 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 altamazonicusAraujo 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.
