Description
Size: Width 8 mm; length 6 mm

Carapace transversely oval, length is about ¾ of the width. Strongly convex. Few lobules are demarcated (by deep, wide, smooth grooves) towards the anterior two thirds of the carapace, which are covered with golden colored short hairs and bristles.
The lobules are flat and covered by crisp, vesiculus granules all over and pterygostomian region of the body, appendages and on sternum. The granules are larger near the branchial regions. Lobule 2M completely divided into two subequal lobes, the inner lobe is continuous with 1F, 2F and 1M forward. Antero-lateral border crest-like, finely granular, indistinctly four-lobed; a transverse, deep, broad groove on carapace separates the branchial region at the incision between the second and third antero-lateral lobes. Lobule 3M, and indication of 4M are well marked, other lobules are faintly marked.
Front much prolonged and produced, deflexed vertically downwards, obliquely rounded into two lobes, free margin beaded; outer corner confluent with inner supra-orbital tooth.
Upper orbital margins tumid and granular, sutures indistinct. Anterior border of merus of external maxilliped oblique.
Chelipeds equal, arm smooth, with crested and beaded anterior border. Outer surfaces of wrists and palms convex and covered with various types of granules. Lower border of palm crested and beaded; granules on upper, inner surface of palm are of gradually increasing size from upper to lower edges. Hands and legs not lobulated on their outer surfaces but granular; merii of legs with beaded, crest-like anterior edges. Scattered, stiff setae present all over the surfaces. Anterior male pleopod is a grooved, curved process, hairy and spinulose on inner subapical areas.
