Comment

In the Melanophryniscus tumifrons group of Cruz and Caramaschi, 2003, Bol. Mus. Nac., Rio de Janeiro, N.S., Zool., 500: 1-11. See Braun, 1973, Iheringia, Zool., 44: 3-13, for discussion. Baldo and Krauczuk, 1999, Cuad. Herpetol., 13: 101, provided the record for Argentina. Langone, 1995 "1994", Mus. Damaso Antonio Larrañaga, Ser. Divulg. 5: 34-35, and Achaval and Olmos, 2003, Anf. Rept. Uruguay, ed. 2: 15, provided for the Uruguayan population a brief account. Zanella, Busin, Giusti, Leonardo, and Oliveira, 2007, Check List, 3: 104, provided the first record for Brazil. Brusquetti and Lavilla, 2006, Cuad. Herpetol., 20: 27, suggested that this species likely occurs in adjacent Paraguay. Maneyro and Kwet, 2008, Stuttgart. Beit. Naturkd., Ser. A, Neue Ser., 1: 95-121, suggested that the Argentinian population might represent an unnamed species. 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: 195. Airaldi, Baldo, and Lavilla, 2009, Check List, 5: 377-379, provided the first record for Paraguay and provided a range map for the species. Boeris, Ferro, Krauczuk, and Baldo, 2010, Check List, 6: 395-396, provided a record for Corrientes Province, Argentina. Núñez, 2011, Herpetol. Rev., 42: 107, provided a record for Itapúa Department, Paraguay. Weiler, Núñez, Airaldi, Lavilla, Peris, and Baldo, 2013, Anf. Paraguay: 33, provided a brief account, image, and dot map for Paraguay. 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. See account by Maneyro, Langone, and Carreira, 2019, in Maneyro, Langone, and Carreira (eds.), Libro Rojo Anf. Rept. Uruguay: 35–39, for Uruguay.
