Rhinella yanachaga is only known from the Yanachaga Chemillén National Park, Cordillera Yanachaga, Province of Pasco, Department of Pasco, Peru (Lehr et al., 2007).
Habitat and Ecology
The species can be found in cloud forest with a thick layer of moss covering the ground and tree trunks. Individuals have been found beneath a layer of moss and dirt about 10–20 cm below the surface on the side of a trail, resting on
the tops of leaves (ca. 50 cm above the ground) and in trees. Syntopic species include Phrynopus bracki, Pristimantis mendax, and P. sagittulus. One gravid female was found to contain 136 unpigmented eggs (Lehr et al., 2007).
The species was seen as recently as 2007 and 2008. It was one of the most abundant species in the area (J.C. Chaparro, pers. comm. 2008).
No major threats are known for this species.
The species occurs within the boundaries of Yanachaga Chemillén National Park (Lehr et al., 2007).
Studies on the presence of the chytrid fungus are recommended for this species (E. Lehr, pers. comm. 2008; J.C. Chaparro, pers. comm. 2008).
Tentatively assigned to the veraguensis species group. Rhinella yanachaga can be distinguished from other similar species by a combination of morphological features and colour patterns (Lehr et al., 2007).
