Maximum likelihood phylogeny of the Pedioplanis undata species complex inferred from the concatenation of the two mitochondrial genes ND2 and cyt b. Major geographically-structured clades are depicted for each species: (a.) P. branchi sp. nov. (yellow), P. gaerdesi (green), P. mayeri sp. nov. (teal), P. rubens (brown), (b.) P. inornata (blue) and P. undata (orange). Triangles indicate multiple sampled specimens. Locality names in bold refer to more inclusive area represented by the clade, parenthetical place names are main specific localities. Number ranges correspond to the sample numbers in Suppl. material 1: complete list of of tissue specimen and GenBank sampling. Node support labels are represented by bootstrap values (BS), with black nodes denoting BS ≥ 90, gray nodes denoting 90 > BS ≥ 70, and white nodes denoting BS < 70; bootstrap values of 100 are not shown.
