Kempioconcha cf. obtusa View in CoL auct. non ( Boettger, 1913)

Fig. 21 View Figs 15–25

Pseudoglessula cf. obtusa: Verdcourt 1967: 50–52 View in CoL , fig. 23.

A rare and possibly not previously recognised species. Only a few damaged shells were found at four stations in a 6× 20 km area west of Palma. The size of the shell varies significantly, the largest (8 whorls; subadult) being 40× 20 mm. The same-sized Krapfiella magnifica Preston, 1913 a View in CoL has a spirally sculptured protoconch. Differs from all other large species of Kempioconcha View in CoL by the narrowly conical apex. Apparently the largest species of the genus. Verdcourt (1967: 50–52, fig. 23) most probably illustrated the same species (7 whorls subadult) from the Rondo Plateau in south-western Tanzania and gave the following shell dimensions (26.0–29.5×12.0–15.0 mm) for this species, which he called “ cf. obtusa Boettger View in CoL ” and suspected that it “will prove to be conspecific” with true obtusa Boettger, 1913 View in CoL and obesa Germain, 1916. However, Kempioconcha obtusa ( Boettger, 1913) View in CoL , the largest known species of the genus (32.0× 15.5 mm, with obesa apparently being a synonym), has a noticeably wider, obtuse apex, which is the defining character of that species according to Boettger (1913: 352, pl. 17, fig. 2).
