This species is known only from an area at around 750-1,030m asl just north and south of Putla de Guerrero in Oaxaca, Mexico. It is likely to be more widespread.
Habitat and Ecology
Individuals have been found in a banana field and a roadside bank, suggesting some degree of tolerance to habitat disturbance. The species is the largest tropical salamander and appears to live in permanent burrows (T. Papenfuss and D. Wake, pers. comm. 2007). Its minimum viable population size may require a larger area of occupancy. This species reproduces by direct development (D. Wake, pers. comm. 2007).
There is no information available on the population status of this species. It is known only from a few specimens found on several different collection trips to the region.
Urbanization and changed agricultural practice away from shade grown coffee or increased tilling.
This species is not known from any protected areas.
