Polemon is a genus of rear-fanged mildly venomous snakes in the family Atractaspididae. The genus is endemic to Africa. Fifteen species are recognized as being valid.
Tachymenis is a genus of venomous snakes belonging to the family Colubridae. Species in the genus Tachymenis are commonly known as slender snakes or short-tailed snakes and are primarily found in southern South America. Tachymenis are rear-fanged (opisthoglyphous) and are capable of producing a medically significant bite, with at least one species, T. peruviana, responsible for human fatalities.
Oxyrhopus, the false coral snakes, is a genus of colubrid snakes that belong to the subfamily Dipsadinae. The genus is found in Central America and the northern part of South America, and it includes 15 distinct species.
Oxyrhopus melanogenys, commonly known as Tschudi's false coral snake, is a colubrid snake species found in the northern part of South America.
Chironius laurenti is a species of nonvenomous snake in the family Colubridae. The species is endemic to Bolivia and Brazil. The species was named in honor of Raymond Laurent.
Colubroidea is a superfamily of snakes in the clade Colubroides that includes Colubridae, with some studies splitting Colubridae into multiple families that make up Colubroidea. Historically, Colubroidea also included other caenophidian snakes such as cobras and vipers, as these snakes form a clade. However these groups are now divided into several distinct, but related, families. Zaher et al. (2009) proposed to redefine Colubroidea for colubrids and related families, while designating Colubroides as the group containing vipers and cobras as well as colubroids. The ReptileDatabase considers Colubroidea to be composed of Colubridae and the members of its sister group, Elapoidea, and does not recognize the division of Colubridae into multiple families.
Dipsadinae is a large subfamily of colubroid snakes, sometimes referred to as a family (Dipsadidae). They are found in most of the Americas, including the West Indies, and are most diverse in South America. There are more than 700 species.
Pseudoxenodontinae is a small subfamily of colubroid snakes, sometimes referred to as a family (Pseudoxenodontidae). They are found in southern and southeastern Asia, from northeast India to southern China and south into Indonesia as far east as Wallace's Line. There are 10 species in 2 genera. Most are very poorly known, such that Pseudoxenodontinae is one of the most poorly known groups of snakes.
Wallaceophis is a genus of snake in the family Colubriadae. It was first described in 2016. The sole species is Wallaceophis gujaratensis which is found in the Indian state of Gujarat. Wallaceophis gujaratenisis is presently known from just seven localities of Gujarat and virtually nothing is known about its biology. Common names Wallace's striped snake and Wallace's racer has been suggested for it.
Synophis bicolor, known commonly as the bicolored shadow snake or the two-colored fishing snake, is a species of snake in the family Colubridae. The species is endemic to northwestern South America.
Dryophylax almae is a species of snake in the family Colubridae. The species is endemic to Brazil.
The Colubroides are a clade in the suborder Serpentes (snakes). It contains over 85% of all the extant species of snakes. The largest family is Colubridae, but it also includes at least six other families, at least four of which were once classified as "Colubridae" before molecular phylogenetics helped in understanding their relationships. It has been found to be monophyletic.
Lycophidion depressirostre, commonly known as the flat-snouted wolf snake, is a rare species of oviparous, nonvenomous snake in the family Lamprophiidae. It is found in southern Sudan, the Central African Republic, Somalia, Kenya, Tanzania, Uganda, and Southern Ethiopia.
