Stenophis
''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.〔 The genus includes both viviparous and oviparous species. They usually have prolate pupils. ==Taxonomy== ''Stenophis'' was previously considered to be part of the genus ''Lycodryas'' until the mid-1990s.〔 A phylogenetic analysis in 2008 found that the genus is polyphyletic, 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''.
