Abstract
Ditaxodon taeniatus is a striped, racer-like colubrid snake inhabiting grassland savannas in southern Brazil. This species was described as Philodryas taeniatus by the then curator of the Museum für Naturkunde der Humboldt-Universität zu Berlin (formerly Zoologisches Museum Berlin, ZMB), Wilhelm Peters, from a single specimen collected by Reinhold Hensel in Porto Alegre, Rio Grande do Sul. Peters’ description was published in a paper by Hensel (1868: 331) and, according to the International Code of Zoological Nomenclature (ICZN, 1999: Article 50.1, Recommendation 51E), the correct citation is Ditaxodon taeniatus (Peters in Hensel, 1868). Later, George A. Boulenger (1896: 124) transferred Philodryas taeniatus to the genus Conophis, and Alphonse R. Hoge (1958: 54) created for it the new genus Ditaxodon, which remains monotypic today.
