a). Twelve growth lines more or less equidistant from each other, each raised as a narrow band, carapace opaque, brown in colour and with rough surface. Distinct umbo, dorsal margin depressed in umbo region and humped asymmetrically posterior to this, greatest elevation at about two-fifths of the length; dorsal margin largely smooth without dorsal serration, but minor depressed steps at each of last two to three growth lines. Dorso-anterior and dorso-posterior angles distinct, about 110° each; both anterior and posterior carapace margins markedly convex and protruding from the dorsal angles, ventral margin broadly convex.

The number of antennomeres in each ramus of the second antenna varies from zero to 18; the first condition was observed in a few specimens, possibly due to accidental loss through predation, but the most common number is around 16–17 antennomeres. The number of spines and setae on the antennomeres varies, largely according to position of the along the flagella, but also somewhat randomly in that those at mid length may have four to nine spines and six to twelve setae instead of the standard six and around ten respectively.

is unusual among its congeners in that sexual differentiation is minimal. The carapaces of males and females are indistinguishable in shape and size, but there are differences in the length of the first antenna and in the length and shape of the rostrum. Furthermore, the last spine of the telson in males is almost always angled differently on either side.
