Galeacornea Stover 1963 (elaterate)


Generic description: Palynomorphs with an ellipsoidal or subhemispherical body, usually longer than high, having on the distal surface one or more large, prominent horns or sheet-like flaps and on the proximal surface a narrow slit-like or elliptical aperture extending the full length of the body or nearly so. The body is encircled by a zona or band that is continuous or interrupted, of constant or variable width, situated equatorially or proximally with respect to the body, and generally lies in a plane. In one species the zona, as seen in lateral view, is arcuate with its projection across the narrow ends of the body arched distally. Body wall consists of a single layer over all or most of the body; proximal portion two-layered in one species. Body smooth or variously ornamented; granulate or spinate in known species. Zona, bands, horns and distal flaps smooth or granular on the surface; solid; generally, with a textured core and a much thinner, homogeneous, untextured superficial layer. The textured and untextured parts do not constitute separate and distinct wall layers such as the sexine-nexine wall layering of many pollen grains. Over-all size less than 100 microns.
