Cypridocopina is a suborder of ostracods in the subclass Podocopa, order Podocopida. It is divided into three superfamilies – Cypridoidea, Macrocypridoidea and Pontocypridoidea. [1]
Ostracods, or ostracodes, are a class of the Crustacea, sometimes known as seed shrimp. Some 70,000 species have been identified, grouped into several orders. They are small crustaceans, typically around 1 mm (0.039 in) in size, but varying from 0.2 to 30 mm in the case of Gigantocypris. Their bodies are flattened from side to side and protected by a bivalve-like, chitinous or calcareous valve or "shell". The hinge of the two valves is in the upper (dorsal) region of the body. Ostracods are grouped together based on gross morphology. While early work indicated the group may not be monophyletic; and early molecular phylogeny was ambiguous on this front, recent combined analyses of molecular and morphological data found support for monophyly in analyses with broadest taxon sampling
The Podocopa are a subclass of ostracods. This subclass can be differentiated from the other subclass (Myodocopa) by the morphology of the second antenna: the Podocopa have a relatively long endopod, whereas the Myodocopa have a relatively long exopod. The seventh limb of the Podocopa has a variety of forms or is absent, but is never an annulated worm-like limb. Within the Podocopa there are three orders: Platycopida, Podocopida and Palaeocopida.
The Podocopida are an order of ostracods in the subclass Podocopa. It is divided into five suborders – Bairdiocopina, Cypridocopina, Cytherocopina, Darwinulocopina, and Sigilliocopina. It is the most diverse of the four orders of ostracods, and also has a rich fossil record.
