Aegyriana paroliva Song and Wilbert, 2002

( Figures 3A–E View Figure 3 , 12B, C, E, F View Figure 12 )


Body generally less variable (less flexible) than in original population, generally oval in shape with conspicuous snout-like projection on anterior left ( Figure 3A, B View Figure 3 ). Cells in median area distinctly thickened ( Figure 3B View Figure 3 ). Cytoplasm dark grey due to numerous globules and food vacuoles ( Figure 3C View Figure 3 ). Food vacuoles often large (about 5–10 M m across), full of green or reddish algae or flagellates, but not many diatoms ( Figure 3C View Figure 3 ). No contractile vacuoles observed.

Ciliation basically matching original description well, preorally about six to seven kineties arched to left margin of cell with some anterior-most kineties consistently shifted dorsally ( Figure 3D View Figure 3 ). Perioral kineties (oral apparatus) clearly in two groups: right one three-rowed and fragment-like, separated from the single left kinety; all structures consisting of densely arranged dikinetids. On ventral side, general arrangement of kineties similar to that described previously (Song and Wilbert 2002) with all postoral kineties terminating anteriorly at buccal region and forming dominant buccal area ( Figure 3D View Figure 3 ). However, 18– 20 kineties on left posteriorly shortened gradually leftwards ( Figures 3D View Figure 3 , 15E View Figure 15 , arrowheads and arrows). About nine kineties at posterior end ‘‘interrupted’’ by podite and hence forming large glabrous area, on the right of which there are about eight kineties, and ca four on the left ( Figure 3D View Figure 3 ).
