Five new ostracode genera and their type species are described from among 42 taxa obtained from silicified residues from the Quadrithyris brachiopod Zone and the upper pesavis and lower sulcatus conodont Zones of the McMonnigal Limestone at Ikes Canyon, Dianas Punch Bowl quadrangle, Nye County, Nevada. These are the beyrichiaceans Pseudomyomphalus spicatus n. gen., n. sp., and Dolichoscaphoides copelandi n. gen., n. sp., the hollinacean Eurekabolbina torquata n. gen., n. sp., the kloedenellacean Elenamarginia polenovae n. gen., n. sp. and the quasillitacean Prosumia peterseni n. gen., n. sp. Three of the five genera also occur in the partially correlative Windmill Limestone of Eureka County, Nevada, and may prove useful for interbasinal correlation.
