Fig. 1 in Unearthing the species diversity of a cryptozoic snake, Tantilla melanocephala, in its northern distribution with emphasis on the colonization of the Lesser Antilles
Fig. 1. (A) Tantilla melanocephala sample localities for this study (red circles) in the northern region of its distribution. (B) The distribution of Tantilla melanocephala in the Neotropics. Locality data are from VertNet and the GBIF databases, as well as the literature (Nogueira et al. 2019). Within the Lesser Antilles, Union Island and the Mustique islands are not shown. Red circles are T. melanocephala localities included in the phylogenetic analyses. The map suggests this species inhabits several different biomes.

Fig. 4. Bayesian time tree as inferred by BEAST for the data set of concatenated 12S and 16S rDNA, cytb, and c-mos sequences from Tantilla specimens (in red). Red values by nodes denote the median time estimates, whereas values in brackets denote 95% Highest Posterior Density ranges. Red and black nodes are posterior probabilities (1.00 and> 95–99%), respectively. Photo by J.C. Murphy.

Fig. 3. Best Maximum Likelihood tree based on the data set of concatenated 12S and 16S rDNA, cytb, and c-mos sequences. Red clade depicts the genus Tantilla. Values on the left and right sides of a slash (/), are the values indicated at nodes of Maximum Likelihood bootstraps (>70%) and Bayesian Posterior probability values (>95%), respectively. The Tantilla melanocephala pictured is from the western versant of the Occidental slopes in Ecuador (from the Rio Manduriacu Reserve). Photo by R. Maynard.
