The type locality was originally considered to be near Juliaca, Puno, Peru. However, the dry habitats of this area are not considered to be suitable for species of the genus Phrynopus sensu lato (De la Riva et al. 2008). In addition, there are suggestions that specimens collected by the original species collector came from the vicinity of the Inca Mine in Santo Domingo, a cloud forest locality at 1,690 m asl on the Andean Amazonian slopes in the Province of Carabaya, northern Puno (De la Riva et al. 2008). Whether specimens were collected at this locality or along the route between Santo Domingo and Juliaca is unknown (De la Riva et al. 2008); thus, the location of the type locality is unclear and this species' range cannot be mapped at this time.
Habitat and Ecology
No habitat and ecology information is currently available for this species. Presumably it breeds by direct development.
No population status information is currently available for this species.
Individuals of Psychrophrynella usurpator were traditionally misidentified as Phrynopus peruvianus (now = Noblella peruviana) (De la Riva et al. 2008). The assessment for Phrynopus peruvianus, that previously appeared on the IUCN Red List is now more correctly placed under Psychophrynella usurpator.
