Figs 23–30. Zosterodasys transversus, neotype specimens after protargol impregnation. 23, 25 in Taxonomic Revision and Neotypification of Zosterodasys transversus (Kahl, 1928), with Description of a Mirror-Image Doublet (Ciliophora, Phyllopharyngea, Synhymeniida)

Figs 23–30. Zosterodasys transversus, neotype specimens after protargol impregnation. 23, 25 – ventral view of ciliary pattern and oral apparatus of normal specimens; 24 – ventral view of ciliary pattern and oral apparatus of an abnormal specimen having a double cytostome and cyrtos; 26 – dorsal view of ciliary pattern showing synhymenium extending onto dorsal side; 27 – ventral view of the monster whose anterior body portion is shown in (24); 28 – ventrolateral view of a specimen having some breaks in synhymenium (asterisks); 29, 30 – ventral and dorsal views of ciliary pattern in posterior body portion showing that somatic kineties extend meridionally, i.e. do not form a suture or spica. Arrowheads denote slit-like cytopyge. CY – cytopyge, D – diatoms, MA – macronucleus, OA – oral apparatus, PB – pharyngeal basket, SK – somatic kineties, SY – synhymenium. Scale bars: 20 µm (28), 30 µm (23–26, 29, 30), and 50 µm (27).
