Afroicelita Aarvik , gen. nov.

Type species: Stenentoma pholicosta Razowski & Wojtusiak, 2012

Head. Frons below with appressed scales. In males, a group of rigid forward directed scales form a protruding crest between the bases of the antennae. In females the crest is less developed,

formed by tuft of curved scales. Labial palp of same length as diameter of eye or slightly exceeding it, third segment short, drooping. Thorax and appendages. Thorax ventrally smooth scaled. No modification of legs. Forewing with falcate apex, all veins separate, males with costal fold to 2/5 from base, bent under the wing. Hindwing costa concave in apical two fifths which is edged with long hairs, dorsal edge also concave; vein M2 bent close to short stalk of M3 and CuA1; costa in males with dense cover of dark, modified scales; anal region of hindwing without modification. Male genitalia ( Figure 17 ). Tegumen without uncus and socii; gnathos two band-like lobes; valva with rectangular sacculus, with group of strong spines on dorsal edge and along the ‘neck’ of the valva; cucullus rounded, spined along ‘neck’ and in ventral and apical part, with one strong thorn on terminal edge; phallus pistol-shaped, with four spindle shaped cornuti of different length. Female genitalia ( Figure 18 ). Ovipositor telescopic, papillae anales fused posteriorly; sterigma with two large lateral lobes that are pointed anteriorly, ductus seminalis arising at middle of ductus bursae, ductus bursae with sclerite between this point and edge of segment 7; corpus bursae broad in posterior half, with numerous denticles and two long, curved signa.

Diagnosis. Afroicelita gen. nov. has falcate forewings, a character which is present in many genera of Enarmoniini , e.g. the widespread Ancylis Hübner, 1816 , and in some genera of Eucosmini , e.g. Rhopobota Lederer, 1859 . However, Afroicelita gen. nov. differs from them by the presence in the male of a forward directed crest on the head, and the unique forewing costal fold which is folded on the underside of the wing.

Remarks. At the moment only Afroicelita pholicosta ( Razowski & Wojtusiak, 2012) comb. nov. is assigned to the genus. The female genitalia show similarities with those of species in the genus Icelita , but the male genitalia and sexual modifications of the male hindwing are very different; compare figures in Clarke (1976) and Horak (2006).
