SYSTEMATIC PART Ethmia anatiformis sp. n. (Figs 1, 8-9, 15) Holotype-Male, "Nepal: 1750-1950 m, Phulchoki, mixed Schima-Castanopsis for., 27.V.1984, M. G. Allen, BM 1984-136"; slide No. BMNH Microlep. 29715, deposited in the BMNH. Paratypes - Nepal: 2 specimens, with the same data as the holotype; 1 female, from the same locality but from 19.VI.1984, slide No. BMNH Microlep. 29714; 1 male, Prov. Chisapani Garhi, Chisapani Garhi 1600 m, 11 -15. VIT. 1967, leg. DlERL & SCHACHT, slide No. KUN 159; 1 male, Prov. Nr. 1 East, Pultschuk, 23-2500 m, 12.VI.1967, leg. DlERL, FORSTER & SCHACHT, slide No. KUN 158. The paratypes are deposited in the collections of the BMNH, the ZSM and the HNHM. Diagnosis — The new species is related to E. maculata SATTLER, 1967 and E. hunanensis LIU, 1980. E. anatiformis differs externally from E. maculata by its larger size (wingspan of E. anatiformis is 33-36 mm, that of E. maculata 25-27 mm) and by the long arrow-shaped forewing marking, which is almost continuous in the new species but interrupted in the middle in E. maculata. In addition, E. anatiformis has the hindlegs with black rings and the hindwing is dark grey, while they are whitish grey in E. maculata. The male genitalia of the two species are strongly different (see Fig. 8, and KUN & SZABÓKY 2000, Fig. 12). According to the description of E. hunanensis, the forewing pattern of E. anatiformis is simpler, consisting of fewer spots and markings. The male genitalia of the two related species differ in the shape of the cucullus (see Fig. 8, and LlU 1980, Fig. 3). Description -(Fig. 1): Wingspan 33-36 mm. Antenna filiform, with slightly dilated basal segments; scape with black scales above and white scales below, flagellum with brown scales; maxillary palp whitish grey. Labial palp white with black scales on medial segment; base of proboscis white; frons and vertex white, similarly with black scales on top; thorax white with five black spots (Fig. 15); tegulae white with a pair of black spots at base. Forewing overlaid with black markings on whitish background; characteristic marking of forewing a long, arrow-shaped stripe runing from middle of cell to termen without large significant, rest of markings consisting of elongate spots. Hindwing dark grey; without costal brushes; cilia grey. Forelegs and inidlegs whitish with black rings, especially on tarsus, hindleg whitish grey with black rings. Abdomen grey, yellow from 5th to 8th segments, with two black spots on dorsal surface of each segment. Male genitalia (Fig. 8): Uncus bifid with deep medial incision, apices rounded. Posterior part of gnathos lacking, anterior part well developed, finely dentate, hairy, fused with large, sclerotizcd dorsal plates on each side. Labis membranous, narrow; dorsal part of anellus sclerotized. Valva with bristles; costal margin with well-developed triangular, sclerotized basal plate. Cucullus quadratic, with triangular apical lobe and with pointed outer extension, ventral surface covered with strong bristles; vinculum without developed Saccus. Aedeagus gun-shaped, cornuti long, bristle-like. Female genitalia (Fig. 9): Ovipositor strongly sclerotized, posterior apophyses thin, longer than papillae anales, anterior apophyses absent. Antrum membranous, with a sclerotized caudal ring. Ductus bursae thin, tubular, longer than abdomen; corpus bursae spherical with large appendix; Annls hist.-nat. Mus. natn. huni;. 93, 2001
