Material. One single specimen from the sample PC060615.

Description. Test free, composed of a subspheric proloculus followed by a tube glomospirine or streptospirally coiled, which tends to uncoil and become rectilinear carrying on with the ontogeny. The tube is initially undivided, after some constrictions at irregular distance define the chambers.

Distribution. Cretaceous to Recent ( Kaminski and Gradstein, 2005).
