Rediscoveries and Presumed Extinctions of Hawaiian Leaf-roller Moths (Lepidoptera: Tortricidae).

Presumed extinct. This species is known only from two males collected by R.C.L. Perkins in 1892 at 4000 ft near Kona, Hawaiʻi island (Walsingham 1907). Although possibly a color form of the koa-feeding C. walsinghamii (Butler), Oboyski (2011) considered it distinct based on subtle differences in the male genitalia. Perkins’ field notes for September 1892 indicates that he “collected … by sifting dead leaves at the foot of a big koa tree” (Evenhuis 2007). The forewings are very similar to C. conspicua (Walsingham), but the absence of a “sex pouch” (Zimmerman 1978) on the ventral surface of the male hindwing readily separates it from that species.
