Freshwater crabs play essential roles in the well-functioning of the inland aquatic ecosystems. However, due to the lack of sufficient molecular resources, the study of freshwater crabs has been greatly hindered. In this study, the mitochondrial genome of Huananpotamon koatenense, a freshwater crab endemic to China, was sequenced for the first time. This mitogenome sequence is 15,528 bp long, and contains 13 protein-coding genes, 2 rRNA genes and 22 tRNA genes. Phylogenetic analyses based on 25 mitogenomes showed that H. koatenense was clustered with the known congeneric species of H. lichuanense. [ABSTRACT FROM AUTHOR]

We sequenced the complete mitochondrial genome of the San Lucan gecko, Phyllodactylus unctus, which is endemic to Mexico. The complete mitochondrial genome was 16,881 bp in size, consisting of 37 genes coding for 13 proteins, 2 rRNAs, 22 tRNAs and 1 control region. Its gene arrangement pattern was identical with most vertebrates. We compared the mitochondrial genome of P. unctus with that of the Moorish gecko, Tarentola mauritanica, which is the only other sequenced species from Phyllodactylidae. Nucleotide sequence divergence ( p distance) between two mitochondrial genomes was 31.32%. The detailed comparison between the mitochondrial genomes of two species was done. [ABSTRACT FROM AUTHOR]
