A new ostracode species, Neomonoceratina chomentovensis sp. n., from the Korytnica Basin (Middle Miocene; Holy Cross Mountains, Central Poland)

Abstract

A new ostracode species, Neomonoceratina chomentovensis sp. n., is described from the Middle Miocene (Badenian) deposits of the Korytnica Basin (southern slopes of the Holy Cross Mountains, Central Poland). It is regarded as a descendant of N. helvetica OERTLI, 1958, known from the older Miocene deposits of both the Tethys and the Paratethys. Special attention is paid to the well pronounced sexual dimorphism in the newly established species, which is well marked even in premature individuals. Suggested· is also a value of the newly estabJdshed species in biostratigraphic zonation of the Miocene deposits of the Central Paratethys.
