Stenophis
Stenophis is a genus of Madagascan arboreal snakes, part of the Lamprophiinae. They typically have large heads relative to their body size, and they 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]
