This species is known only from the type locality of El Tambo, 31.5 km E of Canchaque, and from 12.7 km [by road] E of El Tambo, both on the western slope of the Cordillera de Huancabamba, Piura Region, Peru. It occurs at elevations from 2,770–2,820 m asl. Its total range is not known, but it is believed to be restricted to the Huancabamba region. The extent of occurrence (EOO) of its estimated geographic range is 79 km2 and all individuals are considered to occur at two separate threat-defined locations.
Habitat and Ecology
This terrestrial species can be found humid montane forest. Specimens have been found under rocks in disturbed elfin forests (Cannatella 1984). Males call from the ground at night (Duellman and Lehr 2009). Although it is not known if it occurs outside primary montane forest, it has been found along forest edges (including roads). It breeds by direct development.
It was common when collected in 1991. Its current population status is not known, but is believed to be in decline due to reductions in the extent and quality of habitat.
There is ongoing habitat loss in the vicinity of the type locality due to agricultural activities and livestock grazing.
This species has not been recorded in any protected areas.
There is a general need for further research into the fauna of the Huancabamba depression fauna. It has been suggested that a protected area should be established in the region.
Further survey work is needed to determine if it occurs outside the vicinity of the type locality. More information is needed on this species' population status, ecology, and threats.
Red List Status
Data Deficient (DD)
Listed as Endangered because of its extent of occurrence (EOO) of 79 km2, it occurs in two threat-defined locations, and there is continuing decline in the extent and quality of its habitat along the Cordillera de Huancabamba in Peru.
