Halocypridina
Halocypridina is a suborder of the Halocyprida order of seed shrimp, along with the Cladocopina. Ostracods of this group often have a dorsoposterior spine on the carapace. The adductor muscle scars show various patterns, in contrast to those of the Cladocopina, which are in a triangular pattern or a half-rosette. A sixth limb is present. The group is divided into the Halocypridae and the Thaumatocyprididae.
