It is endemic to Oaxaca, Mexico, and is known from Cerro de Humo and Sierra de Juárez. Its natural habitat is pine-oak forest, but it also occurs in degraded habitats. It is threatened by habitat loss caused by clear-cutting and livestock grazing.
Thorius magnipes is a species of salamander in the family Plethodontidae. It is endemic to the Sierra Madre de Oaxaca of Mexico, and only known from near its type locality near Acultzingo, Veracruz. Its natural habitat is pine-oak forest. It can be found in bromeliads, leaf axils, under rocks and leaf-litter, and inside piles of wood chips. It is threatened by habitat loss caused by logging and agriculture.
Thorius minutissimus is a species of salamander in the family Plethodontidae. It is endemic to Mexico. It is known only from one site near Santo Tomás Teipan in the Sierra Madre del Sur of Oaxaca, in pine–oak forest at 2,458 meters elevation. Its extent of occurrence (EOO) is 10 km2, which represents the single location.
Thorius minydemus, commonly known as the La Hoya minute salamander, is a species of salamander in the family Plethodontidae. It is endemic to Mexico and only known from near its type locality near La Joya, Veracruz. Its natural habitats are cloud and pine-oak forests with many bromeliads.
Thorius munificus is a species of salamander in the family Plethodontidae. It is endemic to Mexico and only known from near its type locality near Las Vigas, Veracruz. Its natural habitats are pine-oak and pine forests, woodlands, and Arbutus forests with abundant shrubby and ericaceous plants. The species is threatened by habitat loss caused by logging, agriculture, and human settlement.
Thorius narisovalis is a species of salamander in the family Plethodontidae. It is endemic to Mexico.
Thorius papaloae, commonly known as the Papalo minute salamander, is a species of salamander in the family Plethodontidae. It is endemic to Mexico and only known from one locality near the village of Concepción Pápalo in Sierra Juárez, Oaxaca.
Thorius pennatulus is a species of salamander in the family Plethodontidae and one of the smallest tetrapods, with adults reaching a length of about 15 to 21 millimetres . It is endemic to the mountains of Veracruz, Mexico.
Thorius schmidti, commonly known as Schmidt's pigmy salamander, is a species of salamander in the family Plethodontidae. It is endemic to Mexico and only known from near the village of Zoquitlán in the Sierra Madre de Oaxaca of southern Puebla, possibly also from Oaxaca. It is named after Karl Patterson Schmidt, American herpetologist.
Thorius smithi, commonly known as Smith's salamander, is a species of salamander in the family Plethodontidae. It is endemic to Mexico and only known from near the towns of Vista Hermosa and Metates in Sierra Juárez, Oaxaca. Its natural habitats are cloud and tropical forests where it occurs on the ground under rocks and logs. It is a very rare species known only from two locations, despite attempts to find it. Presumably, habitat loss caused by logging and expanding agricultural development are threats to its forest habitat.
Thorius troglodytes, commonly known as Taylor's pigmy salamander, is a species of salamander in the family Plethodontidae that is endemic to Mexico.
