|Scientific Name:||Hyloscirtus colymba|
|Species Authority:||(Dunn, 1931)|
Hyla alvaradoi Taylor, 1952
|Taxonomic Notes:||This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich et al. 2005).|
|Red List Category & Criteria:||Critically Endangered A4ace ver 3.1|
|Assessor/s:||Frank Solís, Roberto Ibáñez, Gerardo Chaves, Jay Savage, César Jaramillo, Querube Fuenmayor, Federico Bolaños, Karen Lips|
|Reviewer/s:||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)|
Listed as Critically Endangered because of a drastic population decline, estimated to be more than 80% over a ten year period, inferred from ongoing rapid declines in populations infected with chytridiomycosis, and general habitat destruction and/or degradation.
|Range Description:||This species is known from the Atlantic slopes of south-eastern Costa Rica to central Panama, from sea level to 1,116m asl, and also from the Pacific slopes of eastern Panama (Savage 2002). The possible presence of this species in Colombia adjacent to eastern Panama needs to be confirmed.|

|Population:||Little is known about the population size or abundance of this species. It has disappeared from western Panama, including Reserva Forestal Fortuna (1996-97), and El Copé (2004); it is still present at low abundance in the Darien area (Roberto Ibáñez pers. comm. 2007). Remaining populations in central and eastern Panama are expected to severely decline in the near future (Karen Lips and Roberto Ibáñez pers. comm. 2007). In Costa Rica, the species has not been recorded recently, however there has been little sampling effort in the range (Federico Bolaños pers. comm. 2007).|
|Habitat and Ecology:||It inhabits cloud forest or humid lowland and montane forest, where it has been found along streams. The species breeds in swift streams; eggs are deposited under rocks, and larvae cling to rocks by means of an oral disk (Savage 2002).|
|Major Threat(s):||The declines in western Panama are probably due to chytridiomycosis (see Lips et al. 2006), and this is likely to be the most serious threat to the species. It is probably also impacted by the destruction of natural forests for the planting of crops, smallholder livestock ranching, and logging.|
|Conservation Actions:||It is known from several protected areas in Panama, and a single park in Costa Rica (Parque Internacional La Amistad). In view of the risk of chytridiomycosis, the status of this species should be closely monitored, and ex-situ populations should be established.|
