Description
Size: 18 mm(max Length))

The body is more or less cylindrical; the three frontal lobes are relatively short and wide. The median lobe is triangular and sub-acute and is separated from the lateral lobes by a distance greater than its own breadth at the base. The transverse rugae on the dorsal surface of the carapace are quite prominent in the area between the cardiac region and the frontal lobes. The rugae are relatively farther apart, more frequently interrupted and more or less obliterated on the sides and towards the posterior margin of the carapace. The carapace shows well marked post-frontal and post-gastric furrows. The lateral border of the carapace is minutely serrulate in its anterior half. The ocular peduncles are slender and long, reaching well beyond the teeth of the second segment of the antennal peduncle. The antennules are densely hairy. The second segment of the antennal peduncle bears distally three spines with horny tips, of which the median one is the longest. There is one indistinct minute oblique longitudinal ridge armed with relatively long, fine, seta-like spinules, slightly away from, but posterior to the median tooth. Basally the inner margin of the dorsal tooth is similarly armed with fine spinules. The antennal flagellum is nearly as long as the carapace, multiannulated and ciliated on the outer margin. The outer antero lateral angle of the external margin of the merus of the third maxilliped is rectangular and not produced; the antero-internal lobe is low triangular, distally rounded and little prominent. The dactylus of the first leg, in length, is more than twice its width and terminates in a spine distally. It usually bears four distinct spines on the lower margin but no teeth on the upper margin. The dactyli of the second and third legs are falcate, broad at the base; in the distal half narrow, sub-acute and thin.
