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.
