Desmognathus is a genus of lungless salamanders in the family Plethodontidae known as dusky salamanders. They range throughout the eastern United States as far west as Texas, and north to southeastern Canada.
Bolitoglossa is a genus of lungless salamanders, also called mushroom-tongued salamanders, tropical climbing salamanders, or web-footed salamanders, in the family Plethodontidae. Their range is between northern Mexico through Central America to Colombia, Venezuela, Ecuador, Peru, northeastern Brazil, and central Bolivia. Neotropical salamanders of the Bolitoglossa make up the largest genus in the order Caudata, consisting of approximately one-fifth of all known species of salamanders. Adult salamanders range anywhere from 45mm to 200mm in length depending on their specific species. They are notorious for their ability to project their tongue at prey items, as indicated from their name. They are also known for their webbed feet, having significantly more webbing than any other species outside their genus with the exception of the cave-dwelling Mexican bolitoglossine Chiropterotriton magnipes. Although webbed feet are a common characteristic of these salamanders, only about half of the species in this genus contain webbed feet.
Bradytriton is a monotypic genus of salamanders in the family Plethodontidae. it is represented by the species Bradytriton silus, commonly known as the Finca Chiblac salamander, and has been considered the sister taxon of the genus Oedipina. It is found in north-western Guatemala and in Chiapas, south-eastern Mexico.
Chiropterotriton, also known as splayfoot salamanders or flat-footed salamanders, is a genus of salamanders in the family Plethodontidae. The genus is endemic to Mexico.
Cryptotriton is the genus of hidden salamanders in the family Plethodontidae, native to Mexico, Honduras and Guatemala. Most species in this genus are endangered or critically endangered with Cryptotriton sierraminensis being data deficient according to the IUCN.
Dendrotriton megarhinus, also known as the longnose bromeliad salamander or long-nosed bromeliad salamander, is a species of salamander in the family Plethodontidae. It is endemic to southwestern Chiapas, Mexico, where it is only known from the Cerro Tres Picos, the type locality.
Dendrotriton rabbi, commonly known as the Guatemalan bromeliad salamander, is a species of salamander in the family Plethodontidae. It is endemic to Guatemala and is known from the Montañas de Cuilco, near the Mexican border, and from the Sierra de los Cuchumatanes. Its range might extend into Mexico.
Gyrinophilus, the spring salamanders, are a genus of salamanders in the family Plethodontidae. The genus is endemic to the Appalachian Mountains of the eastern United States and Canada. Their habitat is under rocks in cold, clear springs, in wet caves, and in streams in forested areas.
Hydromantes, commonly referred to as web-toed salamanders, is a genus of the lungless salamander family, Plethodontidae; they achieve respiration through their skin and the tissues lining their mouth. They are endemic to mountains of California in the United States. Salamanders of this genus are distinguished in having extremely long tongues that they can project to 80% of their body length. Similar species endemic to southern France and Italy are now classified in a distinct genus, Speleomantes.
Nototriton, commonly referred to as moss salamanders is a genus in the salamander family Plethodontidae, which is characterized by their absence of lungs; they instead achieve respiration through their skin and the tissues lining their mouth. They range from Central Costa Rica to north-central and western Honduras reaching also to eastern Guatemala.
Nyctanolis is a monotypic genus of salamanders in the family Plethodontidae. It is represented by the species Nyctanolis pernix, also commonly referred to as nimble long-limbed salamander, which is characterized by its absence of lungs; it instead achieves respiration through its skin and the tissues lining the mouth. It is found in Guatemala and Mexico. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Oedipina is a genus of lungless salamanders, which is characterized by their absence of lungs; they instead achieve respiration through their skin and the tissues lining their mouth. Species of Oedipina are endemic to Honduras, Colombia, Costa Rica, Ecuador and Mexico. The common name of worm salamanders derives from the species' extraordinarily slender form with tiny limbs and digits.
Parvimolge is a genus of salamanders in the family Plethodontidae, the lungless salamanders. It is currently considered as monotypic, although this may yet change as molecular data suggest that it is embedded within a paraphyletic Pseudoeurycea. Parvimolge townsendi is endemic to the northern Sierra Madre de Oaxaca in central and southern Veracruz, Mexico, between 900 and 1900 meters elevation. It is represented by the species Parvimolge townsendi, commonly known as Townsend's dwarf salamander.
Pseudoeurycea is a genus of salamander in the family Plethodontidae. The members of this genus are commonly known as the false brook salamanders. They are found in Mexico and Guatemala.
Pseudotriton is a genus of salamanders in the family Plethodontidae. They are endemic to eastern and southern United States, from New York south to Florida and west to southern Ohio, Kentucky, Tennessee, and eastern Louisiana. They are commonly known as red salamanders or mud salamanders.
Thorius arboreus, commonly known as the arboreal minute salamander, is a species of salamander in the family Plethodontidae. It is endemic to Sierra de Juarez, Oaxaca, Mexico. The specific name arboreus, derives from the Latin word arbor, meaning tree, referring to the arboreal habitat of this species.
Thorius, also known as minute salamanders, pigmy salamanders, or Mexican pigmy salamanders, is a genus of salamanders in the family Plethodontidae. They are endemic to Mexico and found in southern Veracruz and Puebla to Guerrero and Oaxaca.
Aquiloeurycea is a genus of salamanders in the family Plethodontidae. They are endemic to Mexico. The genus corresponds to the former "Pseudoeurycea cephalica species group", which was established in order to preserve Ixalotriton and Bolitoglossa while avoiding paraphyly of Pseudoeurycea.
Isthmura is a genus of salamanders in the family Plethodontidae. They are endemic to Mexico. The genus, which corresponds to the former "Pseudoeurycea bellii species group" and was first described as a subgenus of Pseudoeurycea, was raised to full generic level in 2015 in order to preserve Ixalotriton and Bolitoglossa while avoiding paraphyly of Pseudoeurycea.
