Comment

Basso, 1997, in Rocek and Hart (eds.), Abstr. 3rd World Congress Herpetol.: 13, discussed phylogenetic relationships among the species and suggested that Atelognathus granidsonae might be the sister-taxon of Somuncuria + other Atelognathus. Evidence from the original paper naming Chaltenobatrachus suggested that this species is the sister of Atelognathus. Díaz-Páez, Alveal, Cisternas-Medina, and Ortiz, 2015, Check List, 11: 1–3, provided records from Chilean Patagonia and discussed the range.
