Peer Review Report For: The complete mitochondrial genome Hainan Gymnure, Neohylomys hainanensis [version 2; peer review: 3 approved]

The Hainan Gymnure Neohylomys hainanensis is a small-size mammal which occurs in Hainan, China and north Vietnam. Here, we report the complete mitochondrial genome of N. hainanensis. The whole mitochondrial genome is 17,337 bp, and contains 13 protein-coding genes, 22 tRNAs, 2 rRNAs and one control region. The base composition of the N. hainanensis total mitogenome is: 33.4% A, 12.2% G, 33.1% T, and C 21.3%, with an A + T content of 66.5%. The K2P genetic distance analysis supports current taxonomy that places N. hainanensis , Hylomys suillus and Neotetracus sinensis in different genera. Phylogenetic analysis suggests that N . hainanensis is closely related to Neotetracus sinensis based on the complete mitochondrial genome sequences. The mitogenomic data will contribute to molecular phylogenetics and conservation genetics of the species.
