Comment

See account (as Melanophryniscus dorsalis) by Cruz and Caramaschi, 2003, Bol. Mus. Nac., Rio de Janeiro, N.S., Zool., 500: 1-5, who considered it a species distinct from Melanophryniscus stelzneri and in the Melanophryniscus stelzneri group. See photograph, map, description (as Melanophryniscus dorsalis) of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 195. Kwet, Maneyro, Zillikens, and Mebs, 2005, Salamandra, 41: 1–8, reported on the call. Zank, Becker, Abadie, Baldo, and Maneyro, 2014, PLoS One, E 9(4: e94625): 1–11, provided (as Melanophryniscus dorsalis) modeled distribution maps for the species under climate change. Moser, Farina, Borges-Martins, Machado, Colombo, and Tozetti, 2021, Neotrop. Biol. Conserv., 16: 443, noted that earlier records of Melanophryniscus atroluteus from the municipality of São Leopoldo, Rio Grande do Sul, Brazil, actually apply to this species. Freire, Regnet, Machado, Loebmann, and Verrastro, 2022, Zootaxa, 5129: 442–446, reported on larval morphology. Langone and Lavilla, 2024, Comun. Zool. Mus. Hist. Nat. Montevideo, 13: 14–16, discussed the taxonomic literature including misidentifications.
