Extra details from original publication
Familia Rotaliidae; subfamilia Globotruncaninae. Cretacico.

Aparentemente este genera es un antecesor de Globotruncana Cushman, del que difiere par ser menos umbilicado y por tener el horde perifirico con una sola quilla. Tambien es parecido a Globorotalia Cushman y a ciertas Valvulinerias comprimidas. Ademas del genotipo pertenece al presente genera Globorotalia marginaculeata Loeblich y Tappan, 1946; Cretacico inferior, Texas."
