Title: A New Species of Galeopsomyia (Hymenoptera: Eulophidae: Tetrastichinae): A Fortuitous Parasitoid of the Citrus Leafminer, Phyllocnistis citrella (Lepidoptera: Gracillariidae)
Abstract: Galeopsomyia fausta LaSalle sp.n. (Hymenoptera: Eulophidae: Tetrastichinae) is described as a fortuitous parasitoid of the citrus leafminer, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae: Phyllocnistinae). This species is widely distributed in the Neotropics, being known from Mexico and Puerto Rico to Argentina. G. fausta is the first species of Galeopsomyia which is not associated biologically with galls. G. fausta represents an example of an indigenous parasitoid recruited onto an invading pest species, and the implications of this for the valuation of biodiversity are discussed.
