FIGURE 2. Phylogenetic relationships of Hydropsini (one species of Hydrops, one species of Pseudoeryx, and 11 species of Helicops) based on a concatenated matrix of the 12S, 16S, BDNF, C-mos, and NT3 sequence data. Numbers at nodes indicate the values of Bayesian Credibility/Maximum Likelihood bootstrap. The bar represents the number of expected changes per site in the Bayesian Analysis. Terminal H1733 corresponds to the voucher MZUSP 19695. The name Helicops pictiventris is currently in the synonymy of He. infrataeniatus, but appears in the tree exactly as the pertinent sequences appear in the GenBank (see Zaher et al. 2009).
Data from: The cat-eyed snakes of Madagascar: phylogeny and description of a new species of Madagascarophis (Serpentes: Lamprophiidae) from the tsingy of Ankarana
The cat-eyed snakes of the genus Madagascarophis are among the most commonly encountered snake species in Madagascar. Yet despite their broad distribution and frequent occurrence in human-disturbed habitat, Madagascarophis still contains unrecognized species diversity. Here, we describe a new species of Malagasy cat-eyed snake from a specimen found in the tsingy karst system of Ankarana in northern Madagascar. Using multiple loci from all currently described species, including the never-before-sequenced M. ocellatus, we delimit a new species and also determine its placement within the genus in a Bayesian coalescent framework, using BPP and *BEAST, respectively. Our results indicate that molecular data are sufficient to delimit this new taxon. These data also support its placement as the sister taxon to the recently described M. fuchsi which is endemic to the Montagne des Français karst massif also in northern Madagascar. We also provide a morphological description of this new snake species, which can be readily diagnosed based on external morphological characters, and include a species identification key for the entire genus based on external morphology.
