Comment

See accounts by Duellman, 1970, Monogr. Mus. Nat. Hist. Univ. Kansas: 284–289, and Savage and Heyer, 1969, Rev. Biol. Tropical, 16: 1–127. Lips and Savage, 1996, Proc. Biol. Soc. Washington, 109: 17–26, included this species (as Hyla rivularis) in a key to the tadpoles found in Costa Rica. Duellman, 2001, Hylid Frogs Middle Am., Ed. 2: 876, transferred former members of the Hyla rivularis group into the Hyla pictipes group. See account by Savage, 2002, Amph. Rept. Costa Rica: 323–324. In the Isthmohyla pictipes group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 103. Urbina-Cardona and Loyola, 2008, Tropical Conserv. Sci., 1: 417–445, modeled the distribution. See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 255. Köhler, 2011, Amph. Cent. Am.: 236–244, provided a brief summary of natural history for the species of Isthmohyla in Central America and provided a range map and photograph for this species. Jiménez, Ballestero, Astorga, Rodríguez, and Alvarado, 2019, Herpetol. Rev., 50: 322, provided a record forJuan Castro Blanco National Park, Alajuela Province, Costa Rica.
