This species is known from about a dozen localities; Paramos on the Nudo de Pasto and the southern end of the Central Cordillera in Colombia (from 2,900-3,275m asl), Paramo de Purace, on the occidental slope of the central Cordillera in the department of Cauca from 2,900-3,000m asl, the department of Nariño: Laguna de la Concha, Paramo del Tabano, Pasto. The range of this species might extend in to Ecuador (but has not yet been recorded), since the habitat is the same beyond the border.
Habitat and Ecology
It is usually found on vegetation in páramo to sub-páramo and upper Andean forest. It is active mostly at night or at sundown. When inactive during the day, it occurs under rocks, logs and among dense grasses. It breeds by direct development. It has not been collected from anthropogenic habitats.
It is a common species.
Habitat loss caused by deforestation, agricultural development, and illegal crops are only localized threats, but there are no major threats to the species overall at present.
The species' distribution includes National Natural Park Purace.
