Diagnosis. Rostrum prominent, about 0.5 times length of ocular scale. Lateral projections of carapace very low. Eyestalk swollen at base, ocular scale with 1 blunt spine. Major cheliped with merus essentially smooth, carpus with 3 prominent spines along distal margin, 2 rows of longitudinal spines. Palm of chela with 9–12 tubercles forming oblique ridge from articulation of movable finger to carpus; outer, inner margins lined with tubercles, small tubercle in depression extending from fixed finger toward carpus; 4 minute tubercles in row on inner side beneath inner dorsal margin; entire upper margin lined with setae. Movable finger with 2 or 3 tubercles in row; outer edge with row of tubercles. Minor cheliped thinner; merus with 6–8 spines on lower, outer distal margin; carpus with 2 close-set subparallel rows of spines; palm with median longitudinal row of tubercles, single outer proximal marginal tooth, row of 9–11 outer, distal marginal teeth. Movable finger with 1 or 2 minute tubercles in proximal half; lateral teeth obscure. Pereopods 2, 3 with short dactyls having 8 spines in longitudinal row. Telson symmetrical, with transverse suture, terminal margins armed with series of small teeth.Uropods asymmetrical. Carapace length 13.8 mm.
