Trochonanina bloyeti Bourguignat, 1889

Fig. 50 Trochonanina bloyeti: Bourguignat 1889: 21 (Near Kondoa, Usambara, north-eastern Tanzania; 7× 15 mm).

A rare eastern African species, with a general distribution from northern Tanzania to central Mozambique. A single shell found inland. Quite similar to the preceding species, differing from it by the wider spaced, stronger axial ribs on the upper side of the more depressed, uniformly coloured shell. The shell illustrated here has lighter spots in places of the damaged periostracum.
