Deep body, relatively slender toward the end of caudal peduncle; maximum body depth slightly anterior to origin of dorsal fin in specimens 6 - 10.45 cm SL and at the level of the pectoral fin base in smaller specimens. Pectoral fins short, far from reaching origin of dorsal fin. Radial grooves present in the hind part of operculum.
