Ostracoda from Lee Point on Shoal Bay, Northern Australia: Part 3, Podocopina (Cytheracea)

The littoral environments present in Shoal Bay, Northern Territory (Australia) show a high diversity of ostracods cytheráceos (51 genera and 97 species). Probably this diversity is due to three factors: (1) marine environments warm and well oxygenated leading to a high level of biological productivity, (2) shallow marine environments favorable for the accumulation of material conchífero post mortem, and (3) a location central in the way of dispersal on the continental shelf between the regions of the Pacific and Southeast Asia. A particular feature of this fauna Cytherscea is that some genres, such as Alocopocythere, can be traced back to the Cretaceous when it first appeared in the shallow waters of the Tethys. In this overlay component of the ancient ostracods are the dominant fauna in partnerships of the modern Indo / Pacific, such as gender Keiji. While the Cytheracea ostracods are the dominant groups, especially the Cypridacea marine Bairdiacea and Plstycopina, are well represented and are quite different (fide Whatley et al., 1995, 1996). We describe here a new genre, Paraxestoleberis, and 15 new species: Dentibyíhere multituberosa, Dampiercythere papillolineata, Neocyíheromorpha papilloporosa, Loxoconcha catasíeros, Semicyrherura gamma, Callistocyíhere cookei, Loxocorniculum koolpionyahensis, Keúia interim, K. profundosculpia, K. parademissa, Quasibradleya leepoiníensis, Actinocyíhereis gippsi, Henryhowella sinespinosa, Poníicocyíhereis spatulospinosa and Paraxestoleberis posteroacuminata. Due to the limited material obtained, 16 species are kept in open nomenclature: Bythoceratina sp. Corallicyíhere sp. Venericythere sp. Tanella sp. Loxocorniculum sp. 1 L. sp. 2, Gambiella sp. Javanella sp. Paradoxostoma sp. Neomonoceratina sp., Bradley (sl) sp. Echinocytbereis (sl) sp. Plaíycyíhereis? sp. Alocopocyíhere sp. Xestoleberis sp. and Paraxestoleberis sp. The remaining 66 species have been described previously in other areas.
