Class: Amphibia > Order: Anura > Family: Hylidae > Subfamily: Hylinae > Genus: Dendropsophus > Species: Dendropsophus brevifrons

Hyla brevifrons Duellman and Crump, 1974, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 23: 15. Holotype: KU 126370, by original designation. Type locality: "Santa Cecilia, Provincia Napo, Ecuador".

Dendropsophus brevifrons — Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 93.

English Names

Crump Treefrog (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 54).

Distribution

Upper Amazon Basin of Colombia, Ecuador, and Peru, as well as Amazonas, Acre, and Rondônia, Brazil; possibly into Amazonian Bolivia.

Geographic Occurrence

Natural Resident: Brazil, Colombia, Ecuador, Peru

Likely/Controversially Present: Guyana

Comment

In the Dendropsophus parviceps group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 93. In the Hyla parviceps group according to the original publication and Duellman, 2001, Hylid Frogs Middle Am., Ed. 2: 859. Duellman, 1978, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 65: 135–136, provided a brief account including characterization of call and tadpole. Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 25–26, provided a brief account as Hyla brevifrons. 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. Duellman, 2005, Cusco Amazonico: 202–204, provided an account (adult and larval morphology, description of the call, life history). Lynch, 2006, Caldasia, 28: 140, characterized the range in Colombia. Ernst, Rödel, and Arjoon, 2005, Salamandra, 41: 179-194, provided a record for central Guyana and noted records in Amazonas, Brazil (this likely now referrable to Dendropsophus counani; requiring genetic confirmation). See comments under Dendropsophus counani, which was previously confused with this species. Fouquet, Gilles, Vences, Marty, Blanc, and Gemmell, 2007, PLoS One, 10 (e1109): 1–10, provided molecular evidence that this is a species complex. Bernarde, Machado, and Turci, 2011, Biota Neotrop., 11: 117–144, reported specimens from Reserva Extrativista Riozinho da Liberdade, Acre, Brazil. Lynch and Suárez-Mayorga, 2011, Caldasia, 33: 235–270, illustrated the tadpole and included the species in a key to the tadpoles of Amazonian Colombia. Motta, Menin, Almeida, and Hrbek, 2018, Zootaxa, 4438: 79–104, on the basis of 16S rRNA sequence divergence suggested that this nominal species is composed of at least two cryptic species. For identification of larvae (as Hyla cf. brevifrons) in central Amazonia, Brazil, see Hero, 1990, Amazoniana, 11: 201–262. 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. In the Dendropsophus parviceps group of Orrico, Grant, Faivovich, Rivera-Correa, Rada, Lyra, Cassini, Valdujo, Schargel, Machado, Wheeler, Barrio-Amorós, Loebmann, Moravec, Zina, Solé, Sturaro, Peloso, Suárez, and Haddad, 2021, Cladistics, 37: 73–105. Taucce, Costa-Campos, Carvalho, and Michalski, 2022, Eur. J. Taxon., 836: 112, noted that records of Dendropsophus brevifrons from Amapá, Brazil (published by Benício and Lima, 2017, Herpetol. Notes, 10) are referrable to Dendropsophus counani. Schiesari, Rossa-Feres, Menin, and Hödl, 2022, Zootaxa, 5223: 50–51, detailed (as Dendropsophus cf. brevifrons) larval morphology and natural history.. Lescure, Dewynter, Frétey, Ineich, Ohler, Vidal, and De Massary, 2022, Bull. Soc. Herpetol. France, 181(5): 1–17, transferred records from French Guiana to Dendropsophus counani. Crnobrna, Santa-Cruz Farfan, Gallegos, López-Rojas, Llanqui, Panduro Pisco, and Kelsen Arbaiza, 2023, Check List, 19: 443, provided a record from Ucayali Department, central-eastern Peru.
