Photomicrographs of the Haikou population of Antetintinnopsis karajacensis comb. nov. in vivo (AF). A, B Lateral views of two representative individuals showing the overall shape of lorica. C Anterior portion of a cell proper, arrow shows the elongated ciliary tuft. D, E Lorica wall with mineral particles. F Pin-shaped tentaculoids (arrow). GJ Photomicrographs of the Beihai population of A. karajacensis comb. nov. from live specimens. G, H Lateral views of different individuals showing variations of lorica shape and size, arrowhead denotes the elongated ciliary tuft. I Cell proper out of the lorica, arrow and arrowhead indicate the elongated cilium of left ciliary field and pin-shaped tentaculoids, respectively. J Portion of cell proper, showing amplification of the particles (arrow) within the cytoplasm. KN Photomicrographs of the Zhoushan population of A. karajacensis comb. nov. from living specimens. K Lateral view showing cell in the lorica. L Details of the surface of lorica. M Fully extended cell, arrow denotes the branched peduncle. N Dorsal view of a cell proper, arrow indicates the bifurcation at the end of the elongated ciliary tuft. Scale bars = 40 μm (A, B, G, H, I, N), 20 μm (K)
