The major threat is habitat loss due to expanding agriculture and human settlements, and also logging.

Álvarez del Toro’s hidden salamander (Cryptotriton alvarezdeltoroi), also known as Álvarez del Toro’s salamander is a species of salamander in the family Plethodontidae. It is endemic to Mexico where it is known from its type locality near Jitotol as well as a nearby site on the Mexican Plateau in the Chiapas state.

The specific name, alvarezdeltoroi, is in honor of Mexican herpetologist Miguel Álvarez del Toro.

The dorsum and tail are a reddish brown with an irregular, obscure dorsal stripe. The limbs are orange. The snout is blunt with forward-pointing nostrils. Its natural habitat is very moist cloud forest at elevations of 1,200–1,550 m (3,940–5,090 ft) asl. It has also been found at roadsides.
