Left view of female Vargula norvegica, from Benson et al. (1961).

Belongs within: Myodocopida.

The Cypridinidae are a group of relatively large planktic ostracods, often over two millimetres in length.

Characters (from Benson et al. 1961, as Cypridininae): Carapace more or less strongly calcified, usually smooth; dorsal border arched, anterior margin of rostrum evenly curved or sinuous. Mostly rather large forms (more than 2 mm); sexual dimorphism weak or absent.
