Geographic Occurrence

Natural Resident: Brazil, Uruguay


In the Melanophryniscus stelzneri group of Cruz and Caramaschi, 2003, Bol. Mus. Nac., Rio de Janeiro, N.S., Zool., 500: 1-11. See comment under Melanophryniscus atroluteus. Tedros, Kolenc, and Borteiro, 2001, Cuad. Herpetol., 15: 143, provided the Brazilian record. Langone, 1995 "1994", Mus. Damaso Antonio Larrañaga, Ser. Divulg. 5: 30-31, and Achaval and Olmos, 2003, Anf. Rept. Uruguay, ed. 2: 16, provided for the Uruguayan population a brief account. Maneyro and Kwet, 2008, Stuttgart. Beit. Naturkd., Ser. A, Neue Ser., 1: 95-121, provided comments on range and conservation status. 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: 196. Baldo in Vaira, Akmentins, Attademo, Baldo, Barrasso, Barrionuevo, Basso, Blotto, Cairo, Cajade, Céspedez, Corbalán, Chilote, Duré, Falcione, Ferraro, Gutierrez, Ingaramo, Junges, Lajmanovích, Lescano, Marangoni, Martinazzo, Marti, Moreno, Natale, Pérez Iglesias, Peltzer, Quiroga, Rosset, Sanabria, Sanchez, Schaefer, Úbeda, and Zaracho, 2012, Cuad. Herpetol., 26 (Supl. 1): 134, suggested that unnamed populations to the south of Buenos Aires, Argentina, may be referable to this species, although these have subsequently been named as Melanophryniscus diabolicus and Melanophryniscus nigricans. Agnolin and Guerrero, 2017, Check List, 13(4): 11–15, reported on local extinction in the eastern part of Buenos Aires Province, Argentina. Kwet, Maneyro, Zillikens, and Mebs, 2005, Salamandra, 41: 1–18, reported on the call. Zank, Becker, Abadie, Baldo, and Maneyro, 2014, PLoS One, E 9(4: e94625): 1–11, provided modeled distribution maps for the species under climate change. Maneyro, Langone, and Carreira, 2019, in Maneyro, Langone, and Carreira (eds.), Libro Rojo Anf. Rept. Uruguay: 23–28, provided an account for Uruguay and discussed the putative populations in Buenos Aires Province, Argentina, now presumably associated with Melanophryniscus nigricans and/or Melanophryniscus diabolicus.
