Table 1 Morphometric data of Tintinnopsis hemispiralis, T. kiaochowensis, and T. uruguayensis (measurements in μm). Lorica data are based on live specimens, and other data are based on protargol-stained specimens

From: Three redescriptions in Tintinnopsis (Protista: Ciliophora: Tintinnina) from coastal waters of China, with cytology and phylogenetic analyses based on ribosomal RNA genes
