Diagnosis.— Farragona can be distinguished from all other Neotropical Archipini by the following combination of features: male genitalia with uncus bifid; tegumen robust; gnathos difficult to interpret, but appears to have arms widely separate, rounded apically, with round, plate-like structure mesally; valvae simple, rounded, with narrow sclerotization on dorsal and ventral edges; phallus sickle-shaped, apically pointed, with caulis long, arising at base; female genitalia with papillae anales conspicuously narrowed latero-mesally with large, well-sclerotized dorsal hood; and signum long, sickle-shaped with capitulum small and opposing. Adults have a strongly concave forewing costa with the apex pronounced and the forewing pattern similar to that of Argyrotaenia Stephens and Clepsis Guenée.

Etymology.—The genus name is from farrago (Latin) for ‘mixture,’ referring to the odd combination of features in the male genitalia, almost as if the parts had been borrowed from different archipine genera and stuck together. It is interpreted as feminine in gender.

Remarks.—We were unable to physically examine Tortrix cratista or Tortrix cremnobates to provide a description for this new genus. Our diagnosis is based solely on the photographs of Tortrix cratista adults and genitalia slides present in the BMNH. The lectotype of T. cratista is missing its head, so any description would be limited in scope regardless. The ICZN does not require a description for a new genus, only a diagnosis and type species designation (ICZN Articles 13.1.1, 13.3.1).
