Original Description

"Test small, oval, longer than broad, biconvex, nearly bilaterally symmetrical. Periphery sub-acute, broadly rounded, lobate. Dorsal side flat or slightly convex, showing all the chambers. Ventral side completely involute, umbilicate. Chambers distinct, inflated, globose, somewhat overlapping, about 6 in the adult whorl, rather rapidly increasing in size as added; last 2 chambers occupy more that half of the test. Sutures distinct, depressed, somewhat curved on the dorsal side, radial on the ventral. Surface smooth, shiny. Wall calcareous, very finally perforate, built of radially arranged crystals of calcite. Aperture an elongate slit at the base of the last chamber of the outer whorl extending from the periphery to the umbilicus with a narrow lip. Length of figured specimen 0.26 mm; breadth 0.21 mm; thickness 0.14mm."

Etymology:

Extra details from original publication
Differences. -This species bears a strong resemblance to Anomalina luxorensis Nakkady. That author, after comparing his specimens with this form, remarked '...the true luxorensis has a more evolute coiling and have invariably six-seven chambers in the last whorl.. . ' (personal communication) . Topotype specimens (obtained from the author) of Anomalina luxorensis show that the aperture extends to the ventral side towards the umbilicus. The chambers of Globanomalina ovalis increase comparatively more rapidly.
