Abstract
A new species, Grapholita diehli n. sp., is described and illustrated from northern Sumatra, Indonesia. Among numerous new species of Tortricidae from Indonesia is one represented by a single specimen collected in Sumatra in 1992. Extensive sampling by many collectors over the past two centuries has resulted in no additional specimens of this unusual moth. The new species is the first described tortricid with a large light area apically in the hindwing; numerous other species have the hindwing highlighted overall, only basally, or not at all. The more typical condition is uniformly colored hindwings.
