“…Surprisingly, the tribe Dipsadini, as defined by Zaher (1999) and Harvey et al (2008) (i.e. including the genera Dipsas, Sibynomorphus, Sibon, Tropidodipsas and Plesiodipsas), is paraphyletic in respect to Ninia in the MP trees.…”

We present a phylogenetic analysis of the New World dipsadids based on an expanded data matrix that includes 246 terminal taxa including 196 dipsadids. The species are sampled for eight genes (12S, 16S, cytb, nd2, nd4, bdnf, c‐mos, rag2). The data are explored using two distinct optimality procedures—maximum parsimony and maximum likelihood—and two alignment strategies—dynamic homology and static homology. Two previously unsampled dipsadid genera, Sordellina and Rhachidelus, are now included in the analysis. The definitions of the genera, Erythrolamprus, Clelia, Hypsirhynchus, Philodryas and Phimophis, and the tribes Alsophiini, Echinantherini and Conophiini, are revised. In order to maintain monophyly, the genus Umbrivaga is synonymized with Erythrolamprus, and two new genera are erected to accommodate Phimophis iglesiasi and Clelia rustica, as well as their closely related species. The West Indian genera Schwartzophis, Darlingtonia, Antillophis and Ocyophis are resurrected. © The Willi Hennig Society 2012.

“…Some authors have suggested that their tree-dwelling lifestyle and specialized diet resulted this large an adaptive radiation (e.g., MacCulloch and Lathrop 2004 ; Sheehy 2012 ). In the last decade, the limits of the tribe have been redefined to include five genera ( Dipsas , Plesiodipsas , Sibon , Sibynomorphus , and Tropidodipsas ; Harvey et al 2008 ), but recent studies suggest that not all of them are monophyletic ( Sheehy 2012 ; Figueroa et al 2016 ). Consequently, the limits between genera, species, and species groups appear to be poorly defined, and in need of revision for a robust and stable taxonomy.…”

“…Peters considered Dipsadini to include the genera Dipsas , Sibon and Sibynomorphus . Later, Zaher (1999) and Harvey et al (2008) added Tropidodipsas and Plesiodipsas in the tribe. Peters also created seven species groups within Dipsas , three within Sibon (Table 1 ), and recognized D. boettgeri , D. latifrontalis , D. latifasciata , D. polylepis , and D. peruana as distinct species based on coloration and lepidosis.…”

A molecular phylogeny of the Neotropical snail-eating snakes (tribe Dipsadini) is presented including 43 (24 for the first time) of the 77 species, sampled for both nuclear and mitochondrial genes. Morphological and phylogenetic support was found for four new species of Dipsas and one of Sibon, which are described here based on their unique combination of molecular, meristic, and color pattern characteristics. Sibynomorphus is designated as a junior subjective synonym of Dipsas. Dipsas latifrontalis and D. palmeri are resurrected from the synonymy of D. peruana. Dipsas latifasciata is transferred from the synonymy of D. peruana to the synonymy of D. palmeri. A new name, D. jamespetersi, is erected for the taxon currently known as Sibynomorphus petersi. Re-descriptions of D. latifrontalis and D. peruana are presented, as well as the first photographic voucher of an adult specimen of D. latifrontalis, along with photographs of all known Ecuadorian Dipsadini species. The first country record of D. variegata in Ecuador is provided and D. oligozonata removed from the list of Peruvian herpetofauna. With these changes, the number of Dipsadini reported in Ecuador increases to 22, 18 species of Dipsas and four of Sibon.

“…Molluscivory has evolved at least five separate times and is characterized by a suite of similar morphological adaptations of the skull, teeth, and cephalic musculature (Dunn, 1951;Peters, 1960;Savitzky, 1983;Gruz, 2002;Hoso et al, 2007). Snakes of the genus Dipsas and, to a lesser degree, Sibon, are morphologically specialized to facilitate the extraction and handling of mollusks (Dunn, 1951;Peters, 1960;Savitzky, 1983;Sousa do Amaral, 1999;Cundall and Greene, 2000;Gruz, 2002;Savage, 2002;Harvey et al, 2008). The radiation of molluscan specialists is greatest in the Neotropical region (Central and South America) and includes five genera in the tribe Dipsadinae: Dipsas, Plesiodipsas, Sibon, Sibynomorphus, and Tropidodipsas (Peters, 1960;Cadle, 2007).…”
