. Body depressed, encased in bony plates. Eyes not visible in ventral view. Rostrum of male long, club-shaped, with many small surface spines; that of female very short, pointed. Mouth small, inferior, toothless. Gill opening restricted to small dorsolateral hole behind head. Two rows each with two small tubercles on dorsum of head. Carapace comprising three pairs of dorsal plates (d1-3), four pairs of dorsolateral plates (dl1-4), paired superior pectoral-fin plates (pp.s.), and two paired extralateral plates (el1-2); rounded hump-like tubercles on each dorsal plate (d1-3); small posteriorly directed tubercles on lateral edges of each dorsolateral plate (dl1-4). [KAUM-I. 47680 with hook-shaped tubercle between paired dorsal plates (d2); absent in KAUM-I. 47679 and 47681]. Plastron comprising five paired ventrolateral plates (vl1-5), paired gular plates (g), pectoral plates (p), ventral plates (v), anal plates (a) and inferior pectoral-fin plates (pp.i.) and an unpaired pre-anal plate (ip). Anus located between preanal plate and tail ring I. KAUM-I. 47679 with 6 inwardly directed spines (7 and 5 in KAUM-I. 47680 and 47681, respectively) on dorsal surface of ventrolateral plate (vl1). Small central tubercles on each pectoral and ventral plate; interventral and pre-anal plates with bulge, the latter plate with posteriorly directed tubercle; small, posteriorly directed tubercles on lateral edges of each vl2-vl4. Tail elongate, with 11 tail rings (I-XI); 9th and 10th tail rings fused together, anterior 8 rings mobile; small, posteriorly directed tubercles on corners of each tail ring, their tips sharply pointed; tubercles smaller on posterior tail rings; anteriorly directed spines on anterior of tubercles on tail rings IX, X, and XI; two paired caudolateral plates overlapping junctions between tail rings II and III and IV and V; dorsal surface of last tail ring lacking spine. Wing-like pectoral fins large, inserted horizontally, with 11 rays (10 and 12 rays on left and right side, respectively, in KAUM-I. 47679), 5th ray stout, thicker than other rays. Pelvic fins with 1 spine and 2 rays; each pelvic fin separated without membrane, inserted into an unpaired interventral plate; first spine very long, extended posteriorly. Dorsal and anal fins short, each with 5 soft rays, extending from center of dorsal and ventral tail ring II to center of tail ring IV, respectively. Caudal fin with 8 unbranched rays.
