Total lateral scales 33; transverse scales 2/5. Vertebrae: 10 precaudal, 25 caudal. Mandibular pores: 3+1+3. Head 3.2-4.0 in SL; eye 2.4-3.0 in head length. Small fish, seldom longer than 20 mm SL. Body slender, scales large, nape scaled, abdomen naked. Pelvic fin rays slender, united by membrane for half the length of the longer ray. First dorsal fin about half height of second. Pectoral fin large, longest ray reaching to penultimate spine of second dorsal fin. Mouth oblique, small and pointed, maxilla reaching vertical through anterior margin of orbit.
