Data matrix of 20 Tropidurus species used in the Brooks Parsimony Analysis (BPA) employing the biogeographic provinces of South America as operational geographic units [57]–[58].

Absence of taxon codified as “0”, presence codified as “1”. Taxa: (1) T. bogerti, (2) T. callathelys, (3) T. chromatops, (4) T. cocorobensis, (5) T. erythrocephalus, (6) T. etheridgei, (7) T. guarani, (8) T. hispidus, (9) T. hygomi, (10) T. insulanus, (11) T. itambere, (12) T. melanopleurus, (13) T. montanus, (14) T. mucujensis, (15) T. oreadicus, (16) T. psammonastes, (17) T. semitaeniatus, (18) T. spinulosus, (19) T. torquatus, (20) T. xanthochilus. Note: T. helenae, T. jaguaribanus, and T. pinima (from Caatinga province) were not included since these species were absent from the phylogenetic hypothesis of Frost et al.[9], used for implementation of BPA. Hypothetical ancestors are represented in Fig. 1.
