Figure 12. Hemigastrostyla szaboi (A–F), Holosticha diademata (G, H, J) and Metaurostylopsis marina (I, K, L) after protargol impregnation. (A) Ventral view, to show the general morphology, arrows mark the macronuclei. (B, C) Detail of anterior portion, to show the frontal and anterior three ventral cirri located in the frontal area (arrows). (D–F) Ventral view of caudal portion, arrowheads in D mark the transverse cirri, while those in E indicate the two fine pre-transverse cirri; arrows in D, E mark the extra cirrus. (G, H) Ventral view of the same specimen, to show the transverse cirri (arrow in G) and the macronuclei (arrows in H). (I) Ventral view of anterior portion, to show the frontoterminal cirri (arrow) and the buccal cirrus (arrowhead). (J) Ventral view of a slender form, arrow marks the transversely arranged anterior end of left marginal row, arrowheads mark the two macronuclei. (K) Ventral view of caudal portion, arrow marks the transverse cirri. (L) Ventral view of anterior portion, to show the short ventral row posterior to the midventral rows (arrow). Scale bars: 50 Mm (A); 30 Mm (G, J); 20 Mm (I).
