Bryconamericus macarenae n. sp. (Characiformes, Characidae) from the Güejar River, Macarena mountain range, Colombia.

The article discusses a study which described a new species of Bryconamericus macarenae from near La Macarena mountain in Colombia based on 174 species using morphometric, meristic and osteological characters. The 21 morphometric characters used to describe the species were evaluated by principal component analysis (PCA) using the Burnaby method. The new species differs from congeners in terms of having an incomplete lateral line and fewer perforations in the latero-sensorial canal of the extrascapular bone. Also included is a key species of Bryconamericus known from the Orinoco Basin and the Catatumbo River.
