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.

All homologous partial sequences of COI and 16S in Portunidae were collected from GenBank and aligned with the homologous sequences of P.trituberculatus. The NJ tree and MP tree were constructed using Kimura 2-parameter model. Homologous sequences (429 bp) of sampled specimen and genus Charybdis were aligned.
结合GenBank中收集的梭子蟹科COI，16 S rRNA两个基因所有同源序列信息，使用Kimura双参数模型采用邻接法、最大简约法构建梭子蟹科分子系统发育树；将样品蟹测得的COI基因序列和已知属的其他蟹同源序列(429 bp)进行比对分析。
