Original Description
Test low trochoid, asymmetrical, with flattened spiral side and strongly convex, conical umbilical side; with 2 whorls and 4 to 4.5 falcate, almost uniform in size chambers in the last whorl. Test outline rounded, even; on the spiral side chambers falcate, with smooth, evenly perforate surface without spines. Pores on chambers of the early whorl large, on chambers of the last whorl medium-sized, distributed uniformly across the surface except for the keels. Septal sutures formed by keels extending to spiral side, straight, falcate, strongly tuberous, significantly raised above surface of chambers. Chambers on umbilical side trapezoidal, separated by straight or slightly beveled, depressed sutures framed by episeptal bead-like buttresses grading into tuberous epiumbilical overgrowths or epiumbilical buttresses. Umbilical area medium-sized, occupies a half of test diameter. Early chambers of the last whorl slightly spinose, spines are oriented irregularly, 2 last chambers smooth; chambers are uniformly covered with pores of slightly lesser size than on the spiral side. Test periphery wide, somewhat beveled to umbilical side, with one tuberous or bead-like massive keel offset to spiral side. Aperture umbilical, protected by a system of spirally overlapping tegilla with openings.

Size: holotype no. 4898/4: diameter, 0.40; thickness, 0.27.

Etymology: derived from Greek Aeolus, the ruler of the winds in Greek mythology.

Extra details from original publication
Comparison. The species differs from Globotruncanita (Elevatotruncana) andori (de Klasz) in a lesser number of chambers in the last whorl (4⎯4.5 against 5⎯6), a massive tuberous-bead-like but not thin even keel, and in strongly raised septal buttresses on spiral side.

Distribution and age. Upper Campanian, Moni Formation in southern Cyprus.
