This species is known from the cloud forests (upper limit) and páramo ecotones from Sierra de La Culata, state of Mérida, Venezuela, between 2900 and 3300 masl (La Marca, 2007).
La Marca (2007) indicated that the locality and elevation provided in the original description (Mérida, 1600 masl) may perhaps correpond with the locality from where specimens were sent to the British Museum (city of Mérida), as no additional specimens have been found for this specific locality.
Habitat and Ecology
It is terrestrial and normally found under rocks in páramo and the ecotone of páramo/cloud forest. La Marca (2007) also indicates that individuals can be found in rock walls, in páramo close to potato crops, and in abandoned fields surrounded by cloud forest. Other anuran species found with M. briceni include Mucubatrachus culatensis and Atelopus oxyrhynchus (La Marca, 2007).
The species breeds by direct development.
It is an uncommon species.
There are no known threats to the species' habitat at present, but its restricted range renders it susceptible to stochastic threatening processes.
Populations are found within Parque Nacional Sierra de la Culata and possibly Parque Nacional Sierra Nevada.
Red List Status
Listed as Vulnerable because it is known from fewer than five locations.
La Marca (2007) recently 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.
