Comment

In the Eleutherodactylus (Eleutherodactylus) binotatus series, Eleutherodactylus lacteus group of Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 226. In the Ischnocnema lactea species series of Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 27,  Canedo and Haddad, 2012, Mol. Phylogenet. Evol., 65: 619, and Padial, Grant, and Frost, 2014, Zootaxa, 3825: 122, and Taucce, Canedo, Parreiras, Drummond, Nogueira-Costa, and Haddad, 2018, Mol. Phylogenet. Evol., 128: 123–146. Nogueira da Costa, Carvalho-e-Silva, and Carvalho-e-Silva, 2008, Check List, 4: 232–233, provided the record for the Serra dos Órgaos, São Paulo, Brazil. Targino and Carvalho-e-Silva, 2008, Rev. Brasil. Zool., 25: 716–723, redescribed the species from topotypes. Thomé, Lyra, Lemes, Teixeira, Carnaval, Haddad, and Canedo, 2020, Mol. Phylogenet. Evol., 149 (106813): 1–13, discussed the molecular phylogenetics of the Ischnocnema lactea/Ischnocnema holti complex, suggesting that seven lineages are involved, of which only the lineages at the type localities bear the current names. Nevertheless, the authors hesitated to make any taxonomic recommendations.
