Comment

In the Eleutherodactylus guentheri cluster of Heyer, 1984, Smithson. Contrib. Zool., 402: 42, who described the call. See account by Heyer, Rand, Cruz, Peixoto, and Nelson, 1990, Arq. Zool., São Paulo, 31: 296-297, which included a description of the call. In the Eleutherodactylus (Eleutherodactylus) binotatus series, Eleutherodactylus binotatus group of Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 225. Izecksohn and Carvalho-e-Silva, 2001, Anf. Municipio Rio de Janeiro: 83, provided a brief account and photo (at the time including Eleutherodactylus henselii as a synonym). Siqueira, Ananias, and Recco-Pimentel, 2004, Genet. Mol. Biol., 27: 363-372, compared the karyotypes of Eleutherodactylus binotatus, Eleutherodactylus guentheri, and Eleutherodactylus parvus. Kwet and Solé, 2005, J. Herpetol., 39: 521-532, revised this taxon, showing Eleutherodactylus henselii to be a distinct species, and noted another unnamed species within nominal Eleutherodactylus guentheri from Boraceia, São Paulo, Brazil. 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, and Taucce, Canedo, Parreiras, Drummond, Nogueira-Costa, and Haddad, 2018, Mol. Phylogenet. Evol., 128: 123–146 (who noted several unnamed species under this name). Cruz, Feio, and Caramaschi, 2009, Anf. Ibitipoca: 52-53, provided photographs and a brief account for Parque Estadual do Ibitipoca, Minas Gerais, Brazil. Pombal, 2010, Arq. Mus. Nac., Rio de Janeiro, 68: 135 144, reported on the call. Gehara, Canedo, Haddad, and Vences, 2013, Conserv. Genetics, 14: 973–982, restricted the name Ischnocnema guentheri to one population within the city of Rio de Janeiro, Brazil, and noted that other populations formerly associated with this name in Santa Catarina, Paraná, São Paulo, Rio de Janeiro, and Minas Gerais, Brazil, actually represent four unnamed species. Rodriguez, Börner, Pabijan, Gehara, Haddad, and Vences, 2015, Evol. Ecol., 29: 765–785 (and supplemental data), reported on phylogeographic diversity and its causes. Taucce, Canedo, and Haddad, 2018, Herpetol. Monogr., 32: 5, provided a molecular tree of Ischnocnema which suggested that this nominal species is composed of several cryptic species, some more closely related to Ischnocnema henselii than to other populations of Ischnocnema guentheri. Taucce, Canedo, Haddad, Lemmon, Lemmon, Vences, and Lyra, 2018, MtDNA, Part B, 3: 915–917, reported on the mtDNA genome.
