Atractus is a genus of colubrid ground snakes in the subfamily Dipsadinae. The genus includes more than 140 distinct species. [2]
Snakes of the genus Atractus are endemic to Central and South America. [1]
In the genus Atractus the maxilla is short, with 8–12 teeth; the maxillary and mandibular teeth decrease in size posteriorly. The head is not distinct from the neck. The eye is small, with a round or subelliptic pupil. The nostril is between two nasal scales. The preocular is usually absent, and the loreal and prefrontal scales enter the orbit. The body is cylindrical. The dorsal scales are smooth, without apical pits, in 15 or 17 rows. The ventral scales are rounded. The tail can be either short or rather long. The subcaudals are paired.

The following species are recognized as being valid. [3]
Nota bene : A binomial authority in parentheses indicates that the species was originally described in a genus other than Atractus.
Gonatodes is a genus of New World dwarf geckos of the family Sphaerodactylidae.
Phyllodactylus is a genus of geckos distributed in South America and Central America, and as far north as the southern United States. They are commonly known as "leaf-toed geckos" in their native range, and otherwise as American leaf-toed geckos to distinguish them from unrelated genera with similar feet.
Coral snakes are a large group of elapid snakes that can be divided into two distinct groups, the Old World coral snakes and New World coral snakes. There are 16 species of Old World coral snakes, in three genera, and over 65 recognized species of New World coral snakes, in two genera. Genetic studies have found that the most basal lineages have origins in Asia, suggesting that the group originated in the Old World. While new world species of both genera are venomous, their bites are seldom lethal; only two confirmed fatalities have been documented in the past 100 years from the genus Micrurus. Meanwhile, snakes of the genus Micruroides have never caused a medically significant bite.
Chironius is a genus of New World colubrid snakes, commonly called sipos, savanes, or sometimes vine snakes. There are 23 described species in this genus.
Erythrolamprus is a genus of colubrid snakes, commonly known as false coral snakes, native to Central America, the Caribbean, and the northern part of South America. They appear to be coral snake mimics.
Bothrops insularis, commonly known as the golden lancehead, is a highly venomous pit viper species found exclusively on the Ilha da Queimada Grande, off the coast of São Paulo state, in Brazil. The species is named for the light yellowish-brown color of its underside and for its head shape that is characteristic of the genus Bothrops. No subspecies of Bothrops insularis are currently recognized. It is one of the most venomous snakes in Latin America.
Dipsas is a genus of nonvenomous New World snakes in the subfamily Dipsadinae of the family Colubridae. The genus Sibynomorphus has been moved here. Species of the genus Dipsas are known as snail-eaters.
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.
Synophis is a genus of snakes in the family Colubridae. The genus is endemic to northwestern South America.
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.
Synophis insulomontanus, known commonly as the mountain shadow snake, is a species of snake in the family Colubridae. The species is endemic to northwestern South America.
Trilepida is a genus of snakes in the family Leptotyphlopidae.
Atractus alphonsehogei, also known commonly as Alphonse's ground snake, is a species of snake in the family Colubridae. The species is endemic to Brazil.
Atractus emigdioi, also known commonly as Emigdio's ground snake, is a species of snake in the family Colubridae. The species is endemic to Venezuela.
Atractus gaigeae, also known commonly as Gaige's ground snake, is a species of snake in the family Colubridae. The species is endemic to Ecuador.
Atractus guentheri, also known commonly as Günther's ground snake and coral-falsa in Brazilian Portuguese, is a species of snake in the subfamily Dipsadinae of the family Colubridae. The species is endemic to Brazil.
