“…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.…”

“…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).…”

“…The entire gene sequences for the mitochondrial cytochrome b (cyt b) and NADH dehydrogenase subunit 2 (ND2), the partial gene sequences of NADH dehydrogenase subunit 4 (ND4) and one nuclear gene c-mos were amplified by the polymerase chain reaction (PCR) using primers L14910/H16064 (Burbrink et al, 2000), L5238/H5382 (de Queiroz et al, 2002), ND4/Leu (Arèvalo et al, 1994) and S77/S78 (Lawson et al, 2005), respectively. The cycling parameters were identical to those described in above studies.…”

A large body of evidence indicates that evolutionary innovations of novel organs have facilitated the subsequent diversification of species. Investigation of the evolutionary history of such organs should provide important clues for understanding the basis for species diversification. An Asian natricine snake, Rhabdophis tigrinus, possesses a series of unusual organs, called nuchal glands, which contain cardiotonic steroid toxins known as bufadienolides. Rhabdophis tigrinus sequesters bufadienolides from its toad prey and stores them in the nuchal glands as a defensive mechanism. Among more than 3,500 species of snakes, only 17 Asian natricine species are known to possess nuchal glands or their homologues. These 17 species belong to three nominal genera, Balanophis, Macropisthodon, and Rhabdophis. In Macropisthodon and Rhabdophis, however, species without nuchal glands also exist. To infer the evolutionary history of the nuchal glands, we investigated the molecular phylogenetic relationships among Asian natricine species with and without nuchal glands, based on variations in partial sequences of Mt‐CYB, Cmos, and RAG1 (total 2,767 bp). Results show that all species with nuchal glands belong to a single clade (NGC). Therefore, we infer that the common ancestor of this clade possessed nuchal glands with no independent origins of the glands within the members. Our results also imply that some species have secondarily lost the glands. Given the estimated divergence time of related species, the ancestor of the nuchal gland clade emerged 19.18 mya. Our study shows that nuchal glands are fruitful subjects for exploring the evolution of novel organs. In addition, our analysis indicates that reevaluation of the taxonomic status of the genera Balanophis and Macropisthodon is required. We propose to assign all species belonging to the NGC to the genus Rhabdophis, pending further study.

Reduced representation genome sequencing has ushered in new methods for understanding how life evolved on earth. These methods utilise genetic data in the form of dozens, hundreds or even thousands of loci to estimate phylogenetic relationships. This approach, often termed phylogenomic analysis, has the potential to resolve controversial evolutionary relationships, particularly among ancient, rapid radiations. Among vertebrates, phylogenomic analyses are increasingly applied to an iconic group of reptiles, snakes. Phylogenomic analyses of snakes have begun to shed light on long‐standing questions including relationships among snake families, their origin among squamate reptiles and putative causes of speciation within recent radiations. In addition, these methods may even be used to obtain genetic data from archival museum specimens. This emerging approach for understanding snake evolution will be improved by whole genome sequencing initiatives that include a diverse group of snake species. Key Concepts Snakes are important study systems for human physiology and medicine. Snakes are important predators in ecosystems/important to maintaining ecosystem health. Robust phylogenetic hypotheses are necessary to understand snake evolution. Genome‐wide data offer unprecedented opportunities to resolve snake phylogeny and the tree of life. Phylogenomic analyses of snakes will aid biologists and medical researchers worldwide.
