摘要：
A new species ofOdontostilbeis described from the rio Jaciparana, rio Madeira basin, Rondonia, Brazil.Odontostilbe pacaasnovosdiffers from all its congeners, exceptO. pequira, by the colour pattern. Additionally, it differs from its congeners by the terminal mouth, number of cusps in the teeth of the premaxilla (5-7), number of branched rays in the anal fin (19-22), by the shape of dentary teeth (5-7 cusps with central cusp larger and longer than laterals cusps) and by the number of lamellae of the olfactory rosette (17-18 in male and 14 in female). Morphological and molecular comparisons corroborate the distinctiveness betweenO. pacaasnovosand its congeners, justifying its recognition as a new species.
