摘要：

Sinocyclocheilus is a group of cyprinid fishes endemic to China distributed in the karst region of southwest China. In this study, the complete mitogenomes of Sinocyclocheilus guilinensis Ji, 1985 and Sinocyclocheilus huangtianensis Zhu et al. 2011 are reported and characterized. Both genomes contain 13 protein-coding genes, 22 tRNAs, 2 rRNAs, and a non-coding control region, with lengths of 16,576 bp and 16,578 bp, respectively. Phylogenetic analysis shows that S. guilinensis is the earliest branching species in the S. jii group, while S. huangtianensis and S. jii are sister groups. These mitochondrial genomes are valuable for studying systematics of Sinocyclocheilus.
