Resumo: | A new species of Gladioglanis is described from a single locality on rio Aripuanã, rio Madeira basin, and can be distinguished from its congeners by the following characters: dorsal-fin spine and spinelet absent, first dorsal-fin ray flexible, unbranched, followed by five branched dorsal-fin rays, pectoral-fin spine short and with few (5 anterior-side, 4 posterior-side) dentations, 22-25 anal-fin rays, round profile of the head in dorsal view, first dorsal-fin pterygiophore in contact with the neural spine of eighth vertebrae, 13 caudal-fin rays in both upper and lower lobes, and 60 total vertebrae. Some of its characters are discussed below and compared among the species of a small clade within Heptapteridae proposed by Bockmann (1998).
