Cyprididae

Likely individual of Eucypris virens, copyright Ukwildlifeo.


Belongs within: Cypridocopina.
Contains: Stenocypridini.

The Cyprididae are a group of ostracods found in marine and fresh waters, with a generally smooth carapace lacking interlocking teeth in the dorsal hinge (Benson et al. 1961).

Characters (from Benson et al. 1961): Carapace variable in shape and size (to several mm in length), typically subovoid to subtriangular, with greatest height median to anteromedian, posterior end more pointed than anterior; left valve generally larger than right valve; surface commonly with tiny pits, pustules, or reticulations. Hinge line curved or rarely long and straight, consisting of groove in larger valve for reception of simple edge of smaller valve; muscle scars comprising rather compact median to anteromedian groups of four or five spots and one or two additional anteroventral spots.
