Devonian (Eifelian) disparid crinoids from the Zeravashan range, southern Tien Shan, Uzbekistan

No Devonian disparid crinoids have been described from Uzbekistan, although parahexacrinid thecae and assorted columnals have been described in several papers in the past 50 years. Discovery of a cup of Pisocrinus and a thecae of Haplocrinites are the first of these genera known from Uzbekistan. The stratigraphic range of Haplocrinites is revised to be late Early Devonian (Emsian) to Early Carboniferous (Tournaisian) because Silurian species assigned to the genus are based on loose ossicles that morphologically do not belong to the genus. The paleogeographic ranges of Pisocrinus and Haplocrinites are extended into Uzbekistan. Haplocrinites uzbekistanensis n. sp. is described.
