Fig. 19. Parsimony-based morphological character optimization over molecular phylogenetic tree of sampled species of Tropidophiidae Brongersma, 1951, as inferred with YBYRÁ software, and occurrence of species in South America and the West Indies. Left: Nodes are labeled with unambiguously optimized morphological synapomorphic characters (black square = unique, non-homoplastic; red square = nonunique, homoplastic; blue square = unique, homoplastic; character number = value below or above squares; derived character-states = value inside squares). Right: Geographic distribution of sampled terminals of Tropidophiidae.
