 large and strong palps. First pair of swimming feet two-branched, branches two-jointed ; 

 cuter branches of the first, second, and third pairs armed with curiously-formed laminae. 

 Fourth pair rudimentary, two-jointed, one-branched. Carapace produced backwards into 

 two long, narrow processes. Antennal palps, sucking-discs, and furcula wanting.

 This genus differs from Pandarus in that the cephalothoracic segments are destitute 

 (or nearly so) of lateral alse, and are not bilobate; the abdomen is well developed, and its 

 segments distinct: there is no rounded telson, and the caudal stylets are laminar, terminal, 

 and bear setaa of the true Cyclopoid type.
