Original Description

Test free, planispiral, partially evolute, so that earlier coils may be seen on both sides of the biumbilicate test; chambers numerous; sutures may be limbate; wall calcareous, coarsely perforate; apertnuor peripheral, an arch at the base of the aptertural face of the last-formed chamber, with a distinct lip.

Etymology:

Extra details from original publication

This genus is probably derived from Anomalina d'Orbigny by the loss of the early trochoid stage and the development of a completely planispiral test. The aperture has also become peripheral, losing the ventral extension. Planomalina, n. gen., resembles Palmerinella Bermudez in the presence of the apertural lip, and Planulina in the shape of the chambers and evolute character of the test (such as Planulina ariminensis d'Orbigny) and the position of the aperture, but Planomalina differs from both of these in lacking any trochoid development.
