Original Description
Test free, trochospiral, planoconvex, umbilicoconvex, with rather wide, deep and open umbilicus, periphery subacute, peripheral outline lobulate; chambers hemispherical, flattened to gently convex and appearing lunate in side view from the spiral side, strongly inflated to subangular on the umbilical side, 4 to 5 in the final whorl, commonly somewhat obliquely overlapping earlier chambers, the forward margin of each chamber protruding slightly above the general level of the spiral side, the posterior margin of the succeeding chamber beginning at a slightly lower level; sutures distinct, strongly curved and slightly depressed on the spiral side, radial and strongly depressed on the umbilical side, wall calcareous, rather coarsely perforate, surface spinose, most strongly on the umbilical side; aperture interiomarginal, extraumbilical-umbilical. a broad arched opening, with a narrow bordering lip present in well preserved specimens.

Size: Hypotypes range from 0.23 to 0.45 mm. in diameter and from 0.15 to 0.33 mm. in thickness.

Etymology: The specific name is from the Greek apanthisma, a plucked flower.

Extra details from original publication

Remarks: Globorotalia apanthesma, new species, differs from G. acuta Toulmin in lacking a peripheral keel, in having a spinose surface, less angular chambers, more convex spiral side, and less ornamented umbihcal shoulder.

Globorotalia angulata (White) differs in being larger, in having fewer chambers and more rapid increase in chamber size and the chambers are more angidar in spiral view, more inflated in umbihcal view, with a more truncate periphery and a more finely spinose surface.
