Description: Distinguished by the delicate, loosely coiled test, with five rapidly expanding globular chambers in the last whorl, a highly arched primary aperture and a rimmed secondary aperture at base of last chamber on the spiral side.
Distribution: Duntroonian to Waitakian.
Comment: This taxon includes very rare Globigerina-like forms in the Upper Oligocene. They more resemble aberrant Globigerina than they do the earliest definite Globigerinoides in the Waitakian (Hornibrook 1974).
