Folliculina ? sp.
( Figure 6 View Figure 6 )
Several individuals were observed and impregnated, but no cells with lorica have been found (really not present?). Since the genus identification depends largely on the shape or structure of the lorica, the definition of the genus is, therefore, questionable.
Description
Body shape in vivo as shown in Figure 6A View Figure 6 . Total length of cell about 250 M m long in vivo, shape relatively constant (not very sensitive to disturbance); two ear-shaped wings wide and relatively long (about 120 M m in length), generally transparent except the border area where membranelles arranged ( Figure 6A, B View Figure 6 ). Cytoplasm colourless, but mostly dark grey to black due to numerous food vacuoles (with algae or diatoms) and lipid granules, especially under lower magnification. Macronucleus globular, about 30 M m across with many large nucleoli ( Figure 6C View Figure 6 ).
This organism seems to be a typical benthic form: always using its caudal area to attach to surfaces such as debris.
About 110 somatic kineties, which are typical of folliculinids, consisting of densely arranged dikinetids, each with ca 7 M m long cilia. Membranelles along margin of two wings, extending into deep buccal cavity ( Figure 6C View Figure 6 , arrowheads). Paroral membrane mostly multi-rowed with irregularly arranged basal bodies, parallel to adoral zone ( Figure 6C View Figure 6 , arrow).
