Mitochondrial genomic characterization of two endemic Chinese freshwater crabs of the genus Sinopotamon (Brachyura: Potamidae) and implications for biogeography analysis of Potamidae.

ABSTRACT: As an endemic freshwater crab group in China, the phylogenetic relationships within Sinopotamon are still controversial because of the limited taxon samples. In this study, the complete mitogenomes of Sinopotamon chishuiense with 17,311 bp and the nearly complete mitogenomes of S. wushanense with 16,785 bp were firstly sequenced and analyzed. Compared with other reported mitogenomes of Potamidae, some novel patterns of gene rearrangement were detected in these two Sinopotamon mitogenomes, which could be illuminated by the mechanisms of tandem duplication-random loss, recombination, and translocation. Phylogenetic analyses showed the nonmonophyly of the Sinopotamon and a sister group relationship with Tenuilapotamon. These crabs from the eastern and
