Camilo Andrés Roa-Fuentes, Juan Carlos Alonso, Alexander Alfonso, Mark Sabaj Pérez

Abstract

This note presents the first record of the genus Astrodoras Bleeker, 1862 (Siluriformes, Doradidae) in the Colombian Amazon (Amacayacu National Park). The single species described for the genus is A. asterifrons (Kner, 1853), reported only from the Amazon River basin in Brazil and Bolivia. The Colombian specimens are characterized by a gas (swim) bladder that is different from that of A. asterifrons, indicating that they represent a distinct and undescribed species of Astrodoras.
