Characterization of the complete mitochondrial genome of the snow crane-fly Chionea crassipes gracilistyla (Diptera Tipuloidea Limoniidae) with phylogenetic analysis

摘要

The genus Chionea Dalman, 1816 is a peculiar group of crane flies with extremely short wings. In this study, we report the first complete mitochondrial (mt) genome sequence of the genus Chionea, which is a circular molecule of 15,775 bp with an AT content of 76.9% and contains 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a long non-coding region. Phylogenetic analysis revealed that the Pediciidae was sister-group to the remaining Tipuloidea and strongly supported the sister-group relationship between Cylindrotomidae and Tipulidae.
