Tropidophora zanguebarica ( Petit, 1850) View in CoL

Cyclostoma zanguebarica: Petit 1850: 53 , pl. 3, fig. 5 (Ile de Zanzibar; 10–12 × 10–12 mm).

Recorded from all three stations on Cabo Delgado, with a general coastal distribution from Kenya to Mozambique. Its relations with T. letourneuxi View in CoL (Ancey in Bourguignat, 1887) should be re-evaluated (see remarks in Rowson 2007: 432). I prefer to use the earlier name here since variability of the shells from Cabo Delgado allows the application of both names. Resembles a small T. insularis View in CoL but, unlike that species, co-occurs with T. ligata . Possibly just a coastal variation of T. insularis View in CoL with size variability from 10.5×10.5 to 13.0×12.0 mm at a single locality.
