Diagnosis.
The new species is nearly indistinguishable externally from
S. asantesana
sp. nov.
, but it is larger (wingspan 14.0 mm vs to 9.2–11.0 mm) and has a more contrasting creamy-white subcostal pattern. The male genitalia are recognized by a combination of the valva far exceeding the top of uncus and a short sacculus. They are most similar to those of
S. natalensis
sp. nov.
, from which they can be distinguished by their shorter tegumen, stronger curved valva, and broader vincular process.
Description. Adult
(
Fig. 45
). Wingspan 14.0 mm. Head, thorax and tegulae covered with brown grey-tipped scales, frons light grey; labial palpus upcurved, palpomere 2 light grey to white, mottled with brown on lower surface, palpomere 3 light grey with diffuse medial and subapical rings; scape brown with greyish-white scales distally, flagellum brown, white-ringed; forewing covered with grey brown-tipped scales, diffuse creamy-white narrow longitudinal pattern under costal margin from base to about 2/3–3/4 length, indistinct brown spot at base under costal margin, diffuse black spots on 1/3 and 2/3 on mid-width, folds slightly mixed with light brown; cilia grey, black-tipped; hindwing and cilia light grey.
Male genitalia
(
Fig. 116
). Uncus twice as long as broad, gradually narrowed apically, posterior margin rounded; gnathos short, weakly curved, culcitula well developed, elongated; tegumen elongated, anterior emargination extending to 1/4 length; valva broad at base, then nearly uniform in width, weakly narrowed in middle, gradually curved, extending far beyond top of uncus; sacculus slightly broader than valva in middle, about 1/8 length of valva, narrowed distally, subrectangular with distinct posterolateral corner, apex with pointed inward-curved tip, separated from valva by large triangular gap; vincular processes slightly shorter than sacculus, broad at base, distally very narrow, outwardly curved, separated from sacculus by broad gap; vinculum slightly broader than long, medial incision deep, triangular; saccus slender, evenly narrowed towards weakly rounded apex, extending slightly beyond top of pedunculus; distal portion of phallus straight, apex rounded with distinct, weakly curved hook, caecum moderately swollen, about 1/3 length of distal portion of phallus.

at the TMSA, who collected the
holotype
of new species.
