A new genus, Braunella , is proposed for a lineage of serial planktonic Foraminifera of late Campanian-Maastrichtian age. The genus includes two species, B. punctulata (Cushman, 1938) and B. brauni nov. sp., which are characterized mainly by their irregular reticulated test ornamentation. The genus seemingly evolved in the late Campanian from the costate species Heterohelix striata (Ehrenberg, 1840), and became extinct at the Cretaceous/Tertiary boundary
