In addition to Loeblichella carteri, designated here as the type species, Loeblichella hessi (Pessagno) of Kassab (1976) can also be assigned to the present new genus.
Stratigraphical Range. Both Loeblichella carteri Kassab and Loeblichella hessi (Pessagno) of Kassab, which are assigned to Kassabella n. gen., were recorded from the Upper Cretaceous succession of northern Iraq. The former species occurs in the middle and upper Maastrichtian portions of the Shiranish and Tanjero Formations (Globotruncana gansseri Subzone-Abathornphalus mayaroensis Subzone). Similarly, L . hessi was found in the lower and middle Maastrichtian of the Shiranish Formation (Globotruncana area Subzone-Globotruncana gansseri Subzone), (Kassab, 1976). Also, this species was recorded from the upper Campanian-lower Maastrichtian sequence of Iraq (Kassab, written communication). Accordingly, the stratigraphical range of Kassabella is late Campanian late Maastrichtian.
