Comment

See account by Cei, 1962, Batr. Chile: 111–115, and Cei, 1980, Monit. Zool. Ital., N.S., Monogr., 2: 213–215. Penna and Veloso, 1990, J. Herpetol., 24: 23–33, reported on advertisement call. See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 541. Bourke, Busse, and Bakker, 2011, Herpetol. J., 21: 227–234, reported on sex differences in dorsal pattern and body coloration. 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. Bourke, Busse, and Böhme, 2018, North-West. J. Zool., Romania, 14: 165–170, modeled the range and the expected effect of climate change. See Charrier, 2019, Anf. Bosques Centro Sur y Patagonia de Chile: 242–247, for account (morphology, habitat, natural history) and polygon distribution map. Serrano-Serrano, Penna, and Soto-Azat, 2020, Bioacoustics, 29: 522–589, reported on acoustics. Úbeda and Pastore, 2021, Bol. Chil. Herpetol., 8: 1–9, reported on the range, habitat, and conservation status in Argentina. Bidart-Enriquez, Serrano-Serrano, Penna, and Velásquez, 2025, Rev. Latinoam. Herpetol., 8: 177–133, suggested, on the basis of study of advertisement calls and morphology, that Rhinoderma rufum cannot adequately be distinguished from Rhinoderma darwini. But, they suggested that the nominal species species might be maintained pending genetic studies. DRF takes the conservative position here inasmuch as the conservation issues are severe if synonymy is made without genetic studies. They also suggested that the population from Isla Chiloe, Chile, is acoustically distinctive but may just represent the extreme of geographic variation within Rhinoderma darwini.
