Scyliorhinid catshark with a rather soft body; trunk slightly compressed, tail moderately compressed and tapering slightly to caudal fin; head not depressed, height 9.1% TL, shorter than abdomen; pectoral to pelvic space 25.4% TL, 1.3 in head length; pelvic to anal space 0.8 in anal-fin base. Caudal peduncle low, elongate, anal to caudal space 1.2 of anal-fin base length; moderately compressed, width 1.7 in height, dorsal and ventral profiles longitudinally ridged by anterior part of upper and lower caudal crests. Snout short and narrowly parabolic in dorsoventral view, tip broadly rounded, conical in lateral view; preoral length 5.7% TL, 0.7 in mouth width; prenarial snout 1.2 times eye length. Eyes large, length 3.4% TL, 5.8 in head length; eyes almost lateral on head, with well-developed subocular ridges. Labial furrows short but well developed, right lower furrow longer than upper, 1.7 and 1.2% TL respectively. Nostrils large with tube-like incurrent apertures, anterior nasal flaps sub-triangular, posterior tip expanded, forming a weak lobe; nostrils well separated, internarial length 2.3% TL; nasal flaps well short of front of mouth.</paragraph>

Dermal denticles on side small, tricuspidate, weakly imbricate, erect, densely packed; crown shield-like with a long pointed median cusp, ending in a longitudinal ridge; lateral cusps short, variably developed (cf. illustration in Last and Stevens, 1994, p. 204). Upper caudal crest well developed, extending from upper caudal margin to below second dorsal-fin rear corner, in a deep groove near its origin; elevated slightly above rest of fin; lacking a well-defined naked area at its base; denticles at lateral edge of crest mainly directed posterolaterally and slightly ventrally, largest at least twice length of tail denticles; lateral denticles tricuspidate with lateral cusps barely shorter than median cusps, separated by 3-5 rows of smaller denticles. Crest on ventral midline of caudal peduncle originating above anal-fin rear corner, but not extending onto preventral caudal margin; denticles barely larger than those of adjacent tail, some directed slightly laterally (unlike the posterior orientation of those on the flanks).</paragraph>

Pectoral fin very small, almost subcircular, lobe-like, anterior margin 7.6% TL; all margins convex, apex less rounded than rear corner. Pelvic fin relatively large, semi-oval, apex broadly rounded, length 7.3% TL. Anal fin triangular, slightly lower than second dorsal fin, base 9.7% TL; its base length about equal to interdorsal space; origin below anterior half of interdorsal space, anal-fin height 2.1 in base length. Caudal fin very short, dorsal caudal margin length 20.2% TL; upper and lower lobes originating from caudal crests; lower lobe moderately developed distally; terminal caudal lobe fan-like, bilobed, with a deep median notch.
