SARMENTO-SOARES, Luisa M.; MARTINS-PINHEIRO, Ronaldo F.; ARANDA, Arion T.  and  CHAMON, Carine C.. Ituglanis cahyensis, a new catfish from Bahia, Brazil (Siluriformes: Trichomycteridae). Neotrop. ichthyol. [online]. 2006, vol.4, n.3, pp.309-318. ISSN 1982-0224.

A new trichomycterid catfish of the genus Ituglanis is described from the rio Palmares, a tributary of the rio Cahy in southeast Bahia State, Brazil. Ituglanis cahyensis is distinguished from all other congeners through a combination of characters, as the supraorbital laterosensory canal branch with pores s3 and s6 present, the low count of branched pectoral fin rays, and low number of paired ribs. It is further distinguished in proportional measurements, such as elongate nasal, maxillary, and rictal barbels, and small eye diameter.
