Erythrolamprus zweifeli, the braided ground snake or Zweifel's ground snake, is a species of snake in the family Colubridae. The species is found in Venezuela and Trinidad. [2]
Erythrolamprus zweifeli belongs to the genus Erythrolamprus , which contains over 50 species. The genus Erythrolamprus belongs to the subfamily Dipsadinae, which is sometimes referred to as the family Dipsadidae.
Erythrolamprus zweifeli was previously considered to be a subspecies of Erythrolamprus reginae and called Erythrolamprus reginae zweifeli. However, based on notable differences in coloration and scale counts, it is now considered to be a separate species. [3] This close relationship to Erythrolamprus reginae, as well as the relationships of Erythrolamprus species located in northern South America, can be shown in the cladogram below, based on molecular DNA analysis: [3]

Erythrolamprus zweifeli has either a salt-and-pepper dorsal pattern or a more uniform olive-green or olive-brown pattern, with a red or black belly. It has a black postocular stripe, and lacks apical pits in its scales. [3]
It lives in Venezuela and the island of Trinidad, within montane forests, often associated with stream-edges. [3]
Erythrolamprus zweifeli likely hunts along forested stream-edges, feeding on Mannophryne stream frogs, hylid frogs, Leptodactylus validus (Windward ditch frog), salamanders, Ameiva lizards, and small birds. [3]
Bothrops atrox — also known as the common lancehead, fer-de-lance, barba amarilla and mapepire balsain — is a highly venomous pit viper species found in the tropical lowlands of northern South America east of the Andes, as well as the Caribbean island of Trinidad. No subspecies are currently recognized.
Trinidad and Tobago are continental islands with a geologically very recent history of direct land bridge connection to South America. As a result, unlike most of the Caribbean Islands, Trinidad and Tobago supports a primarily South American flora and fauna and has greater diversity of plant and animal species than the Antilles. However, rates of endemism are lower than in the rest of the Caribbean because there has been less time for genetic isolation from mainland populations because of the history of land bridge connections and hence fewer opportunities for speciation, and so a greater proportion of the species in Trinidad and Tobago are also found on the South American mainland. Trinidad is nearer to mainland South America and has been directly connected to the mainland via land bridges more often and for longer periods than Tobago. This, as well as Trinidad's larger size and more varied topography and hydrology compared to that of Tobago allow greater species and ecosystem diversity on the former compared to that on the later of the islands.
Chironius multiventris, commonly known as the long-tailed machete savane, is species of colubrid snake.
Atractus trilineatus, commonly known as the three-lined ground snake, is a species of small burrowing snake in the family Colubridae. The species is native to South America.
Oxyrhopus petolarius, commonly known as the forest flame snake, is a species of mildly venomous snake in the family Colubridae. The species is endemic to Central and South America. There are three recognized subspecies.
The royal ground snake is a species of snake in the family Colubridae. The species is endemic to northern South America.
Erythrolamprus cobella, commonly known as the mangrove snake, is a species of small semi-aquatic snake, which is endemic to South America.
Erythrolamprus ocellatus, commonly known as the Tobago false coral snake, red snake, or doctor snake is a species of colubrid snake, which is endemic to the island of Tobago.
Erythrolamprus bizona, commonly known as the double-banded false coral snake, is a species of colubrid snake, which is found in northern South America and Central America.
Erythrolamprus aesculapii, also known commonly as the Aesculapian false coral snake, the South American false coral snake, and in Portuguese as bacorá, or falsa-coral, is a species of mildly venomous snake in the family Colubridae. The species is endemic to South America.
The terciopelo is a highly venomous species of New World pit viper, found at low to moderate elevations, from northeastern Mexico through Central and South America, where it is known to inhabit elevations as high as 2600 meters above sea level in the Colombian and Ecuadorian Andes, as well as Venezuela. With a mass of up to 6 kilograms (13 lb), and a maximal length of 2.5 metres (8.2 ft), the terciopelo is among the largest of the pit vipers. It is light to dark brown in color, often with yellowish, zig-zag patterning on either side of its body. Dubbed "the ultimate pit-viper" for its large size, fangs and potent venom yield, it has a fearsome reputation, and is one of the species responsible for the most envenomated snakebites within its range, largely due to its proximity to humans, livestock and pets. Nonetheless, like all venomous snakes, the terciopelo actively avoids all contact with humans and larger animals, with bites generally only occurring when the snake is cornered, pursued, or otherwise threatened in some capacity. No subspecies are currently recognized.
James Ray Dixon was professor emeritus and curator emeritus of amphibians and reptiles at the Texas Cooperative Wildlife Collection at Texas A&M University. He lived in El Campo, Texas, throughout most of his childhood. He published prolifically on the subject of herpetology in his distinguished career, authoring and co-authoring several books, book chapters, and numerous peer reviewed notes and articles, describing two new genera, and many new species, earning him a reputation as one of the most prominent herpetologists of his generation. His main research focus was morphology based systematics of amphibians and reptiles worldwide with emphasis on Texas, US, Mexico, Central America, and South America, although bibliographies, conservation, ecology, life history and zoogeography have all been the subjects of his extensive publications.
Main Ridge is the main mountainous ridge on the island of Tobago, Trinidad and Tobago. It is a 29-kilometre (18 mi) chain of hills which runs from southwest to northeast between the Caribbean Sea and the Southern Tobago fault system and reaches a maximum height of 572 m (1,877 ft). The Main Ridge Forest Reserve, which was legally established in 1776, is one of the oldest protected areas in the world. It is a popular site for birdwatching and ecotourism. Main Ridge provides important habitat for native plants and animals, including several species endemic to Tobago.
Erythrolamprus is a genus of colubrid snakes native to Central America, the Caribbean, and South America. They include the false coral snakes, which appear to be coral snake mimics.
The scaled dove, also known as scaly dove, Ridgway's dove, mottled dove, and South American zebra dove, is found in Brazil, Bolivia, Argentina, Colombia, French Guiana, Paraguay, Trinidad and Tobago, and Venezuela. Its natural habitats are subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, subtropical or tropical seasonally wet or flooded lowland grassland, and heavily degraded former forest.
