This species is known from two widely separated areas along the western flank of the Cordillera Occidental in Colombia, from Chocó, Valle del Cauca, and Antioquia Departments, from 2,100-2,250m asl. The gap in the known distribution is surely a consequence of a lack of survey effort and hence it is presumed in this assessment that it occurs in between these two areas.
Habitat and Ecology
Most collectors probably never see this species or, if they do, they see it and mistake it for insect droppings. The largest specimen ever found was only 17mm long. The colouration makes the organisms very cryptic on the surface of ferns very near the tips where water collects and drips. This species has only been recorded from primary forest and from forest edges. Reproduction is by direct development.
This is a very abundant species at two localities on the Serrania de los Paraguas. However, at the only other locality from which it is known (western Antioquia) it is uncommon.
The major threats to its habitat are habitat destruction due to the cultivation of crops and livestock farming, as well as chemical pollution from spraying of the crops.
The projected range of this species includes Parque Nacional Natural Tatama and Parque Nacional de Las Orquídeas, although there are no records from these parks yet. Until collectors become familiar with the necessary collection techniques the existing data on its range will remain incomplete.
