Pristimantis wagteri is only known from the type locality: Ullilen (06 50' 32" S, 77 41' 50.1" W, 3000 masl) and vicinities (Los Cóndores Lake, 2870 masl), Province of Mariscal Cáceres, Department of San Martín, Peru. This area is in the northwestern corner of the department of San Martín in the northern portion of the Cordillera Central in northern Peru (Venegas, 2007).
Habitat and Ecology
The species is known to occur the humid montane forest of the Yungas eco-region. Individuals are active at night and can be found on logs on the ground and in terrestrial bromeliads, in pasture area for cattle and on rocks and bushes. Sympatric anurans include Gastrotheca ossilaginis, Pristimantis corrugatus, P. schultei, P. stictoboubonus, and Telmatobius truebae (Venegas, 2007).
A clutch of 14 white eggs presumably of P. wagteri was found among the leaves of a terrestrial bromeliad in the month of November. Abundant juveniles were found in the same area on the same day. Vocalizations of P. wagteri
sound like a little bell (Venegas, 2007).
This species is abundant at its type locality (P. Venegas, pers. comm. May 2008).
The montane forests of the northern Andes in Peru are continuously suffering destruction because of agricultural expansion and cattle grazing (Venegas, 2007).
The creation of protected areas in the ridges of the Cordillera Central is a much needed conservation action (Venegas, 2007).
In the Eleutherodactylus unistrigatus group according to the original publication. In the genus Pristimantis according to AmphibiaWeb (2008). Pristimantis wagteri is distinguished from other similar species by a combination of morphological features and colour patterns (Venegas, 2007).
