Ungaliophis continentalis, or the Chiapan boa, is a species of nonvenomous snake in the family Tropidophiidae. [1] It is endemic to Mexico, Guatemala, and Honduras. [2]
The Boidae, commonly known as boas or boids, are a family of nonvenomous snakes primarily found in the Americas, as well as Africa, Europe, Asia, and some Pacific islands. Boas include some of the world's largest snakes, with the green anaconda of South America being the heaviest and second-longest snake known; in general, adults are medium to large in size, with females usually larger than the males. Six subfamilies comprising 15 genera and 54 species are currently recognized.
The Crotalinae, commonly known as pit vipers, or pit adders, are a subfamily of vipers found in Eurasia and the Americas. Like all other vipers, they are venomous. They are distinguished by the presence of a heat-sensing pit organ located between the eye and the nostril on both sides of the head. Currently, 23 genera and 155 species are recognized: These are also the only viperids found in the Americas. The groups of snakes represented here include rattlesnakes, lanceheads, and Asian pit vipers. The type genus for this subfamily is Crotalus, of which the type species is the timber rattlesnake, C. horridus.
The Typhlopidae are a family of blind snakes. They are found mostly in the tropical regions of Africa, Asia, the Americas, and all mainland Australia and various islands. The rostral scale overhangs the mouth to form a shovel-like burrowing structure. They live underground in burrows, and since they have no use for vision, their eyes are mostly vestigial. They have light-detecting black eye spots, and teeth occur in the upper jaw. Typhlopids do not have dislocatable lower jaw articulations restricting them to prey smaller than their oral aperture. The tail ends with a horn-like scale. Most of these species are oviparous. Currently, 18 genera are recognized containing over 200 species.
The Anomalepididae are a family of nonvenomous snakes, native to Central and South America. They are similar to Typhlopidae, except that some species possess a single tooth in the lower jaw. Currently, four genera and 15 species are recognized. Common names include primitive blind snake and dawn blind snake.
The Aniliidae are a monotypic family created for the monotypic genus Anilius that contains the single species Anilius scytale. Common names include the American pipe snake and false coral snake. It is found in South America. This snake possesses a vestigial pelvic girdle that is visible as a pair of cloacal spurs. It is ovoviviparous. It is non-venomous, and its diet consists mainly of amphibians and other reptiles. Two subspecies are recognized, including the nominate subspecies described here.
The Bolyeriidae are a family of snakes native to Mauritius and a few islands around it, especially Round Island. They also used to be found on the island of Mauritius, but were extirpated there due to human influence and foraging pigs in particular. These snakes used to be placed in the Boidae, but are now classed as a separate family. Two monotypic genera are recognized, but only a single species is extant. Bolyeriidae appear to be most closely related to the Asian genus Xenophidion.
Xenopeltis, the sunbeam snakes, are the sole genus of the monotypic family Xenopeltidae, the species of which are found in Southeast Asia. Sunbeam snakes are known for their highly iridescent scales. Three species are recognized, each one with no subspecies. Studies of DNA suggest that the xenopeltids are most closely related to the Mexican burrowing python and to the true pythons (Pythonidae).
The Tropidophiidae, common name dwarf boas or thunder snakes, are a family of nonvenomous snakes found from Mexico and the West Indies south to southeastern Brazil. These are small to medium-sized fossorial snakes, some with beautiful and striking color patterns. Currently, two living genera, containing 34 species, are recognized. Two other genera were once considered to be tropidophiids but are now known to be more closely related to the boids, and are classified in the subfamily Ungaliophiinae. There are a relatively large number of fossil snakes that have been described as tropidophiids, but which of these are more closely related to Tropidophis and Trachyboa and which are more closely related to Ungaliophis and Exiliboa is unknown.
The Boinae are a purported subfamily of boas found in Central and South America, as well as the West Indies. In the Integrated Taxonomic Information System (ITIS), Boinae is considered an invalid synonym of Boidae.
Typhlops is a genus of blind snakes in the family Typhlopidae. The genus is endemic to the West Indies. Some species which were formerly placed in the genus Typhlops have been moved to the genera Afrotyphlops, Amerotyphlops, Anilios, Antillotyphlops, Argyrophis, Cubatyphlops, Indotyphlops, Letheobia, Madatyphlops, Malayotyphlops, and Xerotyphlops.
Ramphotyphlops is a genus of nonvenomous blind snakes of the family Typhlopidae. Member species of the genus are native to southern Asia and southeast Asia, as well as many islands in the southern Pacific Ocean. They occur in a wide variety of habitats. Currently, 22 species are recognized as being valid.
Ungaliophis is a genus of dwarf boas found from southern Mexico to Colombia. Currently, two species are recognized.
Rhinotyphlops is a genus of blind snakes in the family Typhlopidae. The genus is found in Africa, the Middle East, and India. Some species formerly assigned to the genus Rhinotyphlops have been moved to the genera Afrotyphlops and Letheobia.
Ungaliophis panamensis, or the Panamanian dwarf boa, is a species of nonvenomous snake in the family Tropidophiidae. It is native to Nicaragua, Costa Rica, Panama, and Colombia. Adults measure up to 50 cm (20 in) in length, with males being slightly larger but less massive than females. Its diet is not entirely known, but it has been observed feeding on bats, birds and geckos.
Liotyphlops albirostris is a species of snake in the Anomalepididae family. It is endemic to Central America. The snake has been reported from Colombia, Curaçao, Panama and Venezuela.
The Sudan blind snake is a species of snake in the family Leptotyphlopidae.
Sundatyphlops polygrammicus, also known as the Lesser Sunda blind snake or north-eastern blind snake is a species of snake in the Typhlopidae family.
Letheobia sudanensis, also known as the Garamba gracile blind snake or Sudan baked snake, is a species of snake in the Typhlopidae family. It is endemic to Africa.
The wedge-snouted blind snake, also known as the wedgenose blind snake, is a species of snake in the Typhlopidae family.
