Acmanthina: A new genus of tortricid moths (Lepidoptera : Tortricidae : Euliini) from Chile and Argentina

Acamanthina, new genus, is described and illustrated from Chile and Argenti na, and includes two species: A. acmanthes (Meyrick, 1931) (type species), new combination, and A. albipuncta, new species. Acmanthina can be distingu ished from all other genera in Euliini by two external and one genitalia fe ature of the males: the absence of elongate scaling in the basal portion of the hindwing along veins 1A + 2A and CuP (present in the female), the poss ession of a fascicle of 17-20 extremely long sex scales (=hairpencil) conce aled in a deep fold along the basal three-fifths of hindwing vein CuP, and the deep mesal excavation of the juxta. The new genus appears to be most cl osely related to Haemateulia Razowski.
