Highest likelihood trees resulting from maximum-likelihood analysis of COI alignment. Ultra-fast bootstrap values >95% are shown with black branches, 50–94% with gray branches and <50 with dashed gray branches. Terminals are labeled with Genbank voucher numbers, species, and sampling locality for our focal taxa. Type localities are indicated with an *. The new species and select relatives are figured.
