Comment

See Duellman, 1974, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 27: 19. Many color morphs of this species have been recognized taxonomically (W. E. Duellman in Frost, 1985, Amph. Species World: 155). Considered by Cope, 1870 "1869", Proc. Am. Philos. Soc., 11: 156, and Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 387, to be a junior synonym of Hyla leucophyllata. See comments by Heyer, 1977, Pap. Avulsos Zool., São Paulo, 31: 144 Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 38, provided a brief account for the Iquitos region of northeastern Peru as Hyla triangulum. In the Dendropsophus leucophyllatus group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 91.Caminer, Milá, Jansen, Fouquet, Venegas, Chávez, Lougheed, and Ron, 2017, PLoS One, 12(3: e0171785): 1–42, revised the group, provided a detailed account, phylogenetic placement, and redelimited the species.
