In the Hyla eximia group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 102. See Duellman, 1970, Monogr. Mus. Nat. Hist. Univ. Kansas: 510–513. 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: 248. Hua, Fu, Li, Nieto-Montes de Oca, and Wiens, 2009, Herpetologica, 65: 246–259, placed Hyla walkeri in the Hyla eximia group and suggested that the specimen sequenced by Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294, was misidentified, being a member of the Hyla japonica group. Köhler, 2011, Amph. Cent. Am.: 229–230, provided a brief summary of natural history for the species of Hyla in Central America and provided a range map and photograph for this species.
