Discodactylus Wagler, 1833 .

The name Discodactylus was coined for the individuals depicted in figures 1 to 5, plate 71, of Seba (1734), the same plate and figures mentioned by Rolander (see above). The figures represent two different species, named by Wagler Discodactylus tibicen (figs. 1–2, males; 3 female) (a replacement name for Hyla tibiatrix Laurenti, 1768 and Calamita tibicen Merrem, 1820 ), and Discodactylus marmoratus (figures 4 and 5) (a replacement name for Hyla marmorata Daudin, An XI). The name Discodactylus was coined by Wagler to replace the names Hyla and Calamita due to their apparent inadequacy.

Although Discodactylus Wagler 1833 antedates Trachycephalus Tschudi, 1838 , Wagler’s name fits the considerations of Art. 23.9 of the Code (IZCN 1999) and, consequently, it is possible to apply the reversal of precedence. Discodactylus and its contained species ( Discodactylus dumerili , D. marmoratus , D. phacophorus , D. pulcher , D. ruber , D. tibicen , and D. tuberculatus ) were included in Sherborn (1932) Index Animalium, but it was never used again in reference to an amphibian, being ignored to the point that Fitzinger (1843: 18; 95) used it to name a genus of geckos, fulfilling the requeriments of Arts. 23.9.1.1 and 23.9.6. In turn, Trachycephalus has been used extensively, e.g., just in the last five years, by at least Abrunhosa et al. (2006); Acosta-Galvis et al. (2006); Alvarez et al. (2009): Barrio-Amoros and Brewer-Carias (2008); Bastazini et al. (2007); Bernarde (2007); Borges and Freitas (2007); Borges-Martins et al. (2007); Brandão and Araújo (2008); Cabagna Zenklusen et al. (2009); Cintra et al. (2009); Cisneros-Heredia (2006; 2007); De Freitas and Oliveira Lima (2009); Faivovich et al. (2005); Frost et al. (2006); Jungfer (2010); Kok and Kalamandeen (2008); Kwet and Sole (2008); Pimenta and Canedo (2007); Ramirez Valverde et al. (2009); Rigolo et al. (2008); Rodrigues et al. (2005); Rodrigues (2008); Wilms et al. (2005); Wogel et al. (2006); and Ziegler (2008), fulfilling the requirements of Art. 23.9.1.2.

In conclusion, we consider Trachycephalus Tschudi, 1838 as nomen protectum and Discodactylus Wagler, 1833 as nomen oblitum.
