is an easily distinguished species with an enlarged round head lacking a supraocular depression and with a reduced rostrum from which long antennules hang. Other diagnostic features are the long and unequal bident tooth near the basal claw and a well-developed proximal pecten with 11– 15 strong spines. On the first thoracic limb of females, the anterior seta on the third endite is present. The ephippium bears a single egg and males have long antennules with 4 apical ‘hooks’, a first limb lacking an ODL, and unusually strongly developed copulatory hooks.
