Redescription. Male ( Fig. 10 ). Head: Beige. Antenna brown, scape beige. Labial palpus ca. 1.8 times diameter of eye, light beige; third segment drooping, nearly concealed by scaling of second segment. Thorax: Dark reddish brown. External surface of fore and mid-legs grey, internal surface pale beige, light rings on tarsi; hind leg beige, tibial pencil ochreous. Wingspan 18.0–19.0 mm. Basal third of forewing upperside black, with strong admixture of reddish; distal two thirds light beige, terminal and tornal area with grey, black and red striae, forming a rounded spot below costa; costal strigulae only faintly indicated. Cilia dark grey and black. Hindwing light grey, sparsely scaled, darker along veins, with anal roll. Abdomen: Light brownish grey, anal tuft beige. Genitalia ( Fig. 26 ) with uncus subtriangular, rounded, setose; socii broad, setose; valva with rather shallow cavity, neck broad, group of spines between caudal edge of sacculus and basal excavation not reaching middle of sacculus; cucullus with spines along ventral edge; phallus short and broad.

Female ( Fig. 19 ). Head and Thorax: Essentially as described for male, but with darker hindwing and lacking anal roll and hairpencil of hind tibia. Abdomen: Genitalia ( Fig. 35 ) with sterigma subtrapezoid with rounded posterior corners; ostium situated close to anterior edge of sterigma, with lateral folds forming a cup round ostium; sterigma with weakly sclerotised central part forming a “window”; inception of ductus seminalis into ductus bursae close to corpus bursae; signa small and broad.

Diagnosis. Externally characterised by the strong admixture of reddish on the thorax and the basal part of forewing upperside, and the dark forewing cilia contrasting with the terminal part of the wing. The male genitalia have a broader neck of valva and a shorter, broader phallus than other Neaspasia . The female genitalia are distinguished by the relatively small signa and small sterigma with large ‘window’.

Distribution. This species is known from the Republic of South Africa and Mozambique.
