“…Our results support previous findings of monophyly for the subfamily Natricinae (Lawson et al, 2005;Pyron et al, 2011). We demonstrate that a basal split separates two diverse clades, the first composed mostly of Asian genera and the three African genera: Afronatrix, Amphiesma, Atretium, Lycognathophis, Macropisthodon, Natriciteres, Rhabdophis, Trachischium and Xenochrophis.…”

“…1). Similar to Pyron et al (2011) and Alfaro and Arnold (2001), several NW thamnophiine genera are demonstrated to be paraphyletic, including Thamnophis, Nerodia and Regina. If these results are supported by sampling of additional species, loci, and coalescent-based species tree analyses, then major taxonomic rearrangements would be necessary to correct paraphyletic genera in both clades.…”

“…Two Asian genera, Sinonatrix and Opisthotropis, are each strongly supported as monophyletic, and together form the sister group to the clade composed of Natrix and Thamnophiini. Similar to Pyron et al (2011), several thamnophine genera are paraphyletic, including Thamnophis, Nerodia, and Regina.…”

“…We sequenced c-mos, ND2, ND4 and cyt b for 18 additional individuals (15 species, 7 genera). To investigate the monophyly of Natricinae and to clarify the systematic position of Trachischium monticola, a poorly known putative colubrid, two representatives from the other subfamilies of Colubridae (Immantodes cenchoa and Coluber constrictor) as well as one homalopsid (Enhydris plumbea), were chosen as outgroups based on previous studies (Lawson et al, 2005;Pyron et al, 2011).…”

“…These include studies that addressed the impact of including incomplete taxa, the impact of incomplete characters, and the impacts of missing data on branch-length estimation and support values (e.g. Wiens, 2003Wiens, , 2005Driskell et al, 2004;Philippe et al, 2004;Wiens and Moen, 2008;Burleigh et al, 2009;Lemmon et al, 2009;Sanderson et al, 2010Sanderson et al, , 2011Cho et al, 2011;Pyron et al, 2011;Wiens and Morrill, 2011;Crawley and Hilu, 2012;Simmons, 2012Simmons, , 2014Wiens and Tiu, 2012;Hovmöller et al, 2013;Roure et al, 2013;Jiang et al, 2014). However, an important and largely unresolved question is how missing data impact divergence-time estimation.…”

Snakes are a diverse group of long‐bodied, limb‐reduced reptiles closely related to lizards; together they are termed squamate reptiles. Primitive snakes with vestigial legs appear in the fossil record of the Cretaceous period (∼90 Mya). Snakes have since been diversified rapidly, and now comprise ∼3500 species that occupy terrestrial, subterranean, aboreal and aquatic niches. All snakes are predators, having highly mobile skulls and jaws that can often swallow prey much larger than their own diameter. Primitive snakes such as boas, pythons and blindsnakes lack venom fangs. Such fangs have evolved repeatedly within more advanced snakes, called the Colubroidea, which make up ∼80% of the diversity of living snakes: front fangs in viperids (e.g. vipers and rattlesnakes), fixed front fangs in elapids (e.g. mambas and cobras) and rear fangs in many lineages of colubrids (e.g. boomslangs and twig snakes). Key Concepts: Snakes are just one of the many lineages of limb‐reduced lizards – though by far the most successful ones. Snakes have highly flexible (kinetic) skulls and lower jaws, and many forms can engulf prey wider than their heads. Snakes are one of the most rapidly diversifying groups, with more than 3000 living species, mostly belonging to the Colubroidea. Venom‐delivery systems (fangs and glands) have evolved multiple times within the most advanced snake lineage (Colubroidea). The fossil snakes Najash and Pachyrhachis (∼90 My old) retain prominent external hindlimbs, as would be expected given that snakes evolved from lizard‐like reptiles.
