This species is known from two localities on the Serrania de los Paraguas, in Valle del Cauca and Choco departments, on the Cordillera Occidental in western Colombia, from 2,100-2,250m asl.
Habitat and Ecology
This species is restricted to forest habitat, or the forest edge. It occupies exactly the same microhabitat as E. myops with which it is microsympatric. At one of the two localities, E. quantus is more abundant than E. myops, but the reverse occurs at the other locality suggesting local ecological differences. It breeds via direct development.
This species is sometimes regularly encountered and sometimes inexplicably uncommon. Its very small size probably explains its rarity in collections.
The habitat of the species is relatively unthreatened at present, although if a planned road is built this will present a major threat to the species' habitat.
The range of this species does not include any protected areas; however, there are ongoing efforts promoting the creation of a formal protected area that would include the Serrania de los Paraguas. This species requires close population monitoring given that it has such a restricted range.
