Diagnosis

Shell very small, spire distinctly raised, last adult whorl relatively deep, lenticular to almost subglobose; protoconch smooth, at most microscopically shagreened or malleate (diameter ±320 μm); teleoconch texture silky; sculpture comprising simple, very fine and close-set axial riblets of alternating strength; spiral sculpture of fine threads in riblet intervals; parietal region with two well-developed, in-running lamellae; baso-columellar region with a strong, ridge-like denticle; palatal region with 5–8 in-running lamellae, those above periphery weaker; umbilicus relatively narrow. Shell whitish to dark purplishbrown when fresh; diameter up to 1.45 mm.

Material examined

Holotype

SOUTH AFRICA • E. Cape, Grahamstown; prior to 1912; J. Farquhar leg.; NHMUK 1912.3.25.4.  

Paratypes

SOUTH AFRICA – E. Cape • 1 specimen; Grahamstown, Mountain Drive ; prior to 1912; NMSA A9214/T2178   1 specimen; Kowie [Port Alfred]; NHMUK 1937.12.30.2763   2 specimens; Bathurst, Trappes Valley ; NMSA A9619/T615   .

Distribution and conservation

The widest ranging of all aperturally dentate charopid snails in southern Africa ( Fig. 3 View Fig ) Recorded from Grootvadersbosch in W. Cape through much of E. Cape and KwaZulu-Natal, the escarpment of Mpumalanga, and the Soutpansberg and Wolkberg massifs in Limpopo. Ranges beyond South Africa to Mount Vengo (Monte Panga) in the highlands between Zimbabwe and Mozambique ( Connolly 1925), and northward to Malaŵi ( Bruggen & Meredith 1984; Bruggen 2007). An isolated record ( Connolly 1939) from Kimberley (N. Cape) requires confirmation. Lives in leaf-litter of a wide variety of forest and woodland habitats, from the coast to 1800 m a.s.l.. Not of conservation concern.

Remarks

Closest to Af. farquhari   , but that species has fewer palatal lamellae and a weaker baso-columellar denticle, and the last adult whorl is not as deep.
