Carapace sub-circular or longitudinally sub-oval, with a small denticle at the junction of the anterolateral and postero-lateral borders.

Carapace conspicuously longer than broad, than its surface, like the anterior half there are also some small tubercles, most of which fall into seven nearly longitudinal rows, one row being in the middle line. The antero-lateral borders are very finely crenulate. The convergent postero-lateral borders, and the posterior border are very finely and closely beaded. The outer parts of the pterygostomian and sub-hepatic regions are covered with a felt of fine short hairs. The front is bidentate and projects beyond the level of the orbits; the latter occupy all the rest of the anterior border. The antennary flagella are very short. The transverse ridge at the distal end of the arm is granular, and is armed with three spines gradually increasing in size from within outwards; the upper surface of the wrist has several small tubercles. The crest of hand contain 8 denticles. The last pair of legs has its four terminal joints distinctly lamellar.The carina of the second abdominal tergum in both sexes trilobed, the middle lobe being much smaller than the lateral lobes.

The chelipeds and abdomen in both sexes are as in Calappa and Nursia. In the majority of species the second abdominal tergum, in both sexes, is strongly carinate transversely as in Nursia.
