In dorsal view carapace oval, anterior end pointed, posterior bluntly rounded. Lateral sides only slightly arched. LV overlaps RV along entire free margin. Two conspicuous inner lists running parallel on the inner calcified lamella, more pronounced in the anterior part. Maxillary palp with cylindrical terminal palp segment, about twice as long as broad. Two teeth setae of the third maxillary endite serrate. Maxilliped (T1) with c-seta. Walking leg (T2) with only one seta (d1) at the basal segment.
