In the Hyla eximia group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 102; this confirmed by  Li, Wang, Nian, Litvinchuk, Wang, Li, Rao, and Klaus, 2015, Mol. Phylogenet. Evol., 87: 80–90, who also provided evidence for cryptic species within this complex. For discussion see Duellman, 1970, Monogr. Mus. Nat. Hist. Univ. Kansas: 499–505 (in the sense of including Hyla wrightorum), and Duellman, 2001, Hylid Frogs Middle Am., Ed. 2: 985–987. See comments under Hyla wrightorum. Painter, 1986, Herpetol. Rev., 17: 26, provided the first record for Colima. Uribe-Peña, Ramírez-Bautista, and Casas-Andreu, 1999, Cuad. Inst. Biol., UNAM, 32: 29–32, provided an account. Eliosa León, 2002, Bol. Soc. Herpetol. Mexicana, 10: 59–60, reported on geographic variation; see comments under Hyla arboricola and Hyla wrightorum. Reyes-Velasco, Hermosillo-López, Grünwald, and Avila-López, 2009, Herpetol. Rev., 40: 117–120, provided a record for Colima, Mexico. Korky and Webb, 1991, Bull. New Jersey Acad.
