Hysterocythereis

Ostracoda - Podocopida - Trachyleberididae

Discussion

LSID. urn:lsid:zoobank.org:act:1B9ED9E0-22C1-482C-9413-D7EF2BC60CF2

Derivation of name. Gr. rsq hysteros, after, later; plus Cythereis, a well-known ostracod genus. With reference to the fact that Cythereis Jones is an essentially Cretaceous genus, while Hysterocythereis occurs in both the Maastrichtian and Lower Paleocene, and is a very possible descendent. Two other species, erroneously attributed to Anticythereis by Bertels (1973, 1975a), are also included in the present genus.
