Original Description

Test calcareous, finely perforate with fine pustules, dextral, with two whorls, in the last with five demi-arched chambers, in the first globose. Outline lobate. Wide peripheral band, bordered by two distinct pustulate keels. Dorsal side flat, chambers on the ventral side distinctly elongated with sutures deeply depressed, moderately bent to radial. Primary aperture umbilical-extraumbilical, slitlike, without porticus. Umbilicus deep and relatively large

Diameter 0.45 mm, height 0.15 mm; at the last chamber 0.25 mm.

Extra details from original publication
Remarks: We consider this species as predecessor of Archaeoglobitruncana kefiana (Salaj and Maamouri). We observe at the second chamber of the last whorl of the described species at the elongated chamber an indication of spine, which is distinctly developed in primitive specimens of Archaeoglobitruncana kefiana (pl. 1, figs. 1, 2). According to morphology of the test the newly described planktonic species was living in the second depth zone.
