Memana gen. nov.

Diagnosis. Maxilliped palp 1-articulate. Telson entire. Type species. Memana sarda sp. nov.

Etymology. The genus is named for the town of Memana on Flinders Island in Bass Strait.

Species composition. Memana contains only one species, Memana sarda sp. nov.

Remarks. In Memana the flagellum of antenna 2 is very reduced and a similar reduction is seen in Boca , Perrierella and Pratinas , but it is difficult at this time to to properly assess the character state.

Memana sarda is considered to have a 5/4 setal-tooth arrangement on the outer plate of maxilla 1. It is the only aristiid with four setal-teeth on the inner row; all other species appear to have only two. We consider this to be a derived condition of the 7/4 setal-tooth arrangement which is the basic arrangement in hirondelleids, pachynids and scopelocheirids and outside the lysianassoids in the stegocephalids.
