Dasyloricaria capetensis |
Dasyloricaria is a genus of catfishes (order Siluriformes) of the family Loricariidae. It includes five species, D. capatensis, D. filamentosa, D. latiura, D. seminuda, and D. tuyrensis.[1]
[edit] Distribution
The distribution of Dasyloricaria includes the northwestern South America on the Pacific slope of Colombia and Panama. Its distribution is restricted to the Pacific slope of the Andes, which is a unique pattern of distribution within the subfamily.[2] D. capatensis and D. tuyrensis originate from the Tuira River basin.[3][4] D. filamenosa inhabits the Magdalena River basin and possibly the Catatumbo River.[5] D. latiura is distributed in the Tuira and Atrato River basins.[6] D. seminuda is found in the Magdalena River basin.[7]
[edit] Description
Sexual dimorphism is similar to that of the Rineloricaria group, including hypertrophied odontodes forming brushes on the lateral surfaces of the head in mature males and papillose lips. However, it is also morphologically similar to members of the Loricariichthys group. It shares deep postorbital notches,an abdominal cover strongly structured, and a similar mouth shape; hypertrophied development of the lower lip has also been reported, a characteristic of representatives of the Loricariichthys group, suggesting that Dasyloricaria is also a lip brooder. Finally, with some representatives of the Loricaria group, it shares a triangular head, strong predorsal keels, and the upper caudal fin ray produced into a long whip. Dasyloricaria could represent a link between all other morphological groups.[2] D. capatensis grows to 16.4 centimetres (6.5 in) SL.[3] D. filamentosa grows to about 26.0 centimetres (10.2 in) SL.[5] Both D. latiura and D. tuyrensis grow to about 35.5 centimetres (14.0 in) SL.[6][4] D. seminuda grows to 18.2 centimetres (7.2 in) SL.[7]
