Figure 10. Adeonella flabellata sp. nov. Holotype. Mana 20–40 m, Adriatic Sea. Recent. (A) Zooid from near the growing edge. Note the absence of avicularia and the similar secondary orifice and ascopore. Scale bar: 200 µm. (B) Primary orifice with straight proximal border with large U-shaped sinus. Scale bar: 50 µm. (C) Some diamond-shaped zooids with developing frontal tubercles. Scale bar: 200 µm. (D) Zooids from the growing margin, one with peristomial wings converging to form the orificial bridge. Scale bar: 200 µm. (E) Lateral margin of the main colony blade, formed by large zooids, less rhomboidal than the others. Scale bar: 500 µm. (F) Zooids from the margin of a narrow notch in the colony blade. Note the small proximalinward directed avicularia associated with the peristomial bridge. Scale bar: 200 µm. (G) Basal portion of the colony showing the downward increase in secondary calcification and the formation of small prominent frontal avicularia on marginal zooids. Scale bar: 500 µm. (H) Colony margin with kenozooids filling interzooidal spaces. Scale bar: 500 µm.
