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

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.
