Species Acarinina nicoli Martin 1943

Diagnosis / Definition:

Tjalsma (1977):
The species is characterized by the low conical umbilical side, the narrow umbilicus and the tangential sutures on the spiral side. There is quite a variation in the degree of the conical angle, in some variants being less sharp than figured in the holotype. Throughout its range it grades into five-chambered forms which are close to Acarinina praepentacamerata (Plate 1, Figures 4-6). The peak abundance of A. nicoli occurs somewhat above that of A. tadjikistanensis djanensis, notably in the top of Core 33. Moreover, it outranges the latter species in the base of Core 32 where it occurs in low frequencies.
