Disc weakly rhombic, disc width nearly equal to disc length, disc width 1.03 times in disc length; dorsal surface with denticles and row of spines; ventral surface smooth. Body depressed, flat and slightly elevated trunk; snout short, broadly triangular or pointed, with anterior margin nearly straight to slightly concave, outer margins rounded; acute at apex with indistinct, triangular apical lobe; snout angle 110°. Five gill slits; fifth gill slit smallest; first gill slit length 5.9% of head length; fifth gill slit length 4.2% of head length; nostril narrowly oval; nasal curtain skirt like, slightly concave in middle; mouth arched, median portion of lower jaw, 3 oral papillae. Snout to maximum disc width 36% in disc width; pre-orbital length 24% in disc width. Interorbital space broad, weakly concave; eyes small, dorsolateral, slightly elevated and protruding; inter-orbital space with slope; eye diameter shorter than spiracle length; spiracle small; spiracle length 0.3 in pre-spiracular length. Denticles progressively increasing in size till caudal sting. Spines erect or angular with strong basal region (hard). Tail base width 1.5 times its depth; tapering gradually to sting base; slender and thin beyond spine origin, narrowly rounded in cross-section post spine. Caudal spine nearer to tail base.
