Description: Distinguished by the tiny, smooth, planispirally coiled form with a low arched peripheral aperture.
Comparison: P. micra differs from its predecessor Globanomalina wilcoxensis by being planispirally coiled with more radially elongate chambers.
Distribution: Waipawan?, Mangaorapan to basal Whaingaroan (Globigerina brevis zone of Jenkins).
Comment: A very characteristic Eocene species whose last appearance datum is widely used to recognise a position in the Lower Oligocene.
