Digitivalva kenyacola spec. nov.

Holotype: ♂, “Coll. Museum Tervuren, Kenya: Taita Hills, 26/06/1998 (I3), Mbololo Forest Edge , [leg.] U. Dall’Asta;” “ RMCA ENT 000003258 ;” “Gen. präp. [genitalia slide] Gaedike Nr. 8029;” “Holotypus Digitivalva kenyacola sp. n. det. R. Gaedike 2014;” RMCA.

Paratype: 1 ♀, same location, but 30/06/1998 (F3); “ RMCA ENT 000003259 ;” “Gen. präp. [genitalia slide] Gaedike Nr. 8028;” “Paratypus Digitivalva kenyacola sp. n. det. R. Gaedike 2014;” RMCA .

Derivatio nominis: Named after the country in which the types were found.

Diagnosis ( Fig. 1 ): Wingspan 10 mm. Head white, scales around insertion of antennae pale grey, in the neck somewhat erected. Labial palpus oblique directed upwards, whitish, with pale scales outside on apex of the first two segments, third segment minute, pointed. Scape of antenna on underside white, on upperside pale, flagellum ringed. Thorax and tegulae white, tegulae basally with paler scales. Forewing ground-colour white with a pattern of grey and brown scales. On dorsum at 1/4 a dark brown, nearly square patch, reaching to cell; at 1/2 an indication of a band from costa to dorsum, first half darker brown than second half. On costa from base to 1/2 some short and thin dark brown lines. Fringe with two dark brown scale-lines. The entire area more or less overlaid with pale and brown scales. Hindwing grey.

Male genitalia ( Figs 7–9 ): Uncus short, truncated, tegumen laterally narrow, ventrally nearly triangular, with long saccus, narrower to rounded tip; valva with more or less rounded basal part, costal arm short, with rounded tip; phallus as long as vinculum + saccus, broader than saccus, nearly straight.

Female genitalia ( Fig. 10 ): Pads of lamella postvaginalis broad, with numerous long bristles; ostium with broad, more strongly sclerotized ring, ductus bursae without stronger sclerotization, apical edge of segment VIII slightly invaginated.

Remarks: Superficially characterized by the square dark brown patch on dorsum of forewing and the two dark brown scale-lines on fringe. Male genitalia similar to D. gelida (MEYRICK, 1921) , but saccus narrower and longer, costal arm of valva short with rounded tip and phallus straight.
