Pristimantis rhigophilus is known from the type locality and its vicinities: Páramo de Guaramacal (9 13’ 53.9’’ N, 70 11’ 08.7’’ W, 3100 masl), on the Laguna de Los Cedros- Guaramacal road, Municipality of Boconó, Trujillo state, Venezuela. It is known to occur between 2360-3100 masl.
Habitat and Ecology
The species is found from montane rain forest to páramo. Individuals have been found under rocks in a páramo pasture-like area, with a vegetation landscape dominated by Espeletia sp. and Puya sp., a habitat that is shared with Pristimantis boconoensis. One individual was also found under a rock near a forest stream in a transition zone between cloud forest and páramo; other species found in this habitat include Atelopus sp. and Nephelobates sp. (La Marca, 2007).
This has been always a rare species to find (E. La Marca, pers. comm. 2008).
No major threats are currently known for this species.
This species occurs in Guaramacal National Park (a.k.a. General Cruz Carrillo National Park)(E. La Marca, pers. comm. 2008).
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 rhigophilus can be distinguished from other similar species by a combination of morphological characters and colour patterns (La Marca, 2007).
