The eyes are small and slightly oval. The basal segment of the first antennular peduncle of the male has several strong setae, but no processes. The second segment has a distal, which extends over the third segment. There are no strong setae on the basal segment of the first antennular peduncle of the female, but the upper terminal margin has a small flat process, pointing upward and visible from the side. The second segment has a much smaller lobe than in the male, which terminates in an angle. There are no processes on the third segment of the peduncle in either sex.
