Subspecies Praehedbergella tuschepsensis grigelisi Banner & Desai 1988


Discussion / Comments:
Boudagher-Fadel et al. (1997):
Remarks: P. tuschepsensis grigelisi has five chambers in the first whorl, reducing from four and a half to four in the final whorl. The final chambers are very slightly depressed (h/L = 0.92 approx.). The umbilicus is small (u/uh = 0.19 approx.) The aperture is a narrow slit, extending from the umbilicus to the periphery and is furnished with a porticus. The spiral side is slightly convex. The revision of the nature of this species shows us that P. tuschepsensis grigelisi differs from P. tuschepsensis s.s in possessing higher chambers, a slightly more convex spiral side and a narrower umbilicus.
