Phylogenetic maximum likelihood (ML) tree of Somanniathelphusa boyangensis and related brachyurans based on 11 PCGs sequences from the mitochondrial genome; Panulirus ornatus serves as the outgroup.
The numbers at the internodes are maximum likelihood (ML) bootstrap proportions and Bayesian inference (BI) posterior proportions. The differences between the ML and BI trees are indicated by ‘*’. The scale bars represent genetic distance.
