This species is known from three localities in the northern part of the Cordillera Occidental in Peru. Two localities are at altitudes of 3,050 and 3,200m asl on the road between Cajamarca and Celendin (on the eastern slopes of Abra Comulica); the third locality at 3,760m asl is north of Cajamarca. Its range is not completely known, and it is difficult to estimate if this species has a much larger range. There have been very few surveys of the region.
Habitat and Ecology
This is a little-known species found in montane grassland. All individuals have been collected under stones by day. Those from 3,050m asl were in a wet grassy area, whereas the individual from 3,200m asl was in tussocks. The only specimen at 3,760m asl was collected under a rock in a grassy region by day. It is presumed to be a direct developing species.
Three adult females were used to describe it.
A general threat in the area, which might also be impacting this species, is agricultural development (principally potato cultivation).
This species is not known from any protected areas.
