Atelopus pachydermus (Schmidt, 1857)

Class: Amphibia > Order: Anura > Family: Bufonidae > Genus: Atelopus > Species: Atelopus pachydermus

Phirix pachydermus Schmidt, 1857, Sitzungsber. Akad. Wiss. Wien, Phys. Math. Naturwiss. Kl., 24: 15. Holotype: KM 1013/1356, according to Savage, 1970, Proc. California Acad. Sci., Ser. 4, 38: 273–288. Type locality: "Neu Grenada"; later restricted by Schmidt, 1858, Denkschr. Akad. Wiss. Wien, Math. Naturwiss. Kl., 14: 257, to "Westen von Neu-Grenada, bei Bonaventura, in einer Höhe von 5000′" [Polish feet, therefore = 1150 m, according to Savage, 1970, Proc. California Acad. Sci., Ser. 4, 38: 273–288] sehr salten"; see Rivero, 1968, Caribb. J. Sci., 8: 23, who noted that type locality was dubious. Lötters, 1996, Neotrop. Toad Genus Atelopus: 39, suggested that the type locality was in error and noted that the nominal collector of the type material had likely not visited the region of the stated type locality. Coloma, Lötters, Duellman, and Miranda-Leiva, 2007, Zootaxa, 1557: 4, discussed the problem and suggested that the likely type localiy is one of two towns named Buenaventura, both in eastern Panama, in the province of Panamá.

Natural Resident: Ecuador, Peru


See Rivero, 1965, Caribb. J. Sci., 5: 138, and Peters, 1973, Smithson. Contrib. Zool., 145: 34–37, for accounts. In the Atelopus ignescens group of Lynch, 1993, Alytes, 11: 77–87. Reported from humid montane forests in the Departamentos of Amazonas, Cajamarca, and La Libertad, Peru, by Rodríguez, Córdova, and Icochea, 1993, Publ. Mus. Hist. Nat. Univ. Nac. Mayor San Marcos, 45: 6. Almendáriz C. and Orcés, 2004, Rev. Politécnica, Quito, 25: 106–107, provided distributional data for Ecuador. Coloma, Lötters, Duellman, and Miranda-Leiva, 2007, Zootaxa, 1557: 1–32, provided an account, revised the species and its range, and noted that the records for La Libertad, Peru, were based on misidentification (subsequently shown to be Atelopus patazensis by Venegas, Catenazzi, Siu-Ting, and Carrillo, 2008, Salamandra, 44: 173). See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 172. Lötters, 2005, in Rueda-Almonacid et al. (eds.), Ranas Arlequines: 97, provided a brief account, photograph, and map.
