Olladiscoaster molae Varol & Bowman, 2024
Hexagonal stellate species of Olladiscoaster have diamond-shaped segments with quasi-arms. The tips of the segments are often pointed. On the distal side, the distinct wind-mill-like sutural ridges are created by the deep cavities. The sutural ridges are raised towards the centre and capped by kite-shaped distal covers. The distinct proximal ridges with a petaloid knob decorate the bulged proximal side. At the side view, Olladiscoaster molae resembles a bouquet.
From the Latin molae, mill – refers to its wind-mill-like appearance.
Maximum diameter: 6.79 µm, Maximum height: 4.67 µm; Diameter of the central area: 4.30 µm, Diameter of the proximal knob: 3.20 µm, Height of the proximal knob: 1.25 µm, Length of the quasi-arm: 1.24 µm, (measurements from bright field micrograph).
Olladiscoaster molae differs from all other Olladiscoaster species by its windmill-like appearance.
