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

Abstract

Three species of endemic Hawaiian leaf-roller moths were rediscovered after a 90-year gap in collection records. Twenty-one other species are presumed extinct, with no collection records from the past 50 years. Remarks concerning the type localities of four species (Cydia chlorostola, C. gypsograpta, C. parapteryx, and Pararrhaptica leucostichas) described by Meyrick are given. A list of all described endemic Hawaiian Tortricidae is provided with corresponding years for when each species was last reliably seen or collected as well as the type locality (when known). For each species, we include a list of known or hypothesized host plants, which we hope will spur future rediscoveries and conservation efforts for this group which has, to date, been ignored in conservation planning.
