Plethodontidae

Plethodontidae, or lungless salamanders, are a family of salamanders. With over 500 species, lungless salamanders are by far the largest family of salamanders in terms of their diversity. Most species are native to the Western Hemisphere, from British Columbia to Brazil. Only two extant genera occur in the Eastern Hemisphere: Speleomantes (native to Sardinia and mainland Europe south of the Alps) and Karsenia (native to South Korea).

The ensatina (Ensatina eschscholtzii) is a species complex of plethodontid (lungless) salamanders found in coniferous forests, oak woodland and chaparral from British Columbia, through Washington, Oregon, across California (where all seven subspecies variations are located), all the way down to Baja California in Mexico. The genus Ensatina originated approximately 21.5 million years ago. It is usually considered as monospecific, being represented by a single species, Ensatina eschscholtzii, with several subspecies forming a ring species.

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'''.

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.

Palaeoplethodon hispaniolae is an extinct salamander species found in Miocene Dominican amber from the Dominican Republic. It is so far the only salamander species known to have existed in the Caribbean.
