Description

Test shape elongate, slightly curved, sometimes straight, usually moderately nodular, rarely strongly nodular, megalospheres slightly tapering, with round initial end; evenly tapering to a pointed end in microspheres. Length of test usually 3–6 mm, the largest nearly 10 mm; test width 0.6–1 mm. Chambers subglobular, rarely pear-shaped. Chamber arrangement rectilinear, chamber embracement usually moderate; number of chambers 4–8 in megalospheres, up to 16 in microspheres. Sutures horizontal. Aperture radial, central, slightly raised or protruding; radial tines up to 15, symmetrically arranged, usually fused in center (Fig. 12D), sometimes partly fused (Fig. 12E). Initial end with a short spine or thick knob. Secondary surface laminations absent, wall finely perforated and thick.

Remarks

Twelve microspheres were found among the 499 examined specimens. Diameter of proloculus in megalospheres is 0.6–1.0 mm, and <0.03 mm in the microsphere.
