The complete mitochondrial genome of (Teleostei, Cypriniformes) in Lantsang River and its phylogenetic analysis.

is a small-sized benthopelagic fish species in the family Nemacheilidae, superfamily Cobitidea. In this study, the entire mitogenome sequence of the has been sequenced by using sanger sequencing method. The circular mitochondrial genome was 16,570 bp in length and contained of 13 protein-coding genes, two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, an origin of light-strand replication (OL), and one displacement loop locus (D-loop). The overall base composition was 30.1% A, 26.4% T, 26.8% C, and 16.7% G with 56.6% AT content. Most genes were encoded on the heavy strand except for ND6 and eight tRNA genes. There were 11 regions of gene overlaps totaling 29 bp and 7 intergenic spacer regions totaling 37 bp. Its structure type was similar to the mitogenome of Cobitidea fishes. Phylogenetic analysis with 33 complete mitogenomes of Cobitidea and fishes in the family of Mastacembelidae suggested that species clustered as one monophyletic clade and was closely related to Mitogenome information from this study could be a useful basis for conservation and phylogenetics of this species.
