FIG. 1. Distribution and relationships of the B. pacificus group. (A) Colored polygons show the ranges of the seven species currently recognized in B. pacificus (based on IUCN range polygons), and black dots show the locations of molecular samples included in this study; brown polygon shows range of B. nigriventris. Arrow and purple circle indicate the locality of the species described here. Map tiles by Stamen Design, under a CC BY 3.0 license. Map data by OpenStreetMap under ODbL. (B) Species tree for the B. pacificus group and selected outgroups inferred from coalescent analysis of seven nuclear and one mitochondrial marker. Support values are ASTRAL-III's local posterior probabilities; branch lengths are in coalescent units. See Data Accessibility for tree file.
