This species is known from Volcán Galeras (Nariño) and Páramos in southern Colombia and northern Ecuador (Carchi, Imbabura and Napo Provinces). Its altitudinal range is 3,220-4,150m asl.
Habitat and Ecology
It can be found in páramo and sub-páramo habitats. Specimens have been collected by day beneath rocks (Lynch, 1981). It occurs inside leaf axils and holes in Puya, Espeletia, and Cortadeira plants. It is presumed to be a direct development species with eggs that are deposited in moss. It occurs in secondary sub-páramo and in recently burned páramos in Ecuador.
It was collected in the mid 1990s in Colombia. It was found to be common to abundant in 2000 (Papallacta, Napo) and 2003 (El Angel, Carchi) in Ecuador.
It occurs at very high elevations above the level of serious human impact, and so it is probably not significantly threatened.
In Colombia, it occurs in the Volcán Galeras and Volcán Chiles protected areas. In Ecuador, its geographic range overlaps with Reserva Ecológica el Angel and Reserva Ecológica Cayambe-Coca.
