Description Edalorhina nasuta can be distinguished from its sister taxon E. perezi by the shape and characters of the head. Edalorhina nasuta has a long, pointed, fleshy snout and weakly pronounced eyelid tubercles, while E. perezi has a short, rounded snout and very prominent tubercles on the upper eyelid (Duellman and Morales 1990). Edalorhina nasuta also has a different patterning on its back, with the warts forming an “X” pattern as opposed to parallel lines (if warts are present) in E. perezi (Dunn 1949). Distribution and Habitat Country distribution from AmphibiaWeb's database: Peru
Edalorhina nasuta is found in central Peru, in Huancabamba, Pasco Department, and Huánuco Department. Its elevational range is 220 - 1000 meters above sea level (Angulo et al. 2004). Life History, Abundance, Activity, and Special Behaviors Edalorhina nasuta is terrestrial, inhabiting the leaf litter of lowland rainforests. The species is rarely seen by humans, so little is known about its life history. Based on its close relation to E. perezi, it is likely that E. nasuta deposits its eggs in foam nests alongside the edges of ponds (Angulo et al. 2004). Trends and Threats Possible reasons for amphibian decline General habitat alteration and loss Comments The species authority for E. nasuta is George Albert Boulenger, 1912 (Boulenger 1912; Angulo et al. 2004). The species epithet, “nasuta,” is Latin for "long-nosed". Edalorhina nasuta is the sister taxon to E. perezi, the only other member of Edalorhina. The closest relatives of the genus, Edalorhina, are the genera Physalaemus and Pleurodema (Lourenço et al. 2000). The two specimens use to describe E. nasuta in Duellman and Morales (1990) were collected in 1922.
