Leptophis is a genus of colubrid snakes, commonly known as parrot snakes. The species within this genus are widely distributed throughout Mexico, Central and South America. [1]
The genus Leptophis belongs to the subfamily Colubrinae, of the family Colubridae. The species relationships within Leptophis can be shown in the cladogram below, with possible paraphyletic species identified: [2]

Snakes of the genus Leptophis are slender with a long tail. The body is cylindrical or slightly laterally compressed. The head is elongated and distinct from the neck. The eye is large with a round pupil. The dorsal scales are arranged in 15 rows at midbody. The maxillary teeth, which number 20–32, are in a continuous series without any interspace, and are longest posteriorly. Conversely, the mandibular teeth are longest anteriorly. [3]
The following species and subspecies are currently recognized as being valid:

Micrurus is a genus of venomous coral snakes of the family Elapidae.
Leptophis ahaetulla, commonly known as the lora or parrot snake, is a species of medium-sized slender snake of the family Colubridae. The species is native to Central America and northern South America.
Ahaetulla, commonly referred to as Asian vine snakes or Asian whip snakes, is a genus of colubrid snakes distributed throughout tropical Asia. They are considered by some scientists to be mildly venomous and are what is commonly termed as 'rear-fanged' or more appropriately, opisthoglyphous, meaning their enlarged teeth or fangs, intended to aid in venom delivery, are located in the back of the upper jaw, instead of in the front as they are in vipers or cobras. As colubrids, Ahaetulla do not possess a true venom gland or a sophisticated venom delivery system. The Duvernoy's gland of this genus, homologous to the venom gland of true venomous snakes, produces a secretion which, though not well studied, is considered not to be medically significant to humans.
Tantilla is a large genus of harmless New World snakes in the family Colubridae. The genus includes 66 species, which are commonly known as centipede snakes, black-headed snakes, and flathead snakes.
The Natricinae are a subfamily of colubroid snakes, sometimes referred to as a family (Natricidae). The subfamily comprises 36 genera. Members include many very common snake species, such as the European grass snakes, and the North American water snakes and garter snakes. Some Old World members of the subfamily are known as keelbacks, because their dorsal scales exhibit strong keeling.
The Colubrinae are a subfamily of the family Colubridae of snakes. It includes numerous genera, and although taxonomic sources often disagree on the exact number, The Reptile Database lists 717 species in 92 genera as of September 2019. It is the second largest subfamily of colubrids, after Dipsadinae. Many of the most commonly known snakes are members of this subfamily, including rat snakes, king snakes, milk snakes, vine snakes, and indigo snakes.
Lycodon is a genus of colubrid snakes, commonly known as wolf snakes. The Neo-Latin name Lycodon is derived from the Greek words λύκος (lykos) meaning wolf and οδόν (odon) meaning tooth, and refers to the fang-like anterior maxillary and mandibular teeth. They are nonvenomous, but many members of this genus strongly resemble the venomous kraits in appearance, an example of Emsleyan mimicry.
Leptophis mexicanus, commonly known as the Mexican parrot snake, is a species of medium-sized slender snake in the family Colubridae. The species is endemic to the Americas.
Leptophis nigromarginatus, commonly known as the black-skinned parrot snake, is a snake of the family Colubridae.
Leptophis modestus, commonly known as the cloud forest parrot snake, is a species of medium-sized slender snake of the family Colubridae. It is endemic to Mesoamerica. There are currently no recognized subspecies.
Leptophis diplotropis, commonly known as the Pacific Coast parrot snake, is a species of snake in the family Colubridae. The species is endemic to Mexico.
Dipsadinae is a large subfamily of colubroid snakes, sometimes referred to as a family (Dipsadidae). Species of the subfamily Dipsadinae are found in most of the Americas, including the West Indies, and are most diverse in South America. There are more than 700 member species.
Boaedon olivaceus is a species of snake in the family Lamprophiidae. The species is endemic to Africa.
Leptophis coeruleodorsus, the green-and-yellow parrot snake or Oliver's parrot snake, is a species of nonvenomous snake in the family Colubridae. It is found in Venezuela and Trinidad and Tobago.
