This species was formerly known only from the type locality of Tutumbaro (at 1,840 m asl) on the Río Piene, Ayacucho Region, in southern Peru. Since the previous assessment, it has also been recorded in a stream of the vicinity of Cajadela Community (at 1,837 m asl) in the Apurimac River drainage, Ayacucho Region (G. Chávez pers. comm. March 2018). The two known localities are separated by 45 km (airline). It might range much more widely, but there has been little survey work of the surrounding areas. Its extent of occurrence (EOO) is 162 km2 and all individuals occur in two threat-defined locations.
Habitat and Ecology
This species inhabits primary and secondary cloud forest (Cannatella and Duellman 1982). Individuals have been recorded calling at night from the upper sides of leaves within 1 m of a slow stream. Eggs are presumably laid on leaves, with larval development in streams. It is unknown whether it can tolerate habitat disturbance.
There is little information about its population status, as it is only known from four adult males collected in 1975 (Cannatella and Duellman 1982) and one additional individual collected in 2010 (G. Chávez pers. comm. March 2018). In 2011,
