Analysis of morphology and sequences of the 658bp barcoding region of COI support four distinct species in the genus Frumenta Busck, 1939, two of which are described new: Frumenta davidi McCarty, new species, and Frumenta dianeae McCarty, new species. Frumenta solanophagaAdamski and Brown, 2002, is a junior synonym of F. nephelomicta (Meyrick, 1930). Frumenta nundinella (Zeller, 1873) and F. nephelomicta are redescribed. Sequence data for F. dianeae were unavailable, but the morphology of this species is distinct. We found three morphological features that may define Frumenta and provide support for the placement of Frumenta within Gnorimoschemini Povolný, 1964, including a culcitula revealed by scanning electron micrographs. Images of adult habitus and male and female genitalia are provided as well as a map showing species distributions and a key to the species.
