Original Description
Test small, elongate, tapering, often slightly twisted ; about twice as long as wide, with ratio of length to width varying from 1.5 to 2.56; biserial throughout: 5 to 6 pairs of chambers, last 2 or 3 pairs rather inflated; earlier chambers short. compressed: sutures depressed in the adult between the inflated chambers. flush with the surface in earlier part of the test: sutures almost at right angles to the axis of the test in youth, becoming more slanting in the adult: surface smooth: aperture fairly large, height about twice the width, a narrow delicate collar that projects more on one side than on the other, and on that side slants somewhat across the lower end of the aperture.

Size: Length 0.09 to 0.30 mm.: width at widest point 0.06 to 0.11; thickness at apertural end approximate 1/4 of the length of the test. Holotype is 0.27 mm. long, 0.13 mm. wide and 0.08 mm. thick.

Extra details from original publication
The species which seems closest to tokelauae is Bolivina globulosa Cushman, 1933, from the Recent Pacific, about 12 degrees North and 137 degrees West. Bolivina tokelauae differs, however, in the following respects: 1. The last chambers in B. tokelauae are more equidimensional and bulbous than in B. globulosa. 2. The aperture of B. tokelauae has a definite lip, and is proportionately a somewhat larger aperture. 3. Adults of B. tokelauae has sutures that slant back appreciably: B. globulosa has sutures that slant back only slightly.
