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.

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.
