This species is known from the páramos of the Sierra Nevada de Santa Marta, in the department of Magdalena, Colombia. It has been recorded between 2,350 and 4,800m asl.
Habitat and Ecology
It occurs in sub-Andean and Andean forests, and páramo, and also the lower portion of snowy areas. It can adapt to some modification of its habitat. It lays egg chains in streams, where the tadpoles also develop.
Although common in the past, the species had not been seen since 1994, due to a lack of surveys in the area. It was recently rediscovered (many tadpoles and six adult males) in early February 2008, in La Serrania de Cebolleta. Two of the six adults were reported ill (Rueda Solano 2008).
The most serious threat to this species is the risk of chytridiomycosis, which has had a devastating impact on other high-altitude Atelopus species. Climate change, habitat loss caused by agriculture, and crop fumigation, are all also major threats.
Its range includes Parque Nacional Natural Sierra Nevada de Santa Marta. Surveys to determine the current population status of this species are currently underway (L.A. Rueda Solano pers. comm. 2008). A captive-breeding programme might need to be established.
We follow Coloma (2002) in considering Atelopus leoperezii as a synonym of this species.
