From the IUCN Red List Species Account:

 

Range Description

It is known from the Cordillera Central in the Departments of Quindío and Caldas, Colombia (Grant 2007). It occurs at elevations ranging from 2,100–2,500 m Asl. The locality from Tolima Department is actually located in Quindío (D. Mejía and W. Bolívar pers. comm. 2016). Its EOO is 833 km2 and it occurs in three to five threat-defined locations.

Habitat and Ecology

This species inhabits cloud forest. It is a riparian species and is only known to occur less than 3 m from the water. Specimens have been collected in grassy vegetation or on and beneath rocks, always along streams and puddles. It is an egg laying species and tadpoles are transported on the backs of males to the water bodies (Grant 2007).

Population

This species is rare and it has not been recorded since 1996, despite recent surveys searching for the species (D. Gómez, D. Mejía, W. Bolívar pers. comm. 2016).

Population Trend

unknown

Major Threats

Major threats include habitat loss due to agriculture activities, cattle grazing and possibly predation by rainbow trout (Oncorhynchus mykiss). These threats occur throughout its entire range. Also, chytrid fungus has been reported in the range, but there is no direct information as to whether chytridiomycosis was the cause of the decline of the species (D. Mejía and B. Wilmar pers comm. 2016).

Conservation Actions

Conservation Actions
This species is known to occur Parque Natural Regional La Pastora. 

Conservation Needed
Improved protection of its cloud forest and stream habitats is required.

Research Needed
More information is needed on this species' distribution, population status, ecology, and threats. Further survey work is necessary to determine whether the species is still extant.

Red List Status

Endangered (EN)

Rationale

Listed as Endangered because of its extent of occurrence (EOO) of 833 km2, it occurs in three to five threat-defined locations, and there is a continuing decline in the area and quality of its habitat due to agriculture activities, cattle grazing and possibly predation by the rainbow trout throughout its range.

Taxonomic Notes

Colostethus ucumari can be distinguished from other Colostethus by means of morphological differences and colour patterns; it is also the second species of Colostethus known to possess skin toxins (Grant 2007).
