Achatina randabeli Bourguignat, 1889 View in CoL

Fig. 20 View Figs 15–25

Achatina randabeli: Bourguignat 1889: 84 View in CoL , pl. 5, fig. 6 (Tabora, Ounyanyembé; 55× 28 mm).

A rather uncommon species, previously known only from the type locality in central Tanzania. Found at five stations inland and two station on Cabo Delgado. One of the smaller species of Achatina View in CoL . The largest shell from north-eastern Mozambique is 51× 26 mm. Achatina arctespirata View in CoL (57× 32 mm) described by Bourguignat (1889: 83, pl. 5, fig. 7) from the southern region of Tanganyika is probably a synonym based on a freak specimen. Both species were considered subspecies of the Tanzanian A. craveni Smith, 1881 View in CoL (type: 81× 37 mm) by Bequaert (1950: 50). Differs from all other species of the genus by the narrow-conical apex with straight outlines. Can easily be separated from similar sized species of Limicolaria View in CoL by the strongly truncated columella.
