. Dorsal contour of the body arched; ventral contour almost straight. The body height 63 % lc, contained 7.1 times in SL. Head not large, 4.4 times in SL, but rather massive; its width (70 % lc) greater than the height (63 % lc). Dorsal contour rounded to the tip of snout. Snout gelatinous, distinctly protruding above the lower jaw, 2.2 times as large as eye. Nostril looks as a pore with a raised edge, at the level of the upper edge of eye. Eye small, less than 1/5 of head length. Mouth inferior. Lower jaw slightly shorter than the upper jaw, so the edge of maxillary dental patch is visible when looking at head from below. Oral cleft extending to anterior rim of pupil. Teeth simple, elongated, in oblique rows; 5–6 teeth in a full row in front of jaws. Gill opening completely above the pectoral-fin base, reaching down to the upper ray; 1.7 times longer than eye diameter. Opercular flap large, angular and protrudes markedly back (as a result, head length is larger than predorsal length). Length of operculum is 2 times that of the eye. Cephalic pore pattern 2-6-7-1. Pores small, chin pores slightly brought together.
