Interpretive Summary: The majority of the leafroller (tortricid moths) fauna of Chile and Argentina is poorly known. Because many of the indigenous tortricid species have widened their host plant ranges to include cultivated plants, such as citrus (Citrus spp.; Rutaceae), grapes (Vitis spp.; Vitaceae), and stone fruits (Prunus spp.; Rosaceae), the threat of importation and establishment of these species into areas that import agricultural commodities from Chile and Argentina may be relatively high. Hence it is important to name, describe, and illustrate these species to facilitate identification and enhance the potential for their future detection. The purpose of this paper is to present illustrations and descriptions of a new genus and its two species from Chile and Argentina. This information will be useful to scientists studying leafrolling moths and to regulatory personnel charged with keeping foreign species moths out of the U.S.
Acamanthina, new genus, is described and illustrated from Chile and Argentina. The new genus includes two species: A. acmanthes (Meyrick, 1931) (type species), new combination, and A. albipuncta, new species. Acmanthina can be distinguished from all other genera in Euliini by two external features of the males: the absence of cubital pecten on the hindwing (present in females) and the possession of a long, slender hairpencil concealed in a deep fold along hindwing vein CuP.
