Comment

In the Scinax catharinae group according to Duellman and Wiens, 1992, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 151: 23, but considered to be in the Scinax rizibilis group by Haddad and Pombal, 1987, Rev. Brasil. Biol., 47: 127–132. Subsequently the Scinax rizibilis group was combined into the Scinax catharinae group by Pombal, Bastos, and Haddad, 1995, Naturalia, São Paulo, 20: 213–225. In the Scinax catharinae clade, Scinax catharinae group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 95–96. See account by Heyer, Rand, Cruz, Peixoto, and Nelson, 1990, Arq. Zool., São Paulo, 31: 279–281. Tadpoles compared to those of other members of the Scinax catharinae group by Conte, Nomura, Rossa-Feres, d'Heursel, and Haddad, 2007, Amphibia-Reptilia, 28: 177–192.
