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).
No population status information is currently available for this species.
No major threats are known for this species.
The species is found within the Juan Pablo Peñaloza National Park (La Marca, 2007).
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).
