English Names

Amazonian Poison Frog (Walls, 1994, Jewels of the Rainforest: 24; Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 50).

Distribution

Amazon drainage of Colombia (vicinity of Leticia), Ecuador, Peru, and presumably into adjacent far western Amazonas, Brazil, from the foothills of the Andes east.

Comment

Caldwell and Myers, 1990, Am. Mus. Novit., 2988: 1-21, removed this species from the synonym of Ranitomeya quinquevittata (as Dendrobates), where it had been placed by Silverstone, 1975, Sci. Bull. Nat. Hist. Mus. Los Angeles Co., 21: 33. Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 17, provided a brief account as Dendrobates ventrimaculatus. Lescure and Marty, 2000, Collect. Patrimoines Nat., Paris, 45: 92–93, provided a brief account and photo. Symula, Schulte, and Summers, 2001, Proc. R. Soc. London, Ser. B, Biol. Sci., 268: 2415–2421, suggested that Ranitomeya ventrimaculata is composed of two cryptic species, one of which is more closely related to Ranitomeya variabilis. Schulte, 1999, Pfeilgiftfrösche: 129-134 (Dendrobates ventrimaculatus), 470–471 (Dendrobates duellmani), provided an account. Fouquet, Gilles, Vences, Marty, Blanc, and Gemmell, 2007, PLoS One, 10 (e1109): 1–10, provided molecular evidence that this is a species complex. Lötters, Jungfer, Henkel, and Schmidt, 2007, Poison Frogs: 504-511, provided an account and placed this species in their Ranitomeya ventrimaculata group. Twomey and Brown, 2009, Zootaxa, 2302: 54, discussed the advertisement call. In the Ranitomeya reticulata species group of Brown, Twomey, Amézquita, Souza, Caldwell, Lötters, von May, Melo-Sampaio, Mejía-Vargas, Pérez-Peña, Pepper, Poelman, Sanchez-Rodriguez, and Summers, 2011, Zootaxa, 3083: 47, and who provided an account on page 59–61, redelimited the species (mapped), and transferred records from French Guiana to Ranitomeya amazonica. Estupiñán, Ferrari, Gonçalves, Barbosa, Vallinoto, and Schneider, 2016, ZooKeys, 637: 89–106, suggested on the basis of COI barcodes that cryptic species are likely. 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.
