Original Description
Diagnosis. - The test is small, the dorsal side flat, or gently convex. In the last whorl are 4½-5 chambers subspherical or subangular in the axial part. Aperture at the base of the last chamber.
Description. - The test is coiled in a low trochospire, the dorsal side is flat or gently convex; the ventral convex. In the last of the 2½ whorls consists of 4½-5 slowly enlarging chambers. The equatorial profile is subcircular, the periphery is lobate; the axial periphery is oval to subangular. Sutures are depressed; curved on the spiral side, straight radial on the ventral. The umbilicus is small, deep. The aperture on the base of the last chamber is interiomarginal, umbilical-extraumbilical. 

Size: Size: diameter 0.2-0.3 mm., height 0.12-0.16 mm.

Extra details from original publication
"Carpathian forms are identical with the Trinidad forms described by H. M. Bolli ( 1957, loc. cit.) as Globorotalia spinuloinflata (Bandy) [Globigerina spinuloinflata, 1949]. The holotype of this species is characterized by rounded chamber peripheries, and in this it differs from the species desctibed. Its test morphology is very similar to Turborotalia (Acarinina) crassata densa (Cushman) [Pulvinulina crassata var. densa, 1925] to which it is most likely a synonym (cf. W. A. Berggren, 1960, Stockholm Contr. Geol., vol. 6, no. 5, p. 107; Berggren, 1966, Voprosy Mikropal., no. 10, p. 325; 0. L. Bandy, 1964, Micropaleontology, vol. 10, no. I , p. 6; and E. A. Pessagno, 1961, Micropaleontology, vol. 7, no. 3, p. 356). Turborotalia (Acarinina) vicespinuloinflata Samuel is the ancestral form of Globorotalia pseudospinulosa Samuel.
