English Names

None noted.


Known from the type locality in subtropical montane forest at the type locality (Los Toldos, Departamento Santa Victoria) and about 70 km to the south to near Isla de Cañas (Departamento Iruya), both in the Provincia Salta, Río Piedras and Aguas Blancas, both in the Departamento Oran, and from El Duraznito, Departamento General Manuel Belgrano, Provincia de Jujuy, and from Ciudad de Las Lomitas, Departamento Patiño, Provincia de Formosa, Argentina; likely extends into adjacent southern Bolivia.


External morphology, morphometrics, osteology, advertisement call, and natural history were detailed in the original publication. Cajade, Barrasso, and Nenda, 2009, Check List, 5: 418–421, provided the second record in Argentina and agreed with E. Lavilla (IUCN Red List online) that at least some populations of spotted-bellied frogs current identified as Elachistocleis ovalis in southern Bolivia may apply to this species. Pereyra and Akmentins, 2011, Cuad. Herpetol., 25: 59–60, provided the first record for Jujuy Province, Argentina,  Schaefer, Kehr, and Duré, 2012, Cuad. Herpetol., 26: 49–53, provided the record for Formosa, Argentina, and discussed the known range. Jowers, Othman, Borzée, Rivas-Fuenmayor, Sánchez-Ramírez, Auguste, Downie, Read, and Murphy, 2021, Organisms Divers. Evol., 21: 189–206, discussed the phylogenetics and biogeography of this species.
