Cydia Hübner, [1825] 1816

Type species: Phalaena (Tortrix) pomonella Linnaeus, 1758 .

Brown (2005) included more than 225 species in Cydia, but the monophyly of the group has not been investigated thoroughly, and it is highly likely that many species assigned to the genus belong elsewhere. As currently defined, Cydia is worldwide in distribution, occurring in every major biogeographic realm; the type species, Cydia pomonella, is a nearly cosmopolitan pest of apples. Male genitalia are characterized by the reduction or loss of the uncus, socii, and gnathos. Hence, it is possible that many species are assigned to Cydia on the basis of parallel reductions in these structures, including the species described herein.

Species of Cydia have been recorded from a wide range of plant families, including Arecaceae, Betulaceae, Boraginaceae, Cupressaceae, Cyperaceae, Fabaceae, Fagaceae, Juglandaceae, Moraceae, Oleaceae, Pinaceae, Rosaceae, Rubiaceae, Salicaceae, and Sapindaceae (Brown et al. 2011) . Most species feed internally on fruit, with the majority of host records from Fabaceae; as mentioned above, the codling moth ( Cydia pomonella) is an economically important pest of the fruit of Rosaceae (e.g., apples, pears, peaches, plums).
