Comment

In the Scinax perpusillus group according to Peixoto, 1989 "1988", Arq. Univ. Fed. Rural Rio de Janeiro, 11: 27–37, who noted this name covers a complex of species. Pombal, Bastos, and Haddad, 1995, Naturalia, São Paulo, 20: 213–225, reported on the advertisement call. In the Scinax catharinae clade, Scinax perpusillus group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 96. See account by Heyer, Rand, Cruz, Peixoto, and Nelson, 1990, Arq. Zool., São Paulo, 31: 281–282. Izecksohn and Carvalho-e-Silva, 2001, Anf. Municipio Rio de Janeiro: 59, provided a brief account and photo. Alves-Silva and Silva, 2010 "2009", J. Nat. Hist., London, 43: 205–217, discussed vocalization. Bell, Brasileiro, Haddad, and Zamudio, 2012, J. Biogeograph., 39: 1733–1742, reported on molecular phylogenetics of this and closely related species. Muscat, Augusto-Alves, Toledo, Tanaka, and Stuginski, 2019, Herpetol. Notes, 12: 1067–1072, reported on amplectant and advertisement calls and larval development.
