Abstract
- Hemibrycon iqueima sp. nov., is described from small streams in the Magdalena drainage at the foothills of the western slope of the Eastern Cordillera of the Colombian Andes, Suarez municipality, Tolima Department, Colombia. The new species is distinguished from its congeners in the Magdalena-Cauca River basin by a combination of characters related to snout-anal-fin origin length, head length, dorsal-pectoral fin distance, dorsal-fin-hypural distance, postorbital distance, orbital diameter, snout length, number of total vertebrae, pre-dorsal scales, scale rows between anal-fin origin and lateral line, number of branched rays of the anal fin, maxillary teeth number and number and arrangement of hooks on the branched rays of the pectoral and dorsal fins. In addition, the validity of this species is supported by previous molecular analyses that included specimens of the new species that had been erroneously identified. Phylogenetic relationships between the new species and congeners from Pacific coast basins are discussed.
