Miliolana Miliolana is a subclass established by Saidova, 1981 that comprises porcelaneous members of the Miliolata from the Cornuspirida, Miliolida with agglutinated forms removed to the Miliamminana, and Soritida. Included are both free and attached ...

Miliamminana Miliamminana is a subclass of miliolates established by Mikhalevich, 1980 that combines two groups of foraminifers with agglutinated tests. They are the Rzehakinidae which previously were included in the Texulariina in the Treatise on Inverteb ...

Mikhalevich, 1980) based on similarities of their tests. Previously the Rzehakinidae were included in the Textulariina (Loeblich and Tappan, 1964) based on test wall composition rather than test form. The meaning of Miliolida is retained. The Miliolana are variable in form. All are porceleneous and iperphorate, some incorporating foreign material; some are attached, others free. Includes the Milliolidae which have two tubular chambers per whorl, the multichambered Sorititdae and the mostly prolate

Alveolinidae Alveolinidae is a family of spheroidal to fusiform milioline foraminifera with multiple apertures and complex interiors in which chambers are subdivided into chamberlets and subfloors interconnected by passageways. As with all Miliolina, the te ...

. The Rzehakinidae (Miliamminana) resemble the Miliolidae in overall form but differ in composition.
