摘要：

Sinocyclocheilus oxycephalus is a freshwater cyprinid fish of high nutritional value, endemic to Shilin County, Southwestern China. In this study, we first sequenced the complete mitochondrial genome (mitogenome) of S. oxycephalus. The whole length of mitogenome is 16,585 bp, which contains 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and a control region. The gene arrangement and structure is identical to other previously reported Sinocyclocheilus fishes. The overall base composition is 31.26% A, 16.42% G, 25.41% T and 26.90% C, with AT content of 56.67%. Phylogenetic analysis using mitogenomes of 13 cyprinid fishes showed that S. oxycephalus are closely related to S. anophthalmus, S. grahami, and S. wumengshanensis, and 11 Sinocyclocheilus species are grouped as a monophyletic Glade with strong supports.
