Taxonomic Status and Host Range of Three Heteropsylla spp. (Homoptera: Psyllidae) in Hawaii

Abstract

The taxonomic status of two species of Heteropsylla in Hawaii was clarified after confusion arose because of inadequate identification keys and the collection of mixed populations from a common host plant. A third species of Heteropsylla was also discovered for the first time in Hawaii during January 1986. Most range tests were conducted with nine leguminous plants, Heteropsylla cubana Crawford, a senior synonym of H. incisa (Sulc), completed its development on leucaena (Leucaena leucocephala (Lam.) de Wit) and monkeypod (Samanea saman (Jacq.) Merr.); H. huasachae Caldwell on koa (Acacia koa Gray), monkeypod, and slender mimosa (Desmanthus virgatus (I.) Willd.); and H. fusca Crawford on klu (Acacia farnesiana (1..) Willd.).
