This species is known from the type locality, stated to be "toma de agua de Mapararí" in the municipality of Federación, in Sierra de Churuguara, in the state of Falcón, Venezuela (approx. 10.47N, 69.25W), where it has been recorded around 800m asl. An additional population in Parque Nacional Cueva de la Quebrada del Toro was found in May 2002 (J. Manzanilla pers. comm.).
Habitat and Ecology
It is a terrestrial, diurnal frog found in deciduous lower montane tropophilous forests. The larvae are presumably carried on the backs of the males to streams, as with other members of the genus.
There has been an observed decline in the population of this species. However, in May 2002, specimens were collected at the type locality and a new population was also found in Parque Nacional Cueva de la Quebrada del Toro.
Habitat loss and degradation, due primarily to agriculture (crops and livestock), and general disturbance by humans, is the main threat. Water extraction is a threat at the type locality. Pollution and/or parasites might be causing what appear to be problems in the development or incomplete development of the limbs. It is potentially at risk from chytridiomycosis.
It occurs in the Parque Nacional Cueva de la Quebrada del Toro. Survey work is necessary to determine the population status and trends of this species. Captive breeding might be required if the risk of chytridiomycosis proves real.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because its Extent of Occurrence is less than 100km2 and its Area of Occupancy is probably less than 10km2, its range is severely fragmented, and there is a continuing decline in the extent and quality of its habitat, and in the number of mature individuals.
