Kingdom Phylum Class Order Family
Animalia Chordata Amphibia Anura Centrolenidae

Scientific Name: Cochranella xanthocheridia Ruíz-Carranza and Lynch, 1995
Taxonomic Source(s): Frost, D.R. 2016. Amphibian Species of the World: an Online Reference. Version 6.0 (31 March 2016). New York, USA. Available at: http://research.amnh.org/herpetology/amphibia/index.html.
Taxonomic Notes: This species is regarded as an incertae sedis within Centroleninae by Guayasamin et al. (2009). The species is very similar to Rulyrana susatamai and further taxonomic research is needed to determine the species boundaries (M. Rada pers. comm. February 2017).

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2017
Date Assessed: 2017-02-27
Assessor(s): IUCN SSC Amphibian Specialist Group
Reviewer(s): Luedtke, J.
Contributor(s): Rymel Acosta-Galvis, A., Castro, F., Lynch, J. & Rada, M.
Facilitator/Compiler(s): Hobin, L., NatureServe
Justification:
Listed as Vulnerable because its extent of occurrence (EOO) is 16,635 km2, it occurs in four threat-defined locations, and there is continuing decline in the extent and quality of its forest habitat in the Western Cordillera of Colombia.

Geographic Range [top]

Range Description:This species is endemic to Colombia. It was previously only known from the departments of Risaralda and Antioquia on the western flank of the Cordillera Occidental. However it is now also known from Municipio de Tierra Alta, Córdoba Department, in the northern section of Cordillera Occidental (Romero-Martínez 2008). It has been recorded between 480–2,060 m asl. The new EOO with the addition of the locality in Córdoba is about 16,635 km2.

Population [top]

Population:It is only known from seven specimens, five of them collected between the decades of 1980–1990 and the last two between 2004–2005. The last survey for the species near the type locality was in 2010 (M. Rada pers. comm. February 2017). There have been no recent surveys to others localities (M. Rada pers. comm. February 2017). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species occurs on vegetation next to streams in sub-Andean forests and Andean forest. It has not been recorded outside forest habitat. It lays its eggs on the top of leaves and, when hatched, the tadpoles drop into the water below where they develop further.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: There are no records of this species being utilized.

Threats [top]

Major Threat(s): The major threats are habitat fragmentation and loss due to agricultural expansion (including planting of illegal crops) and timber extraction, and water pollution. Another major threat is mining activity, which destroys forested areas and pollutes water bodies.

Conservation Actions [top]

Conservation Actions: Conservation Actions
This species has been found in Paramillo National Park and in the limits of Tatamá National Park. It was previously thought that it may occur in Orquideas National Park due to an overlap in range, however no records have been found within the park. 

Research Needed
Research in taxonomy, population trends, ecology and distribution are recommended for the species.
