Holotype in the mobile mount.
Olladiscoaster superbus Varol & Bowman, 2024
Hexagonal stellate species of Olladiscoaster have boomerang-shaped segments with quasi-arms. The shorter sides of segments meet at the centre. On the distal side, the distinct sutural ridges are created by the deep cavities. The sutural ridges are raised towards the centre and capped by boomerang-shaped distal covers. The distinct proximal ridges with a large petaloid knob decorate the bulged proximal side. From the side view, Olladiscoaster superbus resembles a chamber pot.
From the Latin superbus, superb – refers to its magnificent appearance.
Maximum diameter: 8.58 µm, Maximum height: 5.48 µm; Diameter of the central area: 5.27 µm, Diameter of the proximal knob: 6.31 µm, Height of the proximal knob: 2.75 µm, Length of the quasi-arm: 1.65 µm, (measurements from bright field micrograph).
Olladiscoaster superbus differs from other Olladiscoaster species by having slender kite-shaped segments whose longer site forms a quasi-arm and a large petaloid proximal knob.
