Hylodes henselii Peters, 1870, Monatsber. Preuss. Akad. Wiss. Berlin, 1870: 648. Holotype: ZMB 6813, stated in the original publication and located by Kwet and Solé, 2005, J. Herpetol., 39: 530; NHMW 16515 designated neotype in error by Heyer, 1984, Smithson. Contrib. Zool., 402: 27, who regarded the type as lost, as previously did Lynch, 1976, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 61: 7. Type locality: Not stated in original publication other than being Brazilian, but in the description indicated by Peters (Hensel, 1867, Arch. Naturgesch., 33: 161) the type locality is given as "Porto Alegre", Rio Grande do Sul, Brazil.

English Names

None noted.


Subtropical Atlantic rainforest and parts of the Araucaria forest in southern Brazil and Misiones, Argentina; likely into adjacent Paraguay.

Geographic Occurrence

Natural Resident: Argentina, Brazil

Likely/Controversially Present: Paraguay


Removed from the synonymy of Eleutherodactylus guentheri by Kwet and Solé, 2005, J. Herpetol., 39: 522, where it had been placed by Heyer, 1984, Smithson. Contrib. Zool., 402: 27. Argentine record (as Eleutherodactylus guentheri) by Carrizo, De Olmedo, and Soroka, 1989, Bol. Asoc. Herpetol. Argentina, 5: 10–11. Brusquetti and Lavilla, 2006, Cuad. Herpetol., 20: 27, suggested that this species likely occurs in Paraguay. In the Ischnocnema guentheri species series of Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 27, Canedo and Haddad, 2012, Mol. Phylogenet.

Monogr., 32: 17, and Taucce, Canedo, Parreiras, Drummond, Nogueira-Costa, and Haddad, 2018, Mol. Phylogenet.

Genetics, 14: 973–982, reported on phylogenetic placement within the Ischnocnema guentheri series. Rodriguez, Börner, Pabijan, Gehara, Haddad, and Vences, 2015, Evol. Ecol., 29: 765–785 (and supplemental data), reported on phylogeographic diversity and its causes. Lucas, Bastiani, and Lingnau, 2018, Rev. Brasil.
