Comment

In the Eleutherodactylus guentheri cluster, according to the original publication. In the Eleutherodactylus (Eleutherodactylus) binotatus series, Eleutherodactylus binotatus group of Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 226. Guerra Batista, Llusia, Gambale, Morais, Márquez, and Bastos, 2018, PLoS One, 13(1: e0191691): 1–22 and Table S1, reviewed the literature of advertisement calls. Canelas and Bertoluci, 2007, Iheringia, Zool., 97: 21–26, provided a second locality. In the Ischnocnema guentheri species series of Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 27, Canedo and Haddad, 2012, Mol. Phylogenet. Evol., 65: 619, Padial, Grant, and Frost, 2014, Zootaxa, 3825: 122, Taucce, Canedo, Parreiras, Drummond, Nogueira-Costa, and Haddad, 2018, Mol. Phylogenet. Evol., 128: 123–146. Taucce, Leite, Santos, Feio, and Garcia, 2012, Pap. Avulsos Zool., São Paulo, 52: 111–119, reported on the range, color pattern variation, and advertisement call. Coletta and Vasconcelos, 2025, Austral Ecol., 5-(8: e70112): 1–11, discussed the affects of climate change on potential distribution. Fontana, Brum, Both, and Hartz , 2025, Biodivers.
