Diagnosis for the genus (emended from Bean 2006, based on a unique combination of characters): "Small fusiform teleost of standard length reaching 98 mm and about 150 mm maximum length. Snout length approximately half of the orbital diameter; cranial length is 90% of body height. All cranial bones without ornamentation; at least two large pores of the supraorbital canal on each frontal bone. Quadrate-mandibular articulation below anterior half of orbit; hyomandibula without preopercular process; four short and broad sensory tubules on lower limb of preopercle, one at angle and one on dorsal limb. Anterior ceratohyal short; with six thin acinaciform branchiostegal rays; with four to six spathiform branchiostegal rays associated with the posterior ceratohyal. Thirty-eight to 45 vertebrae, 25 with autogenous neural arches in abdominal region and 16 with fused neural and hemal arches in caudal region; 22–26 pairs of ribs; epipleural bones in mid-body region. With 12 or 13 pectoral rays and 9 pelvic rays. Seven or eight hypurals; small diastema between hypurals 2 and 3; dorsal lobe of caudal fin has 7–10 epaxial procurrent rays; ventral lobe has two segmented procurrent rays and 4–6 unsegmented procurrent rays.
