In the Scinax ruber group according to the original publication. The Scinax ruber group rejected as nonmonophyletic by Faivovich, 2002, Cladistics, 18: 367-393.

Peruvanian records from Duellman and Salas, 1991, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 143: 4. See account by Duellman and Wiens, 1993, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 153: 3-8. See De la Riva, Márquez, and Bosch, 1994, Bijdr. Dierkd., 64: 75–85, for advertisement call. De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 36, suggested that Peruvian populations may not be conspecific with the Bolivian populations. Duellman, 2005, Cusco Amazonico: 237–238, provided an account (adult morphology, description of the call, life history). In the Scinax funereus 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.
