| Diagnosis / Definition: | ||||||
|
Boudagher-Fadel et al. (1997): Diagnosis: Test large, about 460-550 µm at its maximum diameter, planispiral, early whorls compressed; eight chambers in the last whorl, slightly inflated, narrow, higher than broad, increasing gradually in size, sutures slightly curved depressed; wall macroperforate with sharp muricae on the early whorls, the macroperforations becoming deep and the rims of these depressions fusing to give a cancellate texture; aperture interiomarginal, equatorial, symmetrical, extending laterally into small umbilici, relict umbilical apertures furnished with thin portici. |

|
Boudagher-Fadel et al. (1997): Remarks: This species differs from A. bentonensis (Morrow) in having a higher number of (narrower) chambers, a muricate test with very concentrated macroperforations. It differs from Alanlordella praebuxtor- (Wonders) in lacking muricocarina on the periphery of the early whorls, and in the much deeper and larger macroperforations. |
