Dasyloricaria Isbruecker & Nijssen, 1979 View in CoL View at ENA   ZBK .

Type species: Loricaria filamentosa Steindachner, 1878   ZBK .

Holotype: NMW 44874 , Colombia, Rio Magdalena drainage .

Gender: feminine.

Distribution includes the northwestern South America on the Pacific slope of Colombia and Panama. Dasyloricaria   ZBK is poorly known and no ecological data are available. Sexual dimorphism is similar to that of Rineloricaria   ZBK , including hypertrophied odontodes forming brushes on the lateral surfaces of the head in mature males. Steindachner (1878) reported hypertrophied development of the lower lip, a characteristic of representatives of the Loricariichthys   ZBK group, suggesting that Dasyloricaria   ZBK is also a lip brooder. This genus is unusual in several respects. Its distribution is restricted to the Pacific slope of the Andes, unique pattern of distribution within the subfamily, distinguishing it from the rest of the Loricariinae , although it shares morphological characteristics with representatives of other groups mainly distributed on the Atlantic slope. Along with other members of the Rineloricaria   ZBK group, it shares papillose lips and hypertrophied odontodes along the sides of the head in breeding males. With some representatives of the Loricariichthys   ZBK group, it shares deep postorbital notches, an abdominal cover strongly structured, and a similar mouth shape, including the hypertrophied lower lip of breeding males. Finally, with some representatives of the Loricaria   ZBK group, it shares a triangular head, strong predorsal keels, and the upper caudal fin ray produced into a long whip. Dasyloricaria   ZBK could represent a link between all other morphological groups. Based on sexually dimorphic characters and lip structure it is placed within the Rineloricaria   ZBK group following Isbrücker (1979). Currently, five valid species are recognized (Ferraris2003).
