摘　　要：报道了采自青岛沿海的聚缩虫两新种,倪氏聚缩虫Zoothamnium niisp.nov.和王氏聚缩虫Z.wangisp.nov.。两者分别以下列组合的性状区别于所有已知种:倪氏聚缩虫为双层口围缘、交替式分枝、69～88环的总银线数以及口区小膜3由3条平行等长的动基列组成。王氏聚缩虫为单层口围缘、交替式分枝、108～135环的总银线数以及口区小膜3由两条错位排列的动基列组成。The living morphology, infraciliature and silverline system of two new marine peritrichous ciliates, Zoothamnium nil sp. nov. and Z. wangi sp. nov. were investigated by living observation, protargol impregnation and silver nitrate methods. Z. nii can be recognized by： marine Zoothamnium with alternatively branched stalk; zooid in vivo about （70-80） μm x （40-50） μm with double-layered peristomial lip; one contractile vacuole apically located and macronucleus C-shaped; number of transverse rows from scopula to aboral trochal band 22-30 and from aboral trochal band to peristomial area 47-58; three ciliary rows in peniculus 3 closely spaced and parallel to each other. Because of the alternatively branching pattern and other extremely similar morphological features, two morphotypes, which were misidentified in previous reports, were combined with Z. nii ： Z. duplicatum sensu Kahl, 1933 and Zoothanmium sp. sensu Kahl, 1935.
