Species Gorbachikella grandiapertura Boudagher-Fadel et al. 1995

Discussion / Comments:

Boudagher-Fadel et al. (1997):
Remarks: G. grandiapertura has a very high and broad axio-intraumbilical aperture, five chambers in the first whorl and four in each subsequent whorl, and a high spiral side (d/t = 0.29 approx.). As we have not seen actual specimens of G. compressa, and as the type specimen was inadequately figured (there was no umbilical view), we cannot be sure of its taxonomy and have only doubtfully placed it here. G. spiralis, published in the same paper by Maamouri and Salaj, is, however, clearly synonymous.
