Última A new species of Copionodon lacking a free orbital rim (Siluriformes: Trichomycteridae) Neotropical Ichthyology Pinna,Mario de; Burger,Rafael; Zanata,Angela Maria. ABSTRACT A new species of the copionodontine genus Copionodon is described from the upper reaches of a tributary to the rio Paraguaçu in the Diamantina Plateau, Bahia State, northeastern Brazil. This species represents the northernmost occurrence of the subfamily yet known. The new species can be readily recognized by its large eye without a free orbital rim. Other characters such as the entirely cartilaginous second hypobranchial, and the uniformly broad irregular midlateral dark band further diagnose the new taxon. Its particular combination of characters is superficially intermediate between Copionodon and Glaphyropoma. Detailed analysis, however, indicates that it forms a monophyletic group with species of Copionodon and therefore it should be included...

ABSTRACT A new species of the Copionodontinae genus Copionodon is described from the riacho do Mosquito, tributary to rio Santo Antônio, rio Paraguaçu basin in the Diamantina Plateau, Bahia State, northeastern Brazil. This species represents the northernmost occurrence of the subfamily yet known and is a relictual population, apparently restricted to an underground sector of the stream and its immediate downstream exit. The new species can be readily recognized by the combination of the presence of opercular odontodes, the mostly uniform coloration of the body, and the lack of a free orbital rim. Despite several troglomorphic traits shared between the new species and Glaphyropoma spinosum, the two species are not closest relatives and all such similarities...
