Fig. 1 in Shedding light on the origin of Acanthocystidae: Ricksol blepharistes gen. n., sp. n. (Ricksolidae fam. n., Panacanthocystida, Centroplasthelida), with notes on the evolution of the genera Acanthocystis, Ozanamia gen. n. (Ozanamiidae fam. n.), and "Heterophrys-like organisms"

Fig. 1 Morphology of Ricksol blepharistes gen. n., sp. n. a, b General view of the undis- turbed cell in a Petri dish, IMC. c The cells, squished under a coverslip, DIC. d Single scales detached from the cell depicted in (c). Collage (scales from 3 separate images were com- bined in one view; original raw images are available in Figs. S1, S2, and S3) (PC). e General view of the air-dried spine and plate scales. SEM. f Close-up of the air-dried spine and plate scales (SEM). g Close-up of the single plate scale. SEM. h A crenate margin of the plate scale (SEM). i A fragment of the spine scale from a basal plate end (SEM). Abbreviations: a, axopodia; ar, axial rib; bp, basal plate; g, granules (kinetocysts, extrusomes); hp, hemispherical papillae; m, margin; ps, plate scales; se, conical shaft ending; sh, shaft; ss, spine scales. Scale bars: a–e (a and b are in the same scale to show size variability) 10 µm; f 2 µm; g–i 1 µm
