Comment

See account (as Telmatobius nitoi) by Cei, 1980, Monit. Zool. Ital., N.S., Monogr., 2: 243–244. Díaz-Páez, Vidal-Maldonado, Ortiz, Úbeda, and Basso, 2011, Zootaxa, 2880: 20–30, discussed the systematics and range of nominal Atelognathus salai. See photograph, map, description of geographic range and habitat, and conservation status of nominal Atelognathus salai in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 296. Scolaro, Martinazzo, and Basso, 2008, Herpetol. Rev., 39: 232–233, provided the southernmost record (as Atelognathus jeinimenensis), from Paso Roballos, Santa Cruz province, Argentina. See statement of geographic range, habitat, and conservation status (as Atelognathus nitoi and Atelognathus jeinimenensis) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 618. See Lobos, Vidal-Maldonado, Correa-Quezada, Labra-Lillo, Díaz-Páez, Charrier, Rabanal, Díaz-Vidal, and Tala, 2013, Anf. Chile Conserv. 1–104, for photograph, comments on conservation status, and range (as Atelognathus salai and Atelognathus ceii). See Raimilla, 2015, Bol. Chil. Herpetol., 2: 22–23, for a new locality and discussion of the range (as Atelognathus salai). Barrasso and Basso, 2019, J. Zool. Syst. Evol. Res., 57: 383–399, revised the species based on morphology and DNA evidence. Figueroa-Ponce and Moya, 2023, Bol. Mus. Nac. Hist. Nat., Santiago, 72: 13–19, reported on the distribution, detailing all historic and new localities, and commented on its conservation status.
