Pristimantis corrugatus is known from several localities at elevations of 3000–3300m asl in the regions of San Martín and Amazonas, Peru (P. Venegas, pers. comm. 2008). This area corresponds to the Cordillera Central in northern Peru (Duellman et al., 2006).
Habitat and Ecology
The species is found in very humid montane forest and in patches of elfin forest. Individuals are found on leaves of low bushes, 30–150 cm above ground at night. Sympatric species at the different localities include Colostethus sp., Pristimantis wagteri, Gastrotheca ossilaginis, Rhinella arborescandens, Centrolene lemniscatus, Pristimantis bromeliaceus, P. rufioculis, P. schultei, P. stictoboubonus, Gastrotheca ossilaginis and Telmatobius atahualpai (Duellman et al., 2006).
This species is considered to be relatively abundant (P. Venegas, pers. comm. 2008).
Enciso et al. (2008) reported Aeromonas caviae and other bacteria from skin samples, where P. corrugatus was one of the sampled species. These authors suggest that there is a potential for infection and development of the disease if populations undergo stress.
It is reported to occur in the Área de Conservación Privada Huiquilla (Enciso et al., 2008).
In the Eleutherodactylus orestes group according to the original publication. In the genus Pristimantis according to Heinicke et al. (2007). Pristimantis corrugatus is distinguished from other similar species by a combination of morphological features and colour patterns (Lehr and Duellman, 2007).
