Helicops is a genus of snakes of the family Colubridae. The genus is endemic to South America.
The following 20 species are recognized as being valid. [1]
Nota bene : A binomial authority in parentheses indicates that the species was originally described in a genus other than Helicops.
Bachia is a genus of lizards that belong to the spectacled lizards family.
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.
Micrurus is a genus of venomous coral snakes of the family Elapidae.
Philodryas is a genus of colubrid snakes endemic to South America, commonly called green 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.
Rhabdophis is a genus of snakes in the subfamily Natricinae of the family Colubridae. Species in the genus Rhabdophis are generally called keelback snakes, and are found primarily in Southeast Asia.
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.
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.

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.
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.
Atractus is a genus of colubrid ground snakes in the subfamily Dipsadinae. The genus includes more than 140 distinct species.
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.
Apostolepis is a genus of snakes in the subfamily Dipsadinae. However, the familial placement differs among sources. It has also been placed in the family Colubridae, subfamily Dipsadinae or Xenodontinae, or in the family Xenodontidae. The genus Apostolepis is endemic to South America.
Tropidonophis is a genus of snakes in the subfamily Natricinae of the family Colubridae.
Trilepida is a genus of snakes in the family Leptotyphlopidae.
