Type material.

Holotype ♂, [South Africa] RSA, Natal, Mkuzi, [15'sq NW cnr, 27 30'S, 32 05'E], 23-26. Apr. 1982 (Scoble, Laurenson & Kroon) (gen. slide 48/15, O. Bidzilya) ( TMSA).

Diagnosis.

As far as we can judge from the single male, the new species is most similar to Aphanostola kruegeri sp. n. in having brown forewings, but differs in exhibiting a poorly expressed irroration. The male genitalia are well defined by the very deep medial emargination of the posterior margin of the vinculum, a short hump-shaped sacculus and by the absence of the vincular projections.

Description.

Adult (Fig. 31 ). Wingspan 6.0 mm. Head light grey, labial palpus brown, segment two with white upper and inner side, segment three with white medial ring and white apex, antenna in male moderately thick, scape brown, other antennal segments brown, whitish-ringed; thorax and tegulae brown; forewing light brown with dark brown scales particularly along margins and in sub-apical area, cilia grey, brown tipped; hindwing grey.

Male genitalia (Fig. 59 ). Uncus about as broad as long, weakly broadened apically, posterior margin slightly emarginated; gnathos narrow, weakly curved, tapered; tegumen sub-rectangular, anterior margin deeply emarginated; valva broad in basal half, weakly constricted in middle, distal portion outwardly curved and hairy, apex rounded; sacculus short, rounded, hump-shaped; vinculum broad, posterior margin without projections, divided by deep and narrow medial incision into strongly sclerotized rounded lobes, saccus triangular, broad on base, tapered; phallus long and narrow, weakly narrowed apically, without basal projection.

Female. Unknown.

Etymology.

Derived from “emarginatus” (Latin), excised, referring to the excised vinculum in the male genitalia.

Distribution.

South Africa.

Biology.

The host plant is unknown. The holotype was collected in late April.
