Sibon canopy, S. vieirai, Dipsas welborni, etc. • A Consolidated Phylogeny of Snail-eating Snakes (Serpentes, Dipsadini), with the Description of Five New Species from Colombia, Ecuador, and Panama

A molecular phylogeny of the Neotropical snail-eating snakes (tribe Dipsadini Bonaparte, 1838) is presented that includes 60 of the 133 species currently recognized. There is morphological and phylogenetic support for four new species of Sibon Fitzinger, 1826 and one of Dipsas Laurenti, 1768, which are described here based on their unique combination of molecular, meristic, and color pattern characteristics.  Leer más.
