Lystrophis is the genus of tricolored South American hognose snakes. They mimic milk snakes or coral snakes with their red, black, and white ringed patterns.
The genus Lystrophis contains five species that are recognized as being valid. [1]
Lystrophis dorbignyi is the type species for the genus Lystrophis. [2]
Nota bene : A binomial authority in parentheses indicates that the species was originally described in a genus other than Lystrophis.
All species of Lystrophis are sometimes included in the genus Xenodon .
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 27 species of Old World coral snakes, in three genera, and 83 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.
Boiga is a large genus of rear-fanged, mildly venomous snakes, known commonly as cat-eyed snakes or simply cat snakes, in the family Colubridae. Species of the genus Boiga are native to southeast Asia, India, and Australia, but due to their extremely hardy nature and adaptability, have spread to many other suitable habitats around the world. There are 38 recognized species in the genus. According to the study done by Jiří Smíd regarding Old World cat snakes, the ancestor of the cat snake originated in Africa, from where it diversified and expanded to other countries. Despite this diversity however, the different species have very similar needs in terms of temperature and precipitation.

Oxyrhopus, the false coral snakes, is a genus of colubrid snakes that belong to the subfamily Dipsadinae. All 15 members of the genus are found in the northern part of South America, with the native range of the most widespread member, Oxyrhopus petolarius, extending into Central America and Trinidad and Tobago as well.
Mastigodryas is a genus of colubrid snakes. Like some other colubrids, they are commonly called racers. It is a Neotropical genus, with members distributed from Mexico to Argentina and several islands in the Caribbean. Some authorities use the older generic name, Dryadophis, for these species.
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.
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.
Xenodon is a genus of New World snakes in the subfamily Dipsadinae of the family Colubridae.

Pseudoboa, the false boas, is a genus of snakes in the family Colubridae. The genus is endemic to South America.
Stegonotus is a genus of snakes in the family Colubridae. Species of the genus Stegonotus are native to Australia, Indonesia, and New Guinea.
Phalotris is a genus of snakes of the subfamily Dipsadinae. All species of the genus Phalotris are found in South America. The specific name, mertensi, is in honor of German herpetologist Robert Mertens. The specific name, normanscotti, is in honor of Norman Scott, Jr., in recognition of his contribution to the knowledge of the herpetofauna of Paraguay.
