Abstract

Our study aimed to investigate the diversity of tintinnid species in Korea by collecting samples from coastal waters. As a result, we identified and redescribed three newly recorded species of the genus Tintinnopsis Stein, 1867 and one previously recorded species of the genus Antetintinnopsis Wang et al., 2021 in Korea. The loricae morphology and molecular phylogeny based on the 18S rDNA sequences of these four were analyzed. Tintinnopsis kiaochowensis Yin, 1956 is characterized by having an irregular collar with spiral turns and an obconical-shaped bowl. Tintinnopsis orientalis Kofoid and Campbell, 1929 is characterized by the inverted bell-shaped lorica with size of 121-140×86-94 ㎛. Tintinnopsis parvula Jörgensen, 1912 is characterized by its narrower collar than bowl and acute angle of the bowl (39-75°). The recorded species, Antetintinnopsis gracilis (Kofoid and Campbell, 1929) Wang et al., 2021 is characterized by a cylindrical collar narrower than the bowl width and with a size of 98-131×37-46 ㎛.
