Original Description

. Trochospirally ceiled biconvex test, two keeled with 5-6 chambers in the last whorl.

Description. Test free biconvex, with 5-6 chambers in the last whorl. The few last chambers rapidly increase in size. The spiral side slightly convex, smooth. The umbilical side with slightly inflated chambers covered by protuberances. The spiral sutures oblique, distinct, the umbilical sutures radial, depressed. Two keels quite closely spaced. The umbilicus deep, narrow. The aperture interiomarginal, accessory apertures not observed.

Size: holotype: longer diameter 0,554mm, shorter diameter 0,504 mm, thickness 0,352 mm

Extra details from original publication

Derivatio nominis. The species is named to the honour of Dr. J. Klaus, the famous swiss geologist and micropaleontologist.

Remarks . The species does not closely resemble any known species of Praeglobotruncana. To some degree resembles Praeglobotruncana oraviensis Scheibnerová. From this species it differs in having two distinct keels.

Variablity. We have not at our disposal enough material to study the variability. We may say that this species varies in the number of the last whorled chambers and measurements of the test.
