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.
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]
Known species of Stenophis include: [1]
Nota bene : A binomial authority in parentheses indicates that the species was originally described in a different genus.
Paroedura is a genus of geckos, endemic to Madagascar and the Comoros. These geckos are typically terrestrial, though the young of most species can climb until they are too heavy for their feet to support.
Madagascarophis is a genus of small, mildly venomous snakes native to the island of Madagascar. They are commonly referred to as Malagasy cat-eyed snakes. Five species are in the genus.
Dromophis is a genus of colubrid snakes. There are two commonly accepted species in the genus Dromophis:
Eirenis is a genus of Old World snakes in the family Colubridae.
The Pseudoxyrhophiidae is a family of elapoid snakes, found mostly in Madagascar. They were formerly placed as a subfamily of the Lamprophiidae, but have been more recently identified as a distinct family.
Scincinae is a subfamily of lizards. The subfamily contains 33 genera, and the genera contain a combined total of 284 species, commonly called skinks. The systematics is at times controversial. The group is probably paraphyletic. It is one of three subfamilies of the family Scincidae, the other two being Acontinae and Lygosominae.
Dipsas is a genus of nonvenomous New World snakes in the subfamily Dipsadinae of the family Colubridae. The genus Sibynomorphus has been moved here. The genus Dipsas are known as snail-eater.
Ithycyphus miniatus is a species of venomous snake in the family Pseudoxyrhophiidae. The species is native to Madagascar.
Thamnosophis is a genus of pseudoxyrhophiid snakes found only on the island of Madagascar. As of 2014, six species were recognized.
Liophidium is a genus of snakes in the family Pseudoxyrhophiidae. The genus contains ten species, nine of which are endemic to the island of Madagascar and one to the island of Mayotte. All species of Liophidium are harmless to humans.
Lycodryas is a genus of snakes in the family Pseudoxyrhophiidae. The genus contains nine species, seven of which are endemic to the island of Madagascar, and two to the Comoros Islands. All of the species are harmless to humans.
Phisalixella is a genus of pseudoxyrhophiid snakes endemic to the island of Madagascar. They are harmless to humans.
Xenodon is a genus of New World snakes in the subfamily Dipsadinae of the family Colubridae.
Compsophis is a genus of harmless snakes in the family Pseudoxyrhophiidae. The genus is found only on the island of Madagascar.
Uromacer is a genus of snakes in the family Colubridae endemic to the island of Hispaniola.
Oligodon huahin is a species of kukri snakes in the genus Oligodon. The species was first discovered and described in late 2016, and the article was published July 13, 2017. It is only known from its type locality but its range is likely to be more extensive. O. huahin is thought to be very secretive, similar to other species of the genus Oligodon. This theory is supported by the type specimen, which all were males, suggesting that it was found during the mating season where males are out and actively search for females to reproduce. This may also explain why this species had not yet been discovered
Thamnosophis stumpffi, commonly known as the yellow-striped water snake, is a species of snake in the subfamily Pseudoxyrhophiinae of the family Pseudoxyrhophiidae. The species is endemic to Madagascar.
