Geographic Occurrence

Natural Resident: Ecuador, Peru


In the Phrynopus flavomaculatus group. Phrynopus parkeri and Phrynopus pereger (now Eleutherodactylus pereger) may be synonyms according to Lynch, 1975, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 35: 34. Almendáriz C. and Orcés, 2004, Rev. Politécnica, Quito, 25: 132-133, provided distributional data for Ecuador. Lehr, 2006, Herpetologica, 62: 338, transferred this species to the Eleutherodactylus nigrovittatus group. Heinicke, Duellman, and Hedges, 2007, Proc. Natl. Acad. Sci. USA, 104: 10092-10097, removed this species from nominal Eleutherodactylus but did not provide a new generic name. See comment by Lehr, 2006, Herpetologica, 62: 338. See photograph, map, description of geographic range and habitat, and conservation status (as Phrynopus flavomaculatus) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 405. See Duellman and Lehr, 2009, Terrest.-breeding Frogs in Peru: 87-88, for brief account. See account by Motta, Chaparro, Pombal, Guayasamin, De la Riva, and Padial, 2016, Herpetol. Monogr., 30: 124–126. Székely, Eguiguren, Ordóñez-Delgado, Armijos-Ojeda, and Székely, 2020, PLoS One, 15(9: e0238306): 9–10, noted that the advertisement call is unknown, and suggested on molecular grounds that the nominal species is a complex of at least 4 species, with the Peru specimen in particular noted as likely distinct.
