Tropidodipsas tricolor & T. papavericola • Two New Species of Snail-eating Snakes of the Genus Tropidodipsas (Serpentes, Dipsadidae) from southern Mexico, with Notes on Related Species

We describe two new species of Tropidodipsas related to the T. fasciata species group as defined by Kofron (1987), and provide morphological and molecular data to support the novelty of both species. A partial molecular phylogeny of the Mexican species of snail-eating snakes (Serpentes, Dipsadidae) is presented, and we discuss evolutionary relationships as supported by our molecular results.  Leer más.
