SYSTEMATIC PART Atakterges gen. n. Figs (1-4, 13, 14) Type species: Lophoterges fidia DRAUDT, 1950, Mitt, munch, ent. Ges. 40 : 57. Type locality: China, North Yuennan, A-tun-tse. Species included: -fidia (DRAUDT, 1950) (= areolona (DRAUDT, 1950) syn. n. Diagnosis - Atakterges has the closest relationship with Speidelia gen. n. and Xylocampa GlJENÉE, 1837, representing presumably the sister-group of the Speidelia-Xylocampa line. These three genera display easily recognizable similarities in the external appearance (stature of the body with hood-like collar, shape and general pattern of wings) and in the genitalia of both sexes. The characteristic autapomorphies of the genitalia ox Atakterges are the helicoid coiling of the vesica with two full coils, the lack of the terminal cornutus (male), the similarly helicoid structure of the cervix bursae with heavily sclerotized plates and crests inside (female), these complementary parts of the copulatory organs display a very evident example for the "lock and key" model. In addition, the whole male copulatory organ of Atakterges is significantly larger than in the two related genera, the valva is stronger, broader, distally more dilated, the pollex-like extension is shorter, less prominent, the harpe is longer, narrower, more stick-like. The carina is unspecialized, without large, heavily sclerotized, dentate or serrate, saw- or crest-like plates. In the female genitalia the ductus bursae is membranous with weak medial sclerotization, the cervix bursae is considerably larger than the corpus bursae. The female genitalia of the Speidelia species have also bilobate bursa but it is most often more or less horseshoe-shaped, the cervix is much smaller than the corpus bursae, broadly tubular-sacculiform or slightly twisted, its walls are entirely membranous, except the sclerotized terminal "cap" around the ductus seminalis. The sclerotization of the ductus bursae is significantly stronger in Speidelia, most often the whole ductus is sclerotized, flattened. The bilobate bursa copulatrix of Xylocampa has almost equally large cervix and corpus bursae, the former is sacculiform, its basal part scobinate and wrinkled, the corpus bursae is membranous with long, narrow signum-stripe at middle. Description - medium-sized species, wingspan 33-35 mm, length of forewing 15-16 mm. Head strong, frons smooth, convex, covered with long hairs, eyes large, globular, eye-lashes well-developed. Palpi slender, upturned, first two joints with long hairs ventrally, third (apical) joint slender,
