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.
