CertesellaRalf Meisterfeld and Edward Mitchell
Certesella is a very conspicuous genus which is restricted to the southern hemisphere. It was proposed by Jung (1942) as Penardiella without type designation (Loeblich & Tappan, 1961). Four species, type species: Certesella martiali (Certes, 1889).
Shell flask-shaped, compressed, neck with parallel sides, organic apertural rim. In broad view on each side two pores in depressions connected by an internal tube like in Porosia bigibbosa. Neck with one or two internal organic thickenings and rows or groups of teeth at both sides. Scanning electron microscopy reveals surface to be relatively smooth. Shell transparent, composed of collected euglyphid idiosomes in an unstructured organic cement.
