Diminovula-like Shells

Hi all.

Cate (1973) and Lorenz & Fehse (2009) discuss Diminovula alabaster. I have found typical shells here:

However, upon reinspection of the same lot, I chanced upon some interesting shells, which I would appreciate help with.

(A)This one seems to be an elongated variation of alabaster (6.3mm)

(B)This one appears Margovula-like, but could be alabaster sub-adults (4.9 & 8.6mm respectively):

(C) This one has shape and size that approaches D. coroniola shown on pl. 53, no. 6 of Lorenz & Fehse (2009) (12.5mm):

Thanks for your help in advance!

Hello Wei,

specimen A and the right (8.6 mm) specimen B are D. whitworthi. Specimen C is assigned at the moment to D. alabaster. For the left (4.9 mm) specimen B I do not have any suggestions now (have no literature with me in the office).

Hope could help you a little bit.

Ciao, dirk

B (left) bimaculata
B (right) aurantiomacula
C is a large alabaster (note the fine teeth and narrow aperture)

Thanks for all the suggestions.

B(left, 4.9mm) might be a little small for bimaculata.
