each part of this mt genome of Keroplatinae(Orfelia sp.)are higher than that in Arachnocampinae(Arachnocampa flava Harrison,1966),except for the control region.The ratio(dN/dS)among Keroplatidae flies shows that ND5 has the fastest evolutionary rate,while COI has the slowest evolutionary rate.
