Stenophis is a genus of Madagascan arboreal snakes, part of the family Lamprophiidae. Species of Stenophis typically have large heads relative to their body size, and their bodies are elongated and often thin.[1] The genus includes both viviparous and oviparous species.[2] They usually have prolate pupils.
Taxonomy
Stenophis was previously considered to be part of the genus Lycodryas until the mid-1990s.[1]
A phylogenetic analysis in 2008 found that the genus is polyphyletic,[3] and a 2010 study proposed three monophyletic genera of the snakes currently in Stenophis and Lycodryas: Lycodryas (with Stenophis as a junior synonym), Phisalixella, and Parastenophis.[4]
Species
Known species of Stenophis include:[1]
- Stenophis arctifasciatus (A.M.C. Duméril, Bibron & A.H.A. Duméril, 1854)
= Phisalixella arctifasciata (A.M.C. Duméril, Bibron & A.H.A. Duméril, 1854) - Stenophis betsileanus (Günther, 1880) = Parastenophis betsileanus (Günther, 1880)
- Stenophis carleti Domergue, 1995 = Lycodryas carleti (Domergue, 1995)
- Stenophis citrinus Domergue, 1995 = Lycodryas citrinus (Domergue, 1995)

Nota bene: A binomial authority in parentheses indicates that the species was originally described in a different genus.
