Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. J. Jones 2010 (Geisinidae) | Presumed podocopine ostracods (superfamily unknown) being provided with weak and small duplicatures, (to a certain degree) showing common carapace characteristics: valves basically subrectangular in lateral aspect, distinctly sulcate, slightly aymmetrical, while showing right over left overlap (as a rule, most distinct along ventral margin); ridge and groove hingement developed, hinge typically bipartite, with conspicuous stragulum, posterior part channelled; lateral spines present; valve surface delicately reticulate; females showing inflated posterior part of carapace (lacking kloedenellid inner partition). |
