The characteristics and infraciliature of a new euplotid ciliate, Euplotes qingdaoensis n. sp., discovered from the coastal waters of Jiaozhou Bay, northern China, were studied using live observation and silver impregnation. The new marine species is characterized by a slightly flattened body (90–110 μm×70–80 μm, in vivo), an adoral zone of 26–29 membranelles, 10 strong frontoventral and five transverse cirri, two caudal cirri, a single left marginal cirrus, seven dorsal kineties, a middle kinety with about 15 pairs of basal bodies, a silverline system of the double-eurystomus type, and a C-shaped macronucleus.
