This species is known only from the Sierra Madre del Sur, Mexico, and specifically from the vicinity of Asoleadero and Carrizal de Bravo towns in north-eastern Guerrero, at around 2,600m asl. The limits of its distribution are not known.
Habitat and Ecology
It lives in moist oak-pine-fir cloud forest dominated by large bromeliad-covered oaks. It apparently needs the presence of fallen logs as daytime refuges. Reproduction is by direct development.
There is very little information; it is known from a few specimens. The species has not been recorded since its discovery in the 1960s despite repeated attempts to locate it.
Although it lives in a remote area, logging has apparently been taking place in its range, which could represent a threat to it. There is also pressure on its habitat from expanding small-scale agriculture, and in particular from fruit orchards.
It does not occur in any protected area. Further detailed studies are urgently needed to finally determine whether this species is still extant, and to understand if there are any threats to it.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of the absence of recent information on its extent of occurrence, status and ecological requirements. This species has not been located during a number of surveys.
