Two new marine peritrich ciliates, Pseudovorticella dingi nov. spec. and Pseudovorticella wangi nov. spec. were collected from coastal waters of Qingdao, China. Their living morphology, infraciliature and silverline system were studied using light microscopy and silver staining methods. Pseudovorticella dingi is characterized mainly by the apically located contractile vacuole and the presence of pellicular granules. There are 28-36 and 13-18 transverse silverlines above and below the trochal band, respectively. Infundibular polykinety 3 is composed of three rows, with row 1 conspicuously shorter than the other two. P. wangi is distinguished mainly by having two ventrally located contractile vacuoles. There are 17-20 and 9-11 transverse silverlines above and below the trochal band, respectively. Abstomal end of row 1 of infundibular polykinety 3 diverges from the other two and ends alongside row 3 of infundibular polykinety 2. Pseudovorticella plicata, P. banatica, and P. anomala have been described in Sun et al. (2009); we supplement morphometric data and photographs from life and after silver staining of these three species in the present study.
