Interpretive Summary: MothsofthegroupknownasEuliiniareprimarilyNeotropicalin distribution, where the larvae are pests of grapes, citrus, stone fruits, kiwi fruit, pines, and many other cultivated and ornamental plants. A large proportion of the group is represented by undescribed (un-named) species, obscuring their relationships and diminishing our ability to identify them accurately. The purpose of this paper is to describe a new genus and two new species. The new genus is known from Costa Rica and Venezuela. The descriptions and illustrations presented in this paper will facilitate identification of these species when encountered by APHIS or other quarantine personnel.

Technical Abstract: Eubetia, new genus, is described and illustrated from Central and South America. The new genus includes two species: E. bigaulae, new species, (type species) from Venezuela, and E. ras, new species, from Costa Rica. Adults are superficially most similar to Anopina Obraztsov and Odonthalitus Razowski; male genitalia are most similar to Anopinella Powell. Males of E. bigaulae possess a preponderance of putative secondary sexual characters, including the typical euliine foreleg hairpencil, a swollen area near the base of the forewing costa, a dense patch of elongate androconial scales on the lower surface of the forewing, modified scales in the anal and costal regions of the hindwing, and a band of specialized scales at the terminal edge of abdominal segment IX. In addition, males of this species have an unusual row of dense, ascending scales on the lower frons, and forewing veins M3 and CuA1 are stalked; the latter two features are found in no other Euliini.
