PDFAbstract
Based on 174 specimens, using morphometric, meristic and osteological characters, we describe a new species: Bryconamericus macarenae from the Güejar River in La Macarena mountain range, Orinoco Basin, Colombia. It differs from congeners in having: an incomplete lateral line (vs. complete lateral line in all except B. delta) and fewer and less conspicuous perforations in the latero-sensorial canal of the extrascapular bone (vs. conspicuous latero-sensorial canal perforation). It has four or fewer unbranched anal-fin rays (vs. five or more unbranched anal-fin rays), a short, thickened extrascapular bone without projections from the posterior margin, or with only a reduced apophysis (vs. extrascapular long, irregular, bony projections on its margins, and with a large undulated apophysis on its posterior margin). It also differs in live coloration. A key of species of Bryconamericus known from the Orinoco Basin and the Catatumbo River is included.
