DescriptionTest shape elongate, nearly straight to slightly curved, strongly nodular, barely tapering, or successive chambers are of equal diameter, except the proloculus which is often largest. Length of test fragments 2–4 mm, the largest 8 mm; test width 0.15–0.25 mm. Chambers pear-shaped, rectilinearly arranged, embracement minimal; chambers attached at the very end of a long apertural neck; number of chambers unknown, the largest fragment has 11 chambers. Proloculus often larger than later chambers. Sutures horizontal. Aperture radial, central and protruding, at the end of a long neck, with up to 12 symmetrical tines, that are fused in center. Surface smooth, except for short longitudinal costae extending for about one third to half of the upper part of the apertural neck; initial end pointed or with long spine. Secondary surface laminations absent. Wall transparent of medium thickness, finely perforated.
RemarksThe 29 examined specimens were all fragments, of which four had a proloculus. The top of the aperture is commonly damaged, exposing a circular, crenulated opening.
