This species is known only from the type locality, Río Iscozacín (a tributary of the Río Palcazú, in the Pachitea drainage), Pasco Department, Peru, at 400m asl. While it is not believed to be endemic to a specific area, recent surveys in nearby areas have not revealed this species (Icochea pers comm).
Habitat and Ecology
This species has been collected in lowland tropical rainforest. There is no information on its breeding habits, although the larvae presumably develop in water.
It is presumed to be very rare, and it is 30 years since it was last recorded.
It is threatened by habitat loss due to agricultural activities taking place within its range. The type locality was converted to agricultural use, and there is also dense cattle ranching.
It was known to occur in the buffer zone of the Bosque de Protección San Matías-San Carlos, but a species conservation programme is urgently needed.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of the absence of recent information on its extent of occurrence, status and ecological requirements.
