摘要：

This study aimed to sequence and annotate the complete mitochondrial DNA genome sequence of Opsarius pulchellus. Complete mitochondrial genome is a circular molecule of 16,552 bp in length, including 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and a displacement loop region. Proportion of nucleotides in mitochondrial genome is 26.8% T, 26.9% C, 27.6% A, and 18.8% G, with an AT bias of 54.4%. Maximum-likelihood phylogenetic tree was reconstructed using the connected protein sequences of 13 PCGs of O. pulchellus and other 18 fishes. Result of phylogenetic analysis supports a close relationship between O. pulchellus and Barilius bendelisis (Hamilton, 1807). Fundamental genetic data of O. pulchellus would be beneficial for further studies on genetic diversity and phylogeny.
