English Names

None noted.


Central Bolivia north to western Amazonian Brazil (as well as likely into eastern Peru, extreme southeastern Colombia, extreme southern Venezuela, and Guyana) to Suriname, French Guiana, Amapá and northern Pará, Brazil. 


Care should be employed in using literature prior to 2021 due to widespread confusion with Dendopsophus nanus and with named and unnamed species found from eastern Bolivia to throughout eastern Brazil. Zimmerman, 1983, Herpetologica, 39: 235–246, reported on advertisement call (as Hyla nana; here presumed to apply to Dendropsophus walfordi on the basis of range). Removed from the synonymy of Hyla nana by Langone and Basso, 1987, Comun. Zool. Mus. Hist. Nat. Montevideo, 11: 1-17 (who noted that it might be in the Hyla microcephala group), and De la Riva, Márquez, and Bosch, 1997, Bonn. Zool. Beitr., 47: 175–185 (who described the call), where it had been placed by Lutz, 1973, Brazil. Spec. Hyla: 223. For identification of larvae (as Hyla nana, presumed here to be Dendropsophus walfordi) in central Amazonia, Brazil, see Hero, 1990, Amazoniana, 11: 201–262. See account for Suriname population by Ouboter and Jairam, 2012, Amph. Suriname: 126–127 (as Dendropsophus nanus). Lescure and Marty, 2000, Collect. Patrimoines Nat., Paris, 45: 154–155, provided a photo and brief account for French Guiana (as Hyla nana). Márquez, De la Riva, and Bosch, 1993, Biotropica, 25: 426–443, described the advertisement call (as Hyla nana) and because of this De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 57, consider this species possibly to occur in Bolivia, although Köhler, 2000, Bonn. Zool. Monogr., 48: 60, noted that the record for Bolivia was based on a specimen of Hyla tritaeniata. In the Dendropsophus microcephalus group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 91-92. In the Dendropsophus microcephalus 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. Seger, Teixeira, Annibale, Rossa-Feres, Lima, Andrade, Giaretta, and Lourenço, 2021, Diversity, 13 (11: 522): 1–23, refined the taxonomic status of this species as well as that of Dendropsophus nanus, noting three unnamed lineages in eastern Brazil, eastern Bolivia, and south-central Brazil. Taucce, Costa-Campos, Carvalho, and Michalski, 2022, Eur. J. Taxon., 836: 96–130, reported on distribution, literature, and conservation status for Amapá, Brazil.
