This species is known only from the vicinity of the type locality of Laguna, west slope of Serrania de Sira, Departamento Huánuco, Peru. The type specimen was recorded at 1,280m asl, but the species may well occur from 600 to around 2,000m asl (as another specimen is believed to have been found at 600m asl). It presumably ranges much more widely than has been mapped, but it is nonetheless likely to be endemic to the Serrania de Sira.
Habitat and Ecology
Their habitat is premontane and montane forest on an isolated mountain ridge of the upper Amazon Basin. Nothing is known about their breeding strategy, although it has been suggested that this may be a species that breeds by direct development. It is not known to what degree they can withstand any anthropogenic disturbance.
There is no information on the population status of this species.
Although the restricted area that the species inhabits is relatively inaccessible, there is some disturbance due to farming activity and human settlements. In addition, the lower parts of the range are being selectively logged.
This species is quite likely to occur in Reserva Comunal El Sira. Continued maintenance of this, and other remaining habitat in the Serrania de Sira, is necessary.
Red List Status
Duellman and Toft (1979) described this species from only one specimen (a female), and suggested this species could have direct development.
