Description

Test shape elongate to pyriform, nearly straight, short, and somewhat nodular; slightly tapering; initial end rounded. Length of test 0.5–1.5 mm, largest specimen 2.4 mm; test width 0.3–0.8 mm. Chambers sub-globular, diameter increasing rapidly as added, rectilinearly arranged, sometimes in an irregular line; chambers usually strongly embracing; number of chambers 4–6. Sutures horizontal to somewhat irregularly slanted. Aperture radial, central, and slightly raised; radial tines up to 15 of different length, not fused; symmetrically arranged around a central opening. Surface smooth and secondary surface laminations absent. Wall finely perforated and thick.

Remarks

Variation within this species has been noted as varieties A and B (Eiland & Guðmundsson 2004): variety A has embracing rectilinear chambers, where the height of the last chamber may constitute more than half of the test length; whereas the B variety has less embracing chambers, with irregularly slanted sutures. Frequent intermediate forms render distinction between these varieties rather arbitrary. Available material of this species comprised 717 specimens. Diameter of proloculus varies between 0.25–0.40 mm.
