Complete mitochondrial genome of Colias sifanica Grum-Grshimailo, 1891 (Lepidoptera: Pieridae) from montane region in northwestern China

Grum-Grshimailo, 1891, is a typical montane butterfly species which occurs on the Qinghai-Tibet Plateau (QTP) and adjacent regions in China. In this study, the complete mitochondrial genome of this species was assembled from data generated by next-generation sequencing. The mitogenome was 15,151 bp in length and comprised 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, 22 transfer RNA genes and a control region. The base composition of the mitogenome was 39.7% A, 41.3% T, 11.3% C and 7.7% G, significantly AT biased as commonly found in other Pieridae mitogenomes. Phylogenetic analyses based on all PCGs using both the maximum likelihood and Bayesian inference methods indicated that is closely related to with high support values, and the phylogenetic relationship of ( + (( + ) + ( + ( + ( + ( + ))) was shown for the tribe Coliadini. Though both the mitogenomic gene order and overall base composition were found to be conserved, different Ka/Ks ratios for several mitogenomic PCGs were detected between and other species in the tribe Coliadini.
