Population [top]

Population:It has always been a rare species. It was not found during the Rapid Assessment Program (RAP) expeditions of 1993, 1999 and 2003 to the Cordillera del Condór region. However, its range is in a poorly explored area, and so its population status remains unclear.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species' range lies within pluvial premontane forest and very humid premontane forest. The annual mean temperature is 18-24°C in both zones. The annual mean precipitation is 4,000-8,000mm in the pluvial premontane forest and 2,000-4,000mm in the very humid premontane forest (data updated from Coloma 1995). Reproduction probably takes place by females laying eggs on the ground, with the males bringing larvae to streams for development.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Habitat destruction and degradation due to agricultural development and logging are threats to this species. It is possibly also threatened by introduced species.
