Snout posterior to mandibular symphysis. Nostrils single, about on horizontal with top of pupil, close to anterior margin of orbit. Mouth oblique, its angle about 30°, upper jaw included, its symphysis anterior to snout. Mandibular symphysis strong but lacking a prominent knob. Premaxillary teeth slender canines, inner teeth larger and sharper than outer ones, forming a narrow band of about 25 oblique rows of up to 7 teeth each; teeth apparently more closely set than in lower jaw. Narrow symphyseal gap present. Mandibular teeth larger and longer than premaxillary teeth, the largest innermost and nearest symphysis, slender with rounded tips; more posterior teeth sharp, lanceolate, forming a narrow band of about 25 oblique rows of up to 6 teeth each, the band gradually and slowly increasing in width anteriorly; symphyseal gap absent. Eye large, prominent, slightly more than 25% HL; orbit almost 30% HL. Gill opening above pectoral fin and extending ventrally in front of 12 fin rays, most of its length below opercular spine. Gill rakers on first arch 12/9, dorsal ones alternating, ventral rakers opposite. Spinules forming a V-shaped patch on each raker, generally with no clear pattern but a few rakers with two clear rows within more numerous scattered spinules. Opercle strongly curved posteroventrally, its posterior part almost horizontal and on a level with midline of body. Pore formula unknown, coronal pore apparently absent; symphyseal pores missing.</paragraph>
