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 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 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 and only known from near its type locality, Cerro San Felipe, Oaxaca. Its natural habitats are cloud forests and mixed forests. It lives under bark or under fallen trees.
Thorius omiltemi is a species of salamander in the family Plethodontidae. It is endemic to the area around Omiltemi in the Sierra Madre del Sur of Guerrero, Mexico, at elevations of 2,500–2,950 m (8,200–9,680 ft) asl.
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 pulmonaris, commonly known as the lower cerro pigmy salamander or Cerro San Felipe salamander, is a species of salamander in the family Plethodontidae. It is endemic to Oaxaca, 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 the mountains near the village of Zoquitlán in 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 spilogaster, commonly known as the spotted thorius, is a species of salamander in the family Plethodontidae. It is endemic to Mexico and only known from the south and southeast flanks of Pico de Orizaba in central Veracruz, at elevations of 2,500–2,725 m (8,202–8,940 ft) asl.
