Abstract:
Based on well preserved cranidia and pygidia from the Chefu Formation(early Late Cambrian) of Jimachong, Wanshan District, eastern Guizhou, South China, the genus Protaitzehoia Yang, 1978 is here revised and transferred from Damesellidae to Ordosiidae. 2 new species and 1 new subspecies are established, namely: Protaitzehoia latelimbata sp. nov., Protaitzehoia nitida sp. nov., and Protaitzehoia quadrata jimachongensis subsp. nov.
