Cydia obliqua (Walsingham)

Presumed extinct

This species is known from three female specimens collected at Hualālai (5000 ft) and Kona (4000 ft) on Hawaiʻi island by R.C.L. Perkins in 1892. Oboyski (2011) considered it possibly just an extreme color form of the widespread and polymorphic C. plicatum (Walsingham) , but refrained from synonymizing it because of significant differences in the female genitalia. The collection date given for the two female types from Hualālai (5 viii 1892) corresponds to a journal entry in which Perkins wrote, “there were two Tortricids on Koa” ( Evenhuis 2007).
