Original Description

The test is slightly smaller than Globotruncana (Globotruncana) wiedenmayeri Gandolfi subsp. weidenmayeri Gandolfi, 1955; six of seven chambers are present in the last volution, which increase slightly in size but less than in Globotruncana (Rugoglobigerina) rugosa (Plummer) subsp. rugosa (Plummer) [Globigerina rugosa, 1927]. A discontinuous beaded double keel fringes the shell and becomes somewhat masked by rugosity in the early stages of the last volution. The umbilical cavity is quite large; no apertural lips could be observed through the hard matrix. 

Size:
Dimensions of holotype: Width 0.80 x 0.78 mm.; thickness 0.48 mm.
