Diagnosis.

The new species is externally similar to Aphanostola rooiklipella sp. n. and Aphanostola melliferae sp. n. but differs in genitalia. The male genitalia are well defined by the phallus bearing seven to eight large cornuti in combination with a long saccus and other details. The female genitalia remotely resemble those of Aphanostola morogorensis sp. n., but differ in having a distinctly longer antrum and a narrow, rounded signum.

Description.

Adult (Figs 28-30 View Figures 22–39 ). Wingspan 7.1-7.3 mm. Head, thorax and tegulae grey, labial palpus weakly up-curved, light brown with narrow white ring before apex, scape light brown, other segments light brown with narrow whitish basal ring, antenna finely ciliated and very thick in male, moderately thick in female; forewing light grey, rarely covered with brown-tipped scales mainly along margins, costal margin brown from base to ¼, two brown spots in middle, diffuse brown dash in fold, cilia grey, brown-tipped; hindwing grey.

Variation. Black pattern along margins of forewing varies from grey to nearly black.

Male genitalia (Figs 57 View Figures 53–58 , 58 View Figures 53–58 ). Uncus twice as broad as long, posterior margin with short medial emargination; gnathos curved at base, then straight, gradually narrowing towards pointed apex; tegumen gradually narrowing distally, anterior margin with deep rounded emargination; basal half of valva moderately broad, distal half strongly constricted at base, then weakly inflated, apex rounded; sacculus short triangular, merged with the thorn on the inner margin of valva; vinculum moderately broad, posterior margin with short, broad, triangular medial projections, medial emargination deep and narrow; saccus broad at base, distal portion narrow, tapered apically, far exceeding beyond apex of pedunculus; phallus prolonged, tapered apically, with seven to eight big cornuti, which differ in length, basal projection absent.

Female genitalia (Figs 78 View Figures 77–79 , 79 View Figures 77–79 , 79a View Figures 77–79 ). Segment VIII distinctly longer than broad, evenly sclerotized; apophyses anteriores twice as long as segment VIII and half of apophyses posteriors; antrum long, tubular, strongly edged; sub-ostial sclerite rounded; ductus bursae long, narrow, papillated before antrum; ductus bursae sub-ovate; signum a prolonged sclerite densely covered with teeth.

Etymology.

The name refers to the obviously wide distribution of the species in Africa.

Distribution.

Namibia, Kenya.

Biology.

The larva feeds on Acacia mellifera (M. Vahl) Benth. ( Fabaceae) in Kenya ( Agassiz and Bidzilya 2016). The adults were observed in late August-early September, then in November-January and in March.
