Shares with the first two species the absence of a premaxillary foramen, present in the last three species and differs from Oligosarcus jenynsii by having a smaller orbital diameter and the tip of the pectoral fin failing to reach the pelvic-fin origin, and from Oligosarcus perdido by the presence of more horizontal scale rows around the caudal peduncle.Description: Dorsal-fin rays ii,9; anal-fin rays iv-v,22-28; pectoral-fin rays i, 13-16; pelvic-fin rays i, 7 (Ref. 85166).
