Bayesian inference (BI) tree based on the COI sequences of 14 Scomberomorus species. The green clades represent five species for which the species delimitation result is different based on morphology and the BI tree: S. commerson, S. guttatus, S. plurilineatus, S. regalis, and S. maculatus. Images of the genus Scomberomorus on the right from top to bottom are: S. sierra, S. concolor, S. brasiliensis, S. regalis, S. maculatus, S. semifasciatus, S. cavalla, S. niphonius, S. munroi, S. guttatus, S. plurilineatus, S. commerson, and S. queenslandicus. MT680627 is the outgroup. Numbers near the branches are bootstrap values.
