Oreolalax rhodostigmatus Hu and Fei, 1979 is a rare and threatened frog, which is mainly distributed in the caves or underground waters in karst regions of southwest China. The International Union for Conservation of Nature (2017) categorized this endemic species as vulnerable. In this study, we reported the first complete mitochondrial genome of O. rhodostigmatus. The circular double-strand genome was 18,676 bp in size and contained 13 proteincoding genes, 23 transfer RNA genes, 2 ribosomal RNA genes, and a putative control region. The overall nucleotide composition was: 28.0% A, 32.4% T, 24.9% C, and 14.7% G, with a total A+T content of 60.4%. The common genomic features including genome content, gene order, and composition were similar to those of other Oreolalax species. Phylogenetic analysis of 17 Megophryidae species indicated that O. rhodostigmatus was located in the basal clade of Oreolalax.
