apex abruptly angular; snout is short, bluntly angular, the tip not extended, the anterior margins almost straight to weakly undulate; eyes large, protruding, length of orbit and spiracle, ca. 1.4 in snout length, the interorbital space subequal to orbit length; mouth is very small, with 2 broad central oral papillae, the labial furrows and folds prominent, the jaws asymmetric; nasal curtain skirt-shaped, rather narrow, the margin concave, strongly fringed; nostrils narrow; skin often lacking denticles and thorns; tail firm, broad based and depressed slightly anteriorly, tapering gradually to caudal sting, it is slender, almost rounded below sting, flattened posteriorly (not long and
whip-like), the length slightly longer than DW, with usually 1 caudal sting, its ventral fold low, elongate, base ca.1.5 times distance from snout to 5th gill slit, the dorsal fold short based, lower than ventral fold; pelvic fins are large, the apices rather pointed (Ref. 114953).
