Cyathopoma diegoense Fischer-Piette, Blanc & Vukadinovic, 1974 View in CoL

Fig. 3 View Figs 3–14

Cyathopoma diegoense: Fischer-Piette, Blanc & Vukadinovic 1974: 467 View in CoL , figs 2–4 (Cap Diego, northern Madagascar; c. 2× 3 mm).

A single shell without an operculum, collected on Cabo Delgado, is very similar to the voucher specimen described and illustrated by Emberton (2003: 30–31, fig. 40) from the type locality. The photograph of the shell from Cabo Delgado matches the photograph of the shell from Cap Diego almost exactly when superimposed at 113% magnification. The characteristic sculpture of the spiral cords with the gap on the whorl shoulder (“missing” cord below the suture) and the minute dense axial striation between the spiral cords also can be observed on both shells. Cyathopoma azaniense Verdcourt, 1978 View in CoL from Kenya is smaller (1.4×2.0 mm) and does not have the characteristic gap between the suture and the first spiral cord on the following whorl .

The original description of C. diegoense was based on a single adult specimen “environ” (circa) 2 mm high and 3 mm wide. The same size was repeated in comparison with C. artatum Sykes, 1897 on the same page just below the description. However, the figure of the holotype on the same page has a 0.88 h/w ratio, which clearly does not match the proportions stated in the description. Emberton (2003) did not give any explanation for his decision to include the 2.1 mm high and 2.0 mm wide C. duboisi Fischer-Piette, Blanc, Blanc & Salvat, 1993 , as well as his 1.9 mm high and 2.9 wide “voucher specimen” in the range of variation of C. diegoense . Thus, the specimen from Cabo Delgado is very likely C. diegoense sensu Emberton, 2003 but the extent of the name diegoense is doubtful.
