This species is known only from the type locality, Finca Primavera, in the municipality of El Tambo, in Cauca Department, on the Pacific slope of the Cordillera Occidental in Colombia, at 1,400m asl.
Habitat and Ecology
It occurs on the ground near streams in sub-Andean forests, and it has not been recorded outside forest habitat. Its breeding habits are not known but presumably are similar to other species of the genus, with the larvae being carried to streams to develop.
There is no information on the population status of this species, which is only known from a few specimens.
The major threats for this species are not known specifically, but presumably include habitat loss and fragmentation due to the expansion of cattle raising, timber extraction, cultivation of illegal crops and water pollution.
The type locality is not within a protected area. More research into this species' extent of occurrence, ecological requirements and population status is needed, in particular to determine if it occurs outside the vicinity of the type locality.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing doubts as to its taxonomic validity, extent of occurrence, status and ecological requirements.
This species is potentially conspecific with Colostethus fraterdanieli (Grant and Castro 1998).
