Diagnosis
Shell as in Af. inhluzaniensis inhluzaniensis , but baso-columellar denticle present as two smaller, unequally sized denticles, the larger of which is somewhat pointed with the smaller one lying to its right; the latter, though sometimes very small and hard to see through the aperture, is usually evident externally by transparency; palatal lamella prominent, but slender, strongly angled upwards, its crest only slightly thickened.
Etymology
From the Greek leptos (λεπτός): thin, slender, and the Latin lamina, diminutive of lamella: a small plate or blade; with reference to the narrow palatal lamella.

Distribution and conservation
Endemic to eastern South Africa ( Fig. 5 View Fig ), occurring in the coastal hinterland of KwaZulu-Natal and E. Cape, from Zululand (Hluhluwe) to East London, from sea level to 460 m a.s.l.; in leaf-litter of coastal and scarp forests. Not of conservation concern.
Remarks
Afrodonta inhluzaniensis leptolamellaris subsp. nov. is clearly close to the nominotypical subspecies. However, its geographical separation from the latter, together with slight but consistent differences in apertural characters indicate that it merits recognition as an entity distinct therefrom.
