Complete mitochondrial genome of Eonemachilus longidorsalis (Cypriniformes: Nemacheilidae): genome characterization and phylogenetic consideration

Abstract

For the first time, this study presents the complete mitochondrial genome and phylogenetic analysis of Eonemachilus longidorsalis , an endemic species in southwest China. The mitogenome is a circular molecule of 16,569 bp in length with a base composition of 30.2% A, 27.3% T, 16.6% G, and 25.9% C. The phylogenetic analysis based on the complete mitogenomes shows that E. Longidorsalis clusters with Yunnanilus jiuchiensis , Yunnanilus pleurotaenia and Eonemachilus niger. This contribution may provide a valuable framework for completely resolving phylogenetic relationships of the family Nemacheilidae in future research.
