Polycopidae is a family of marine ostracods. Its members are related to animals in the suborder Halocypridina, but are sufficiently distinct to be placed in their own sub-order, Cladocopina. There is speculation that a separate order may be warranted.〔 The genera in the family differ from the other suborder, Halocypridina, in several features: the central adductor muscle scars are in a triangular (3 scars) or half-rosette (15 scars) pattern, they lack sixth and seventh limbs, and the maxilla (=fourth limb) has both an exopod and endopod (the maxilla in the Halocypridina lacks an exopod). The following genera are included:〔(【引用サイトリンク】url=http://species.wikimedia.org/w/index.php?title=Polycopidae&oldid=1697820 )〕 *''Archypolycope'' Chavtur, 1981 *''Axelheibergella'' Briggs, 1997 *''Chavturopsis'' Bonaduce & McKenzie, 2004 *''Eupolycope'' Chavtur, 1981 *''Hexopolycope'' Chavtur, 1981 *''Hyphalocope'' I.
