Description
Size: Width 17 mm; length 12 mm.

Carapace thick, subcircular to transverse in shape. All the lobules on the carapace are convex, separated clearly by deep, broad, smooth grooves which are covered by brown fur, mixed with long setae. The entire carapace is deeply lobulated, the granules on the lobules and appendages are thickly set, smooth and vesiculus. The lobules on the outer side of chelipeds and leg joints are of same type as on the carapace.

Anterior male pleopod stout, curved in young male, no adult male specimen with pleopod had been examined. In the subadult it is narrow and obtusely rounded apically and adorned with a long setae followed by a few short hairs.

Remarks: In Paractaea rufopunctata the entire dorsal surface of carapace is so well lobulated that its textural pattern is very well outlined and distinctive and it is difficult to be mistaken for the other allied species.
