Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Solís, F., Ibáñez, R., Chaves, G., Savage, J., Jaramillo, C., Fuenmayor, Q. & Kubicki, B.
Reviewer(s): Stuart, S.N., Chanson, J.S., Cox, N.A. & Young, B.E.
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.

Population [top]

Population:It is considered to be rare in both Costa Rica and Panama. It is fairly common in Colombia. As of 2007, there have been no recent records of this species from Costa Rica since 1986, despite directed survey efforts (Brian Kubicki pers. comm.).
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is an inhabitant of humid lowland, premontane and montane forest. It can be observed in bushes and trees along forest streams. Larvae develop in streams. It is restricted to forest covered streams.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): In Panama the species is generally threatened by deforestation, but overall there are no major threats to the species. The causes of the decline in Costa Rica are not currently known.

Conservation Actions [top]

Conservation Actions: The species has been recorded from a number of protected areas in Costa Rica (two are volcanoes) and Panama. All known Costa Rican populations are within protected areas. It is also within a protected area in Colombia. The species appears to have disappeared in Costa Rica, and although this is marginal to the full range of the species, surveys are needed in Panama and Colombia to determine whether this decline is more widespread (Brain Kubicki pers. comm. 2007).
