Figure 1

Caudikeronopsis monilata sp. nov. from life (A, B, E–K) and after protargol impregnation (C, D, L). (A, E) Ventral view of a representative specimen. (B) Cortical granules on the ventral side. (C, D, L) Ventral and dorsal view of the holotype indicating ciliary and nuclear pattern. (F–I) Body variations in lateral and ventral view. (J) Arrows marking dorsal kineties. (K) Ventral view to indicate adoral membranes (arrowheads) and cortical granules (arrows). AZM: adoral zone of membranelles; CC: caudal cirri; DK: dorsal kineties; EM: endoral membrane; FC: frontal cirri; FT: frontoterminal cirri; LMR: left marginal cirral row; Ma: macronuclear nodules; Mi: micronuclei; MP: midventral cirral pairs; PM: paroral membrane; RMR: right marginal cirral row; TC: transverse cirri.
