Description

Test shape elongate, cylindrical, straight, barely to moderately nodular and slightly tapering; initial end rounded. Length of test 0.7–1.5 mm, the largest 2.2 mm; test width 0.4–0.5 mm. Chambers subglobular to cylindrical. Chamber arrangement rectilinear, embracement moderate to minimal; number of chambers 4–6 in microsphere, up to 12 in microsphere. Initial 3–5 chambers in microsphere are wound in about half of an evolutive planispiral ( Fig. 14A ). Sutures horizontal. Aperture radial, central and slightly raised; radial tines up to 12, symmetrically arranged and fused in the center. Wall smooth, finely perforated of medium thickness.

Remarks

Available material of this species comprised 371 specimens, of which 9 were microspheres. Diameter of proloculus in megalospheres is 0.15–0.30 mm, and <0.05 mm in microspheres.
