Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2010
Date Assessed: 2008-03-31
Assessor(s): Ignacio De la Riva
Reviewer(s): Ariadne Angulo and Simon Stuart
Justification:
Listed as Vulnerable in view of its extent of occurrence of less than 20,000 km2, area of occupancy of less than 2,000 km2, with all individuals in fewer than ten locations, and a projected decline in the extent and quality of its habitat due to mining and climate change.

Population [top]

Population:It seems that there are two different populations of this species; however, it is not known whether these populations are conspecific with each other (I. De la Riva, pers. comm. 2008).
Current Population Trend:Unknown
Additional data:
♦ Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species is found in humid paramo habitats. Individuals can be found under stones by day. Gravid females were found to contain numerous, large, unpigmented eggs. Other anurans at the type locality are Telmatobius bolivianus and Gastrotheca marsupiata (De la Riva, 2007).
Systems:Terrestrial

Threats [top]

Major Threat(s): Mining activities can be a potential threat to the species. In addition, a restricted geographic distribution and the predicted effects of climate change (e.g. drying up of regions) are considered to pose serious threats to the species (I. De la Riva, pers. comm. 2008).
