The dorsal surface of this genus has characteristic long spines. Their frontal lamina protrude past the end of the head. Their epimera are very long, rectangular, and point outwards in a nearly horizontal direction. The first and second thoracic segment of this genus have rounded ventral lobes. Their second to seventh pereon segments have a broad triangular tooth directed forwards at the base of the external spines. Their telson is hour-glass-shaped with a long distal part and truncated apex. Their uropod protopodite is rectangular, and their exopodite is reduced.[3]
