FIGURE 1. Tree obtained from the concatenated analysis of H3, 16S and COI through Maximum Likelihood and Inference Bayesian. Each color represents the subfamilies recognized by Álvarez et al. (2020): red—Ptychophallinae; green— Potamocarcininae; yellow—Raddausinae and purple—Pseudothelphusinae.The lineages of Ehecatusa and Xoconochcothelphusa genera were colored with blue.
