The Podocopa are a subclass of ostracods. Members of the subclass Podocopa can be differentiated from the other subclass of ostracods (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 (as seen in some Myodocopa). Taxonomy The following orders and unplaced families are recognised in the subclass Podocopa: Order Palaeocopida Order Platycopida Order Podocopida Unplaced families Family †Pachydomellidae Berdan & Sohn, 1961 Family †Rectellidae Neckaya, 1966 Family †Rectonariidae Gruendel, 1962 References External links Arthropod subclasses
