Type material.

Holotype ♀, [South Africa] Pretoria, 1.ii.1951 ( Vári) (gen. slide 8/15, O. Bidzilya) (TMSA). Paratypes: 1 ♂, same data as holotype but 19.x.1951 (gen. slide 6/15, O. Bidzilya); 1 ♂, same data but 18.i.1950 (gen. slide 8332); 1 ♂, Pretoria N, 26.i.1954 ( Vári) (gen. slide 4/15, O. Bidzilya); 1 ♀, Pretoria N, 27.i.1951 (gen. slide 11/15, O. Bidzilya) (all TMSA).

Diagnosis.

The new species is externally very similar to Aphanostola emarginata sp. n. in having brown forewing, but the forewing is densely black irrorated. The male genitalia are defined by the very short basal projection of the phallus. The elongated narrow subostial sclerite and the narrow signum are characteristic for the female genitalia.

Description.

Adult (Fig. 11 ). Wingspan 7.3-8.1 mm. Head, thorax and tegulae covered with grey brown-tipped scales, labial palpus brown, segment two mixed with grey on inner side, segment three with white medial belt and white apex, antenna in male thicker than antenna in female, finely ciliated, scape brown, flagellum with alternated brown and whitish rings; forewing brown, costal margin mottled with black, diffuse black spot at 2/3 on both margins, black dot in fold, paired black spots in cell, apical ¼ scattered with black, cilia grey, black tipped. Hindwing light grey.

Variation. Some specimens with blackish dorsal margin of forewing.

Male genitalia (Fig. 48 ). Uncus broader than long, posterior margin distinctly emarginated; gnathos long, gradually curved in basal half, weakly broadened before pointed tip; tegumen sub-trapezoidal, anterior margin twice as long as posterior margin, anteromedial emargination broad, moderately deep; basal half of valva straight, inner margin with distinct thorn just after sacculus, distal half narrow, densely haired, apex rounded; sacculus stout, triangular, broader than valva; vinculum moderately broad, medial projections short, rounded, medial incision very narrow; saccus basally broad, then tapered, far exceeding beyond apex of pedunculus; phallus weakly narrowed apically, basal projection narrow, nearly reaching tip of phallus.

Female genitalia (Fig. 81 ). Segment VIII slightly longer than broad, evenly sclerotized, apophyses anteriores about 2.5 times longer than segment VIII; antrum funnel-shaped; sub-ostial sclerite sub-ovate with lateral folds; ductus bursae narrow in posterior part, then broadened gradually to broad corpus bursae; signum narrow, elongate.

Etymology.

The species is dedicated to Martin Krüger, Lepidoptera curator in the TMSA, for his continuous help during our work in the collections of the TMSA.

Distribution.

South Africa.

Biology.

The host plant is unknown. The adults were collected in October, January and February.
