Description

Carapace shorter than abdomen and longer than pereon; abdomen longer than carapace and pereon together. From a dorsal view, the carapace appears laterally compressed anteriorly. Antennal notch as a subacute incision, with an antero-lateral corner with the acute tooth. With ocular pigment. The first pereonite is visible only above the lateral mid-line. Pereonite 2 with ventrolateral expansion overriding pereonite 1 and carapace. Pereonite 3 extended forwards and backwards overriding pereonites 2 and 4. Pereonite 4 with ventrolateral expansion overriding pereonite 5. Pereopods 1 with exopod. The whole width of the terminal end of pleonite 6 slightly extended between the bases of the uropods; the apex rounded. Uropodal endopod uni-articulated. Uropodal exopod bi-articulated, with proximal article shorter than distal one. Uropodal peduncle longer than rami. Rami is approximately the same length. Males with three pairs of pleopods (Fig. 2 C).
