Carapace broad, elliptical in shape and moderately convex in both the directions. Upper surface of carapace divided into flattened, finely granular regional lobules, separated by deep, broad, hairy grooves, these hairs are very long and fine. Surface granules are very fine, not visible to the naked eye. Posterior lobules less prominent and concealed by long pubescence. Lobular textural pattern of carapace is very much like Paractaea garretti, outer surface of chelipeds and leg joints are also similar as in Paractaea garretti.

Remarks: Paractaea sulcata can be distinguished from Paractaea garretti in having almost flat topped regional lobules, surface granules are minute; inter-lobular grooves wider, hairs on grooves are long, yellow, silky and sometimes conceal the textural pattern of carapace.
