Özet

We describe a new genus, Ufocandona gen. nov. with its type species Ufocandona hannaleeae gen. et sp. nov., from an artesian well in San Marcos, Texas, USA. The new genus has diagnostic characteristics that distinguish it from other genera in Candonidae, including the asymmetric shape of the valves, the smooth central area on the external surface of the valves, the hexagonal ornamentations around the marginal ends of the carapace, the dense spines on the marginal edges of the right valve and the dorsal prolongation and tubercles seen from inside the ventral edges of the left valve. Additional differences in the soft body parts of the male and female (e.g., claw-like uropod, shape of hemipenis, long Y aesthetascs, two short or reduced exopods on antenna, reduced numbers of setae and segments on other extremities) distinguish the new genus from others in the family. The discovery of this species from a deep artesian well contributes important information to our understanding of groundwater species diversity in a biologically diverse aquifer where the ostracod fauna has been unstudied.
