English Names

Tiny Tree Toad (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 44).

Amazonian Tiny Tree Toad (De la Riva, 1999, Herpetozoa, Wien, 12: 91).


Amazonian Venezuela (Amazonas), Colombia (from the llanos of Meta south to Amazonia), Brazil adjacent to Amazonian Venezuela and Colombia. Older records from other countries now apply to other species. 


Discussed by Duellman, 1978, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 65: 120-121, who reported geographic variation in belly pattern. D.C. Cannatella and M.S. Hoogmoed in Hoogmoed, 1985, In Frost (ed.), Amph. Species World: 67, believed that this variation is due to two species being confounded. Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 12, provided a brief account, as Dendrophryniscus minutus.  De la Riva, 1999, Herpetozoa, Wien, 12: 91-92, reported the Bolivian record. Lescure and Marty, 2000, Collect. Patrimoines Nat., Paris, 45: 56-57, provided a brief account, including a call description, and photo. Lynch, 2006, Caldasia, 28: 138, characterized the range in Colombia. See account (as Dendrophryniscus minutus) for Surinam population by Ouboter and Jairam, 2012, Amph. Suriname: 52-53. Rojas-Runjaic, Castroviejo-Fisher, and Barrio-Amorós, 2013, Check List, 9: 1122-1123, provided a record from northwestern Amazonas, Venezuela. Rojas-Zamora, Carvalho, Gordo, Ávila, and Farias, 2014, Zootaxa, 3753: 79-95, suggested that unnamed species currently under this name exist in western Amazonia and on the Guiana Shield, and transferred record from the Manaus region of Amazonia to Amazophrynella manaos. With the naming of Amazophrynella matses, Amazophrynella javierbustamantei, and Amazophrynella amazonicola from Peru and the recognition of a likely unnamed species from western Amazonia by Rojas-Zamora, Carvalho, Ávila, Farias, Gordo, and Hrbek, 2015, Zootaxa, 3946: 79–103, it is not clear that non-topotypic populations of Amazophrynella minuta can confidently be assigned to that species (DRF). See map by Rojas-Zamora, Fouquet, Ron, Hernández-Ruz, Melo-Sampaio, Chaparro, Vogt, Carvalho, Pinheiro, Ávila, Farias, Gordo, and Hrbek, 2018, PeerJ, 6(e4941): 7, who discussed evolution within the genus and redelimited this species with the result that all previous literature of this species should be used with caution. Duellman, 1978, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 65: 1–352, reported on nominal Dendrophryiscus minutus, including the call, from Cuzco Amazonica, Ecuador, but the taxonomic identity of this population is now in doubt.
