Lobulation on the anterior two thirds of carapace distinguishable, but faint owing to the presence of fine grooves which are separating them, and absent in posterior third. The entire surface of the carapace, grooves, as well as lobules, covered with minute, sharp and crisp granules, which are larger in the middle of the branchial regions. First of the four antero-lateral lobe is shallow. Chelipeds and legs are crsiply granular as in carapace, but the carapal and propodal joints show no dimples. Anterior male pleopod narrow, curved, with acutely pointed apex which is strongly curved outward; inner sub-apical region adorned with 7-9 long setae followed by three claw like spines, outer side of this region armed with rows of spinules.
