Review of the andean armored catfishes of the genus Dolichancistrus Isbrücker (Siluriformes: Loricariidae) Neotropical Ichthyology
Ballen,Gustavo A.; Vari,Richard P..
The loricariid catfish genus Dolichancistrus is reviewed and four species recognized. Species of Dolichancistrus are distinguished from each other by the degree of development of the pectoral-fin spine, the form of the distal margin of the pelvic fin, the relative size and form of the cheek plates, the pattern of odontodes along the margin of the snout, the presence versus absence of a buccal papilla at the premaxillary symphysis, and the relative lengths of the anal- versus pelvic-spines. Dolichancistrus atratoensis is known from the río Atrato system and the río Cubarradó on the Pacific versant of Colombia; D. carnegiei occurs in the eastern río Magdalena basin in the departments of Boyacá and Santander, Colombia; D. cobrensis inhabits southern...

Taxonomic revision and phylogenetic relationships of Dasyloricaria Isbrücker & Nijssen, 1979 (Siluriformes: Loricariidae), with description of a new species Neotropical Ichthyology
Londoño-Burbano,Alejandro; Reis,Roberto E..
ABSTRACT A taxonomic revision and phylogenetic analysis were completed for Dasyloricaria . The genus includes three valid species: D . filamentosa and D . latiura previously included in the genus, and a new species described herein. Dasyloricaria have a restricted trans-Andean distribution, with D . filamentosa occurring at the lower and middle Magdalena, lower Cauca, and Sinu in Colombia, and lago Maracaibo basin in Colombia and Venezuela; D . latiura in the Atrato and the Tuyra basins in Colombia and Panama, respectively; and the new species in the upper and middle Magdalena basin in Colombia. New synonyms for D . filamentosa and D . latiura are proposed, and a lectotype is designated for the latter. Dasyloricaria is herein recognized as monophyletic,...
