Description: Test stout, straight to slightly arcuate. Chambers subglobular to slightly pyriform. Chamber arrangement rectilinier, often slightly arcuate; successive chambers embrace about a quarter of the previous one, resulting in a nodular shape; number of chambers up to seven. Megalospheres have a short basal spine or knob. Aperture radial, protruding and central. Surface smooth, but a few specimens the base of the chambers have numerous faint and short longitudinal and irregular striations, somtimes associated with faintly granular or even spinous surface. Wall finely perforated, except the apertural face. Sutures horizontal and flush, visible as a faint irregular line. Length of the largest specimen is 9 mm, but most are around 5 mm. About 570 specimens were picked from 119 of the 1031 Bioice samples that were checked for forams.
Diagnosis: Differs from Nodosaria cf. N. farcimen, in being much larger, with more globular and inflated chambers. Most of the specimens have a smooth surface, although the chamber base in occasional specimens of N.subsoluta has finely granular to slightly hispid surface. Differs from Nodosaria cf. N subsoluta in that the pores are much smaller, barely visible in stereo microscope.
