Its common name is Roberts' false brook salamander. The specific name robertsi honors the collector of the holotype, H. Radclyffe Roberts from the Philadelphia Academy of Sciences.
Pseudoeurycea smithi, commonly known as Smith's false brook salamander, is a species of salamander in the family Plethodontidae. It is endemic to certain mountainous regions of Mexico. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Pseudoeurycea unguidentis is a species of salamander in the family Plethodontidae. It is endemic to northern Oaxaca, Mexico, where it is known from its type locality, Cerro San Felipe in the Sierra Madre de Oaxaca, and some other mountains, although the identity of animals from these other locations is uncertain. Its common names are claw-toothed salamander, clawtooth false brook salamander, and clawtoed false brook salamander.
Thorius boreas, commonly known as the boreal thorius, is a species of salamander in the family Plethodontidae. It is endemic to Oaxaca, Mexico, and only known from the Sierra Juárez. Its natural habitats are pine-oak and fir forests, often at forest edges. It is threatened by habitat loss (logging), although it does explain the dramatic decline that this species has seen.
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.

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.
