This species is known only from a very restricted area near Páramo de Mucubají, Sierra de Santo Domingo, in estado Mérida, in the Venezuelan Andes, from 2,435-3,300m asl.
Habitat and Ecology
It inhabits páramo grassland and sub-páramo shrubland environments and cloud forest, the highest environments in the Venezuelan Andes, resembling alpine tundra, but with daily temperature extremes. It is usually found within grasses and frailejones (Espeletia spp.), usually along and within streams.
It has not been seen in at least a decade, and its range is very much reduced.
Introduced trout and possibly disease might be threatening this species. This species shares its habitat with Atelopus mucubajiensis, a páramo frog well known for having experienced a dramatic population decline (La Marca and Reinthaler 1994; Lotters 1996; La Marca and Lötters 1997) probably due to chytridiomycosis, and so this disease must also be suspected in C. leopardalis.
There is a population within Parque Nacional Sierra Nevada (Mérida State), in the Venezuelan Andes. Surveys are required to determine the population status of this species and whether it has been affected by disease. Given the potential risk of disease, there might be a need for the establishment of a captive-breeding programme.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because of a drastic population decline, estimated to be more than 80% over the last ten years, inferred from the apparent disappearance of most of the population (perhaps due to chytridiomycosis); and because its Area of Occupancy is less than 10 km2, all individuals are in a single location, and there is continuing decline in the number of mature individuals.
