摘要
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.
