Fig. 1. Bayesian and Maximum Likelihood concatenated tree (based on 16S and COI) of selected species of Salmoneus with focus on the S. cristatus species group, showing two different clades morphologically allied to S. cristatus. Numbers above or under each branch are bootstrap supports and Bayesian posterior probabilities, respectively (supports and probabilities under 60/0.6 are not shown). Insert photographs show S. franseni sp. nov. (yellow clade) and S. cristatus (red clade).
