Comment

In the Melanophryniscus stelzneri group of Cruz and Caramaschi, 2003, Bol. Mus. Nac., Rio de Janeiro, N.S., Zool., 500: 1-11. Removed from the synonymy of Melanophryniscus stelzneri by Klappenbach and Langone, 1992, An. Mus. Nac. Hist. Nat. Montevideo, Ser. 2, 8: 175, where it had been placed by Gallardo, 1961, 1° Reunion Trab. Comun. Cienc. Nat. Geograf., Univ. Nac. Litoral, Santa Fe, Argentina: 209, and Braun and Braun, 1979, Iheringia, Zool., 54: 7-17. See Lavilla and Cei, 2001, Monogr. Mus. Reg. Sci. Nat. Torino, 28: 33-34, for summary of recent literature and confusion with Melanophryniscus montevidensis. Kwet and Miranda, 2001, Herpetofauna, Weinstadt, 23: 19-27, provided an account and discussion of distribution and ecology. Langone, 1995 "1994", Mus. Damaso Antonio Larrañaga, Ser. Divulg. 5: 28-29, and Achaval and Olmos, 2003, Anf. Rept. Uruguay, ed. 2: 14, provided for the Uruguayan population a brief account. Brusquetti and Lavilla, 2006, Cuad. Herpetol., 20: 20, briefly discussed the range in Paraguay. Maneyro and Kwet, 2008, Stuttgart. Beit. Naturkd., Ser. A, Neue Ser., 1: 95-121, provided comments on taxonomy, implying the possibility that Melanophryniscus atroluteus and Melanophryniscus montevidensis might be conspecific. Céspedez and Motte, 2007, FACENA, 23: 31-42, mapped the distribution in Paraguay. Baldo, Maneyro, and Laufer, 2010, Zootaxa, 2615: 66-68, reported on larval morphology.
