Taxonomic Notes: This taxon might be comprised of several species, specimens from the type locality in the highlands being very different to specimens from the main part of the range.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Javier Icochea, Claudia Azevedo-Ramos
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:This species has a confused disjunctive population distribution. In Peru it is suggested by Frost (1986) that it is known from the lower Amazonian slopes of the Andes of Perú from 600-1,000m asl. (Departamentos: Huánuco, San Martín). However Morales (1994) states that it is known only from the type locality (Roque, San Martin). Taxa assigned to C. peruvianus are also reported to occur widely along Madeira River and Rondonia state, Brazil. The type locality in Peru and Brazilian range are represented on the map until the range of this species can be better confirmed. It might occur in Bolivia (De la Riva et al. 2000).

Population [top]

Population:Abundance is not known. There is some doubt as to whether or not the Peruvian and Brazilian populations refer to the same species. Peruvian specimens are known only from museum collections.
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:In Peru it is a premontane species. In Brazil it inhabits lowland tropical moist forest. Generally a forest floor species, eggs are laid on the floor, and tadpoles are carried to small pools by the adults.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): In Peru the species is threatened by conversion of habitat to coffee plantations and other agricultural activities, and generalised logging including clear cutting. Recent surveys have indicated that it is now not present at the Peruvian type locality. There are no major threats to the species in Brazil.

Conservation Actions [top]

Conservation Actions: It is not known to occur in any protected areas in Peru. Within Brazil, it has been recorded within many conservation areas (such as national forests). Further research into the taxonomy and range of this taxon is required.
