Range Description

Pristimantis thyellus is found almost exclusively in Páramo El Batallón, state of Táchira, Venezuela, between 2900 and 3800 masl. The type locality is found within a protected area [Juan Pablo Peñaloza National Park (ca 8 10’48’’ N, 71 54’08’’ W, 3125 masl), municipality of Guaraque, state of Mérida, close to the boundary with the state of Táchira, Venezuela] (La Marca, 2007).

Habitat and Ecology

Individuals of this species can be found in shrubby páramo habitat, under rocks, on top of relatively moist soil. One individual was found close to a clutch of ca 20 x 15 cm, which contained 34 cream-yellowish eggs laid in a single egg mass (La Marca, 2007).

Listed as Data Deficient since it has only recently been described, and there is still very little known about its extent of occurrence, area of occupancy, status and ecological requirements.

Taxonomic Notes

La Marca (2007) erected the genus Mucubatrachus to accommodate species that have a dermal fold posterior to the urostyle and before the cloaca. Hedges et al. (2008), however, subsequently placed Mucubatrachus in the synonymy of Pristimantis. Pristimantis thyellus can be distinguished from other similar species by a combination of morphological characters and colour patterns (La Marca, 2007).
