A new species of Farlowella is described from El Carmen de Chucurí in the Departamento de Santander, western flank
of the Cordillera Oriental, río Magdalena Basin, Colombia. Farlowella yarigui n. sp. differs from its congeners in lateral
body plate morphology, abdominal cover, cephalic hypertrophied odontodes, and details of coloration. This is the first verifiable
record of the genus in the Magdalena drainage. Aspects of natural history and implications of this finding are provided
concerning the state of knowledge of the fishes of the río Magdalena Basin. Previous records of Farlowella gracilis
in the río Cauca basin are examined and herein considered erroneous, rendering the new species the only representative
of the genus in the Magdalena-Cauca system. A key to species of Farlowella from Colombia is provided.
Would very much appreciate a copy of this.
