This species is known from a single female specimen collected in 1998 from the type locality: Quebrada Sancapech, Finca San Francisco, Huehuetenango department, Guatemala, at 1,270m asl. This locality is in the north-western portion of the Sierra de Los Cuchumatanes.
Habitat and Ecology
It is recorded from cloud forest. There is no information on breeding, although closely related species breed by larval development in tree cavities and in bromeliads.
There is no information on current population status, and three subsequent trips to the type locality have not turned up any more individuals.
Habitat loss is a threat to this species: it was found in the only small forest fragment in the area, which is surrounded by extensively cleared agricultural lands. Chytridiomycosis is also a potential threat, as other species of the genus have also declined in Guatemala due to the impacts of the disease.
It does not occur in any protected area. Further survey work is required to determine the population status of this species and the limits of its range, particularly to ascertain whether or not it might survive in forested areas outside the type locality. Given the possible threat of chytridiomycosis, surviving individuals might need to form the basis for the establishment of an ex-situ population.
This species was previously included in the genus Hyla but has recently been moved to the genus Ptychohyla (Faivovich et al. 2005).
