Class: Amphibia > Order: Anura > Family: Phyllomedusidae > Genus: Agalychnis > Species: Agalychnis callidryas

Hyla callidryas Cope, 1862, Proc. Acad. Nat. Sci. Philadelphia, 14: 359. Holotype: ANSP 2091, according to Malnate, 1971, Proc. Acad. Nat. Sci. Philadelphia, 123: 349. Type locality: "Darien", Panama; corrected to Córdoba, Veracruz, Mexico, by Smith and Taylor, 1950, Univ. Kansas Sci. Bull., 33: 347; this correction considered unjustified by Dunn and Stuart, 1951, Copeia, 1951: 57, and Duellman, 1970, Monogr. Mus. Nat. Hist. Univ. Kansas: 102.

Red-eyed Multicolored Treefrog (Hedges, Powell, Henderson, Hanson, and Murphy, 2019, Caribb. Herpetol., 67: 13).


Northeastern Honduras and eastern Nicaragua southeastward on the Caribbean lowlands to central Panama; Pacific lowlands of southern Costa Rica and eastern Panama to the Chocó of Colombia, sea level to 1325 m elevation. See comment. 


Intraspecific variation (in the sense of including Agalychnis taylori) discussed by Savage and Heyer, 1967, Beitr. Neotrop. Fauna, 5: 111–131, analyzed intraspecific variation. See account by Duellman, 1970, Monogr. Mus. Nat. Hist. Univ. Kansas: 102–112, and note by Duellman, 2001, Hylid Frogs Middle Am., Ed. 2: 839–840. Lips and Savage, 1996, Proc. Biol. Soc. Washington, 109: 17–26, included this species in a key to the tadpoles found in Costa Rica. See also accounts by Lee, 1996, Amph. Rept. Yucatan Peninsula: 84–86; Campbell, 1998, Amph. Rept. N. Guatemala Yucatan Belize: 73–75, and Lee, 2000, Field Guide Amph. Rept. Maya World: 89-92. See accounts by Savage, 2002, Amph. Rept. Costa Rica: 281–283, and McCranie and Wilson, 2002, Amph. Honduras: 231–236. McCranie, 2007, Herpetol. Rev., 38: 37, detailed the departmental distribution in Honduras. Robertson, Duryea, and Zamudio, 2009, Mol. Ecol., 18: 1375–1395, discussed phylogeographic patterns in Costa Rica. See comments by Sunyer, Páiz, Dehling, and Köhler, 2009, Herpetol. Notes, 2: 189–202, regarding Nicaraguan populations. In the Agalychis callidryas group of Faivovich, Haddad, Baêta, Jungfer, Álvares, Brandão, Sheil, Barrientos, Barrio-Amorós, Cruz, and Wheeler, 2010, Cladistics, 26: 259. Previous records from the Magdalena River Valley of Colombia are now referred to Agalychnis terranova; see Rivera-Correa, Duarte-Cubides, Rueda-Almonacid, and Daza-R., 2013, Zootaxa, 3636: 85–100. Köhler, 2011, Amph. Cent. Am.: 198–201, provided a key to the species of Central America and provided a map and photograph of the species, including this one.. Sunyer, Martínez-Fonseca, Salazar-Saavedra, Galindo-Uribe, and Obando, 2014, Mesoam. Herpetol., 1: 168, provided records for the departments of Carozo and Estelí, Nicaragua. McCranie, Sunyer, and Martínez-Fonseca, 2019, Rev. Nicaraguense Biodiversidad, 52: 8–9, partitioned the nominal species, recognizing Agalychnis taylori and suggested that populations from eastern Honduras and northern Costa Rica might be a distinct species, for which the name Agalychnis helenae is available, but did not take the taxonomic action. Therefore literature from 1967 to 2019 for Agalychis callidryas must be used with caution.
