This species is known only from Filo de Caballos, in the Cerro Teotepec area of the Sierra Madre del Sur in north-eastern Guerrero, Mexico, at 2,650m asl.
Habitat and Ecology
It lives in pine-oak forests, and is terrestrial, hiding in logs and other debris. Reproduction is by direct development.
There is little information; it is known from very few collecting events. Last recorded in 2000 (T. Papenfuss, M. García-París, G. Parra-Olea, pers. comm., 2007). There is suspected to have been a significant decline in this species.
Although it lives in a remote area, logging has apparently been taking place on Cerro Teotepec, and this might constitute a threat to it. There is also pressure on this species' habitat from expanding small-scale agriculture.
It does not occur in any protected areas. Further research is needed into the population declines of this species.
Red List Status
Listed as Endangered, because recent population reductions of greater than 50% have been experienced and these declines are expected to continue. All individuals are known from a single location (presumed to be slightly greater than 100km2), which is being reduced in size and quality. The species has become very hard to locate. Increased information may in fact demonstrate Critically Endangered as a more appropriate listing.
