Extra details from original publication
Remarks:The new subgenus Hastigerinoides displays affinities to the Middle Eocene genus Hantkenina (Aragonella), and to the Cretaceous—Recent genus Hastigerinella. It differs from the stellate subgenus Aragonella by the elongate chambers which are subglobular at the base and uniformly tapering toward pointed outer ends. Spines of i type, which are separated from the chambers proper, are not developed in Hastigerinoides. Hastigerinella Cushman (1948. p. 324) is defined by elongate, club-shaped adult chambers, with spines limited to the outer ends. The adult chambers of Hastigerinoides, on the other hand, are pointed, not club-shaped, at the outer end. The difference in the shape of the adult chambers is considered to justify the splitting of the genus Hastigerinella Cushman into Hastigerinella, s. s., with club-shaped adult chambers, and Hastigerinoides n. subgen. with pointed adult chambers.

Occurrence: Upper Cretaceous, Trinidad, B. W. I. Upper Cretaceous, Austin chalk, Texas.
