Comment

Frost, Grant, Faivovich, Bain, Haas, Haddad, de Sá, Channing, Wilkinson, Donnellan, Raxworthy, Campbell, Blotto, Moler, Drewes, Nussbaum, Lynch, Green, and Wheeler, 2006, Bull. Am. Mus. Nat. Hist., 297: 129, Van Bocxlaer, Biju, Loader, and Bossuyt, 2009, BMC Evol. Biol., 9 (e131): 1-10, and Van Bocxlaer, Loader, Roelants, Biju, Menegon, and Bossuyt, 2010, Science, 327: 679-682, placed Melanophryniscus as the sister taxon of remaining bufonids (although they did not study Truebella), and this was corroborated by Van Bocxlaer, Loader, Roelants, Biju, Menegon, and Bossuyt, 2010, Science, 327: 679-682. McDiarmid, 1971, Sci. Bull. Nat. Hist. Mus. Los Angeles Co., 12: 49 (and Graybeal, 1997, Zool. J. Linn. Soc., 119: 297-338), considered Melanophryniscus to be most closely related to Dendrophryniscus. Cannatella, 1986, Herpetologica, 42: 197-205, regarded it as the sister taxon of Dendrophryniscus plus Oreophrynella. Prigioni and Langone, 1987 "1986", Comun. Zool. Mus. Hist. Nat. Montevideo, 11: 1-11, supplied a key to the Melanophryniscus tumifrons group. Graybeal and Cannatella, 1995, Herpetologica, 51: 121, presented evidence supporting the monophyly of this taxon. Céspedez and Alvarez, 2000 "1999", FACENA, 15: 57-67, provided a key to the species of the Melanophryniscus stelzneri group. Larson, de Sá, and Arrieta, 2003, Acta Zool., Stockholm, 84: 145-154, discussed larval morphology in light of phylogenetic comparisons with other taxa. Cruz and Caramaschi, 2003, Bol. Mus. Nac., Rio de Janeiro, N.S., Zool., 500: 1-11, discussed the Melanophryniscus stelzneri group and defined the three species groups: Melanophryniscus stelzneri group (Melanophryniscus atroluteus, Melanophryniscus cupreuscapularis, Melanophryniscus dorsalis, Melanophryniscus fulvoguttatus, Melanophryniscus klappenbachi, Melanophryniscus montevidensis, Melanophryniscus rubriventris, Melanophryniscus stelzneri); Melanophryniscus tumifrons group (Melanophryniscus cambaraensis, Melanophryniscus devincenzii, Melanophryniscus macogranulosus, Melanophryniscus orejasmirandai, Melanophryniscus pachyrhynus, Melanophryniscus simplex, Melanophryniscus spectabilis, and Melanophryniscus tumifrons); Melanophryniscus moreirae group (Melanophryniscus moreirae). Caramaschi and Cruz, 2002, Arq. Mus. Nac., Rio de Janeiro, 60: 303-314, discussed the Melanophryniscus tumifrons group. Céspedez and Motte, 2001, Bol. Asoc. Herpetol. Esp., 12: 71-76, discussed the distribution of species in Argentina and Paraguay. Kwet, Maneyro, Zillikens, and Mebs, 2005, Salamandra, 41: 3-20, discussed the Melanophryniscus stelzneri group and provided a key. Céspedez and Motte, 2007, FACENA, 23: 31-42, provided a key to the species of Paraguay. Bidau, Martí, and Baldo, 2011, J. Herpetol., 45: 66-74, reported on body size morphometrics. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583, in their study of Genbank sequences, confirmed the monophyly of this taxon, its placement as the sister taxon of remaining bufonids, and provided a tree of exemplar species. Baldo, Cotichelli, Pereyra, Borteiro, Netto, Kolenc, Brusquetti, and Bidau, 2012, J. Herpetol., 46: 25-32, discussed karyology of the genus, which confirmed the Melanophryniscus tumifrons group and suggested that phylogeny within the taxon requires further evaluation.
