Interpretive Summary: Tortricid moths are often pests of U.S. crops and can cause substantial damage. The tortricid tribe Euliini is primarily Neotropical in distribution; the larvae are pests of grapes, citrus, stone fruits, and many other cultivated and ornamental plants. A large proportion of the tribe is represented by undescribed species, and many of the described species are placed in the wrong genera, obscuring relationships and diminishing our ability to identify them accurately. The purpose of this paper is to describe a new genus to accommodate one formerly misplaced species and one new species. The new genus occurs from Costa Rica south through Colombia, Venezuela, Peru, and Ecuador. This information will be useful to regulatory personnel charged with identifying insects and to scientists trying to control pest moths on crops.

Technical Abstract: Strophotina, new genus, is described to accommodate S. strophota (Meyrick, 1926), new combination, from Colombia, Venezuela, Peru, and Ecador, and S. curvidagus, new species, from Costa Rica. The new genus is most similar to Anopinella Powell, Seticosta Razowski, and Galomecalpa Razowski in general facies and characters of the genitalia. Strophotina may represent the sister group of Galomecalpa on the basis of the shared posession of extremely elongate, narrow, short-scaled male foreleg hairpencil. Putative autapomorphies for Strophotina include the greatly expanded patch of spinelike setae subbasally on the costa of the valva, the highly modified, elongate mesal processes of the transtilla, and the narrow, elongate, curved aedeagus.
