Abstract

A new species of Neotropical freshwater sciaenid, Pachyurus stewarti, is described from the Río Napo basin, Ecuador. The new species is readily distinguishable from its congeners by having a unique coloration pattern of about twelve brownish vertical oval blotches and bars on the lateral surface of the body from the opercle to the caudal peduncle, and a longitudinal stripe which starts below the soft dorsal-fin base and extends along the mid-line of the caudal peduncle to the base of the caudal fin.
