Original Description

Test free, calcareous, trochospiral, substar-shaped periphery rounded, lobulate; wall comparatively smooth opaque punctate minutely hispid; initial chambers small globose forming a whorl of three or four chambers followed by an outer whorl of cylindrical chambers gradually increasing in length, diameter uniform, the end of each chamber broadly sym met rically rounded; sutures depressed, radiate, aperture extra-umbilical umbilical. 

Holotype (fig. 10) 0.684 x 0.50mm.

Extra details from original publication
This species lacks evidence of spines at the end of the long cylindrical chambers with rounded ends. The shape of last three formed chambers suggests relationship with Globigerina digitata Brady, 1879, type species of genus Beella Banner and Blow, 1960, a species which seems to be a variable taxon. The present one is more sharply defined.
