Abstract

Carapace smooth and glabrous. Rostrum straight, lanceolate and slightly ascending, reaching to tip of basal segment of antennular peduncle, armed with 9 to 10 teeth on upper margin. Post-rostral carina feeble, becoming distinct towards posterior region of carapace. Orbital angle dentiform. Post-orbital, antennal and hepatic spines small, thin and sharp. No branchiostegal or pterygostomian spine. Cervical groove oblique, deep and broad on sides, continues with that on the other side through very faint notch on post-rostral carina. Branchiostegal sulcus originates from angle of inferiolateral curve and runs backwaters towards posterior border of carapace (fig. 28).
