“…All occurrences of the three species of Hastigerinoides (i.e., H. clavata, H. atlanticus and H. alexanderi) are restricted in the Western Hemisphere. The occurrences of Hastigerinoides from the United States Western Interior by Frerichs and others (1977), Frerichs (1979) and Frerichs and Dring (1981) should be referred to Eohastigerinella due to the presence of bulbous projections at the edge of the radially elongate chambers.…”

The Late Cretaceous (Coniacian-Santonian) planktonic foraminiferal genus Hastigerinoides is emended. A new species, H. atlanticus nov. sp., is proposed for the tests with one or rarely two last-formed chambers that are strongly radially elongate and distally tapering in the final whorl. Hastigerinoides consists of three phylogenetically related species: H. clavata (Brönnimann, 1952), H. atlanticus nov. sp., and H. alexanderi (Cushman, 1931). This genus evolved from Globigerinelloides escheri, a Coniacian-middle Campanian, globular-to suglobular-chambered species.
