Quadrulella madibai Kosakyan et al, 2016
Description: Test ovoid or pyriform, slightly elongated, with a rounded posterior end, laterally compressed towards the aperture. Test colourless, composed of square plates, regularly arranged in rows. The plates are smaller near the aperture (5-6 µm) then gradually become larger (9-11 µm) toward the posterior end of the test. Aperture strongly curved and bordered by a thin organic lip.
Dimensions: L = 83-91 µm, B = 37-45 µm. Aperture 21-23 µm wide (n=5).
Ecology: Peatland in a landscape of upland grassland in the Welgevonden Game Park, South Africa.
Remarks: This species was named to honour Nelson Mandela, the South African revolutionary and later president, who was called Madiba by his friends in reference to the name of his clan.
