This species is known from two localities in the Sierra de los Cuchumatanes in western Guatemala, at 3,200-3,395m asl.
Habitat and Ecology
All records have been from small caves, with streams flowing out of them. It is presumed that the adults live in the surrounding montane pine forest, which is now somewhat degraded.
The type series was collected in 1968. A visit to the cave where the series was collected in June 1989 turned up no individuals. The forest around the cave had been cleared, the area was heavily grazed, and the water in the stream in the cave was heavily silted. In 1995, a tadpole was found very close to the type locality in a stream that has subsequently dried up after the water was piped to the local community. In 2002, tadpoles were found at another locality (Magdalena). There are few other streams in the region and most natural habitat has been severely degraded.
The main threats to the species, as already indicated, include forest destruction (due to expanding farming and human settlements, as well as wood extraction) and deterioration of water quality. Chytridiomycosis is a potential threat, given the impact that it has had on some other members of this genus in Central America.
It occurs in the proposed Parque Nacional Cuchumatanes. Further survey work is required to determine the biology and population status and trends of this species and the limits of its range. In view of the threat of chytridiomycosis, ex-situ populations might need to be established
