22. Subulina octona (Bruguiere, 1789)

Bulimus octona Bruguière 1789: 325

Notes.

The geographical origin of this species is unknown. Gerlach (2006b) notes it has been found as a subfossil on Aldabra but Griffiths and Florens (2006) suggest it is originally Neotropical. Verdcourt (in litt. 2006) noted that he knew of no material of Subulina octona from East Africa so it is possible the species is spreading. The date of authorship follows Bank and Menkhorst (2008).
