The phylogenetic analysis of these two nonmarine crabs together with intertidal, supratidal and swimming crabs based on portions of mitochondrial 16s rdna sequences suggested that grapsioidea, ocypodoidea, potamoidea and portunoidea arose from a common marine ancestor, and the estimated divergence time are similar. the freshwater crab phylogeny suggested that the genus sinopotamon and the genus potamonautes arose from a common ancestor and the estimated divergence time is about 36 - 44 mya
基於線粒體16srdna部分序列，對這2個類型的非海洋蟹類與潮間帶蟹類、海洋蟹類之間的系統發生分析提示，方蟹總科（ grapsioidea ） 、沙蟹總科（ ocypodioidea ） 、溪蟹總科（ potamoidea ）和梭子蟹總科（ portunoidea ）的蟹類起源於一個共同的海洋蟹類祖先，它們彼此之間的歧異時間基本一致。
