For discussion see Duellman, 1970, Monogr. Mus. Nat. Hist. Univ. Kansas: 188–193, and Savage and Heyer, 1969, Rev. Biol. Tropical, 16: 1–127. In the Scinax ruber clade, unassigned to group, of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 97. The species name is a noun in apposition and does not change endings in combination with a masculine generic name. Lips and Savage, 1996, Proc. Biol. Soc. Washington, 109: 17–26, included this species (as Hyla elaeochroa) in a key to the tadpoles found in Costa Rica. See account by Savage, 2002, Amph. Rept. Costa Rica: 345–347. See comments by Sunyer, Páiz, Dehling, and Köhler, 2009, Herpetol. Notes, 2: 189–202, regarding Nicaraguan populations. Köhler, 2011, Amph. Cent. Am.: 262–264, provided a brief summary of natural history and identification key for the species of Scinax in Central America and provided a range map and photograph for this species. See discussion and revision by Ron, Duellman, Caminer, and Pazmiño, 2018, PLoS One, 13 (9: e0203169): 1–26, who discussed the systematics, call, and noted that records of Scinax elaeochroa from Nariño province, Colombia, most likely represent Scinax tsachila and that records to the north of there from western Colombia most likely refer to Scinax quinquefasciatus, Scinax tsachila, Scinax caprarius, or an unnamed member of the genus. In the Scinax elaeochroa group of Araujo-Vieira, Lourenço, Lacerda, Lyra, Blotto, Ron, Baldo, Pereyra, Suárez-Mayorga, Baêta, Ferreira, Barrio-Amorós, Borteiro, Brandão, Brasileiro, Donnelly, Dubeux, Köhler, Kolenc, Leite, Maciel, Nunes, Orrico, Peloso, Pezzuti, Reichle, Rojas-Runjaic, Silva, Sturaro, Langone, Garcia, Rodrigues, Frost, Wheeler, Grant, Pombal, Haddad, and Faivovich, 2023, S. Am. J. Herpetol., 27 (Special Issue): 94 (see comment under Hylinae). Martínez-Fonseca, Holmes, Sunyer, Westeen, Grundler, Cerda, Fernández-Mena, Loza-Molina, Monagan, Nondorf, Pandelis, and Rabosky, 2024, Check List, 20: 71, provided and discussed a record from Refugio Bartola, Departamento Río San Juan, Nicaragua.
