Abstract

The Barbodes hexagonolepis, as an important commercial species, had the limited resources on biology and genetics. We reported the complete mitogenome of this species, and got a whole length of 16 587 bp (containing two rRNAs, 22 tRNAs, 13 mRNAs and one D-loop region). The two rRNAs located between tRNA^phe and tRNA^leu and were separated by tRNA^val. The 22 tRNAs was ranged from 66 bp (tRNA^cys) to 76 bp (tRNA^leu and tRNA^lys) in length. The 13 mRNAs had four overlap regions, three types of start codons and four types of termination codons. The D-loop region was found between tRNA^Pro and tRNA^Phe. To further explore the phylogenetic relationship of the B. hexagonolepis, we constructed the phylogenetic tree and verified that the B. hexagonolepi was a part of the Barbinae and independent from other genus of the Barbinae. This result provided the valuable evidence on phylogenetic relationship of the B. hexagonolepi at the molecular level and essential resource for further research on this species.
