Notes.

The Pemba material matches that from Unguja figured by Rowson (2007) under the name Afroguppya rumrutiensis , and the " Dupontia sp." found on Aldabra ( Gerlach and Griffiths 2002). Although these three populations appear conspecific, the species is not the mainly East African Afroguppya rumrutiensis . The West African Afroguppya solemi de Winter & van Bruggen, 1992 resembles it closely in size and shape, but has obscure spiral sculpture ( de Winter and van Bruggen 1992) whereas these are finely granular. Igor Muratov (pers. comm.; Muratov in press) refers similar material from north-east Mozambique to Microcystina minima , a common species on the Mascarenes (see Griffiths and Florens 2006).
