Original Description

"Test subcircular, flat dorsally, strongly convex on the ventral side, single-keeled; the chambers increase slightly in size, are curved and overlapping, as in Globotruncana rosetta (Carsey) subsp. rosetta (Carsey) (Globigerina rosetta, 1926). They are strongly convex ventrally, flat andeven concave dorsally. The sutural elevations are thin, well defined and sharply raised. The ventral convexity of the chambers can be so strong as to give in typical specimens a trunco-conical profile (side wall nearly at right angles with the roof of the chambes)."

Size:
Dimensions of holotype: Width 0.89 x 0.86 mm.; thickness, 0.44 mm.

Etymology:
named after Viktor Petters,Head of Paleontological Laboratory of the International Petroleum (Colombia), Limited.
