Type material of Colostethus ucumari was collected at: Parque Regional Natural Ucumarí (ca 2500 m above sea level), Department of Risaralda, at approximately 4 42’ N, 75 29’ W; Hacienda El Carelia, ca. 8 km E Salento, Department of Quindío; Finca La Cristalina (2152–2250 m) ,Vereda Guamal, Pijao, Department of Risaralda; 20.3 mi WNW Cajamarca, Department of Tolima; 6 km ESE Villa María (2130 m), Department of Caldas; 5.5–6 km by road southeastward from Villa María (2320 m), Department of Caldas, Colombia (Grant, 2007).
Habitat and Ecology
Colostethus ucumari is a riparian species not known to occur more than a few meters (<3 m) from the water’s edge. Specimens were collected in grassy vegetation, on and beneath rocks along streams and pools, in both primary forest and in or at the edge of forest clearings, such as pastures and grassy roadside drainage ditches. Most specimens were
taken during diurnal collecting, although some type specimens were collected while active at night (Grant, 2007).
Information on population status is currently unavailable for this species.
No major threats are known for this species.
Colostethus ucumari is known to occur in a regional protected area, as well as outside of the confines of this area.
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).
