Alucita tanzanica Ustjuzhanin & Kovtunovich  sp. nov.

( Figs 9–11 View Figure ).

Diagnosis. In the external characters of the adults and in the genital structure, A. tanzanica  is similar to A. certifica ( Meyrick 1909)  . In the female genitalia, the new species differs from A. certifica  by the goblet-shaped antrum, by the anterior apophyses which are longer than posterior ones, also by the rounded swelling on the ductus and the distally widened bursa copulatrix; while in A. certifica  the antrum is funnel-shaped, the posterior and anterior apophyses are equal in length, the swelling on the ductus is oval and elongated, the bursa copulatrix is narrow, elongated and not widened basally. In the male genitalia, these species differ by the apically widened uncus and by the long aedeagus which is 1,5 times longer than the entire genitalia in A. tanzanica  , and by the apically narrow uncus and the aedeagus equal in length to the entire genital structure, in A. certifica  .

Description. Adult. Head, thorax and tegulae white. Antenna yellowish-brown. Labial palpus wide at base, narrow to apex, two times bigger than longitudinal eye diameter, brown on external side, white on inner side. Wingspan 9–10 mm (holotype 9 mm). Wing white. Wide pale brown streaks medially and distally on fore and hind wing. Small dark spot of scales on apex of each lobe of fore and hind wing. Fringe on wings with white and yellowish hair-like scales. Hind leg white.

Male genitalia. Uncus short, slightly widened distally, with a small notch on posterior margin. Gnathos narrow, slightly curved, apically tapered, noticeably longer than uncus. Gnathos arms slightly curved. Valva rather long, narrow, poorly sclerotized. Anellus arms short, wide. Saccus basally wide, rounded. aedeagus narrow, straight, 1,5 times longer than entire genitalia, basally and medially with small needle-shaped cornuti.

Female genitalia. Papilla analis narrow, elongated. Posterior apophyses thin, straight, anterior apophyses significantly longer than posterior ones. Antrum wide, goblet-shaped. Rounded sclerotized swelling at confluence of ductus to antrum, ductus smoothly passing to elongated bursa copulatrix, bursa slightly widened distally. Signa absent.
