Original Description
Test free, small, planispiral, involute, biumbilicate, outline deeply lobate, periphery rounded. Chambers spherical in early whorls, becoming radially elongate in last whorl, ovate to cylindrical, five or less commonly six chambers in last whorl, nearly completely embracing previous whorl. Sutures distinct, deeply depressed, radial. Wall calcareous, smooth, finely perforate. Aperture basal, equatorial, a low to high arch embracing previous whorl, up to one-third height of final chamber, with upper margin bordered by a slightly protruding lip.

Size: Greatest diameter of holotype .357 mm; greatest thickness .128 mm.

Etymology: The specific name is from the Latin prolixus, meaning "long, stretched out," in reference to the elongate chambers of this species.

Extra details from original publication
Remarks: This new species resembles Hastigerinella bermudezi Bolli, but differs in the more planispiral rather than trochospiral adult test, and the somewhat smaller size.
