Taxonomic Notes: This species was previously included in the genus Eleutherodactylus (Crawford and Smith 2005). The rediscovery of this species in 1976 showed it to be a largely montane frog, occupying an apparently small range in the borderland of Costa Rica and Panama (Savage and Myers 2002).

Assessment Information [top]

Red List Category & Criteria: Critically Endangered (Possibly Extinct) D ver 3.1
Year Published: 2014
Date Assessed: 2013-07-14
Assessor(s): IUCN SSC Amphibian Specialist Group & NatureServe
Reviewer(s): Luedtke, J.

Facilitator/Compiler(s): Young, B.E. & Nowakowski , J.
Listed as Critically Endangered because, given recent survey efforts and lack of records, it is inferred that it is either possibly extinct or if there is still an extant population, that it is very small (<50 mature individuals). However, additional sampling effort is needed before it can be declared Extinct or re-assessed under a different criterion.
Date last seen: 1983

Population [top]

Population:It is generally a rare species. In Costa Rica, there is no information on this species after it was collected in the 19th century, despite annual sampling excursions within Talamanca since 2007 (G. Chaves and A. García pers. comm. 2013). In Panama, there have been several recent efforts to sample amphibians within the range of this species, but C. gulosus was not recorded (Hertz et al. 2012). Populations discovered in the 1970s and 1980s in the Río Chiriquí Valley of Panama may have been impacted by the construction of the Fortuna Dam (Savage and Myers 2002).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:Unknown

Habitat and Ecology [top]

Habitat and Ecology:It inhabits humid premontane forest. Little is known about the species’ biology, but it is presumed to breed by direct development.
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade:

There are no reports of this species being utilized.

Threats [top]

Major Threat(s): The main threat is general habitat loss primarily due to agriculture, ranching, and logging in parts of its range in Panama.

Conservation Actions [top]

Conservation Actions: The species has been recorded from the protected areas of Parque Internacional La Amistad and the Reserva Forestal Fortuna. Further research is needed into current threats, the range, and natural history of this species.
