Abstract

The most recent taxonomic treatment of North American moths of the genus Agonopterix Hübner (Lepidoptera: Gelechioidea: Elachistidae) recognized two Rutaceae-feeding species, Agonopterix nigrinotella (Busck) and Agonopterix pteleae Barnes and Busck. Ecological, morphological, and molecular data presented in this paper indicate that four species of Agonopterix feed as larvae on Rutaceae in Illinois. Agonopterix costimacula Clarke (revised status) and A. pteleae feed on hoptree, Ptelea trifoliata (Linnaeus). Both of these species are multivoltine. Agonopterix nigrinotella and a previously unrecognized species, described here as Agonopterix paulae Harrison, n. sp., feed on pricklyash, Zanthoxylum americanum Miller. Agonopterix nigrinotella is univoltine, whereas A. paulae is bivoltine. Larval feeding tests determined that each of the four species is strictly monophagous and that literature reports of A. nigrinotella on Carya sp. and Agonopterix argillacea (Walsingham) on Ptelea trifoliata are apparently erroneous. Diagnoses and dichotomous keys are given for identifying mature larvae and adults of the four Rutaceae-fceding species.
