Class: Amphibia > Order: Anura > Superfamily: Brachycephaloidea > Family: Strabomantidae > Subfamily: Pristimantinae > Genus: Pristimantis > Species: Pristimantis altamazonicus

Eleutherodactylus altamazonicus Barbour and Dunn, 1921, Proc. Biol. Soc. Washington, 34: 161. Holotype: MCZ 2028, by original designation. Type locality: "Upper Amazon and probably collected by the Thayer Expedition at Nauta", Departamento Loreto, Peru.

Eleutherodactylus (Eleutherodactylus) altamazonicus — Lynch, 1996, in Powell and Henderson (eds.), Contr. W. Indian Herpetol.: 154; Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 219.

Pristimantis (Pristimantis) altamazonicus — Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 128.

Common Names

Amazon Robber Frog (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 72).

Distribution

Amazonian Colombia, Peru, and Ecuador, possibly Brazil, and with unnamed but similar species in adjacent Bolivia and Brazil.

Geographic Occurrence

Likely/Controversially Present: Brazil

Comment

Duellman, 1978, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 65: 87–88, provided a brief account, including a brief description of the call. Distribution discussed by Lynch, 1980, Am. Mus. Novit., 2696: 1-24 (in the sense of including Pristimantis brevicrus). Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 55, provided a brief account for the Iquitos region of northeastern Peru as Eleutherodactylus altamazonicus. In the Eleutherodactylus (Eleutherodactylus) martinicensis series, Eleutherodactylus unistrigatus group according to Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 219. De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 57, and Köhler, 2000, Bonn. Zool. Monogr., 48: 69, consider this species possibly to occur in Bolivia. Padial, Gonzales-Álvarez, Reichle, Aguayo-Vedia, and De la Riva, 2004, Graellsia, 60: 169, provided records for Bolivia. Duellman, 2005, Cusco Amazonico: 266, provided an account (adult morphology, description of the call, life history). In the Pristimantis (Pristimantis) unistrigatus species group of Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 128. Bernarde, Machado, and Turci, 2011, Biota Neotrop., 11: 117–144, reported specimens from Reserva Extrativista Riozinho da Liberdade, Acre, Brazil (although identification requires confirmation). Not assignable to species group according to Padial, Grant, and Frost, 2014, Zootaxa, 3825: 127. See Duellman and Lehr, 2009, Terrest.-breeding Frogs in Peru: 138-139, for brief account. Ortega-Andrade, Rojas-Soto, Espinosa de los Monteros, Valencia, Read, and Ron, 2017, Herpetol. J., 26: 87–103, provided an extensive account and resurrected Pristimantis brevicrus from the synonymy of this species and noted two allied unnamed species in Bolivia and Brazil, usually referred to as Pristimantis altamazonicus. Araujo de Oliveira, Penhacek, Guimarães, Nascimento, Rodrigues, and Hernández-Ruz, 2019, MtDNA, Part A, 30: 731–738, discussed the species and its unnamed associates in Brazil. See brief account for the Manu region, Peru, by Villacampa-Ortega, Serrano-Rojas, and Whitworth, 2017, Amph. Manu Learning Cent.: 68–69. Metcalf, Marsh, Torres Pacaya, Graham, and Gunnels, 2020, Herpetol. Notes, 13: 753–767, reported the species from the Santa Cruz Forest Reserve, Loreto, northeastern Peru. Included in the Brazilian fauna by Segalla, Berneck, Canedo, Caramaschi, Cruz, Garcia, Grant, Haddad, Lourenço, Mângia, Mott, Nascimento, Toledo, Werneck, and Langone, 2021, Herpetol. Brasil., 10: 143, although this is presumably based on the associated cryptic species. Included in the Pristimantis diadematus clade of the Pristimantis unistrigatus group as delimited by Mônico, Koch, Ferrão, Fernandes, Marques, Chaparro, Rodrigues, Lima, and Fouquet, 2024, Mol. Phylogenet. Evol., 108203: 1–19, on molecular grounds (mtDNA and nuDNA genes) and noted at least three presumptively unnamed lineages associated under this name.
