Interpretive Summary: Frankliniella species are tiny insects that usually infest flowers. Several species (i.e. western flower thrips) are agricultural pests of which four are vectors of several viruses that cause serious disease of cultivated crops. Many species are variable in color or distinguishable only by minor anatomical differences and consequently are difficult to identify. These variations have resulted in the same species being described several times as different species. The 297 species assigned to this genus, the incorrect designations of species in the current catalogue of the genus and the many recently described species also have complicated the study of this group of insects. Representatives of nearly all known species were examined to determine which were the valid species. This list will provide researchers and regulatory officials the correct basic information required in studies of the Frankliniella species and development of improved methods of identifying the species and controlling their damage to crops.
Two hundred ninety-seven taxa (species, subspecies, varieties, forms) assigned to Frankliniella are treated in this list, of which 159 taxa are considered to be valid species in the genus. Treated as junior synonyms are Frankliniella argentinae Moulton and F. cestrum Moulton = F. australis (Morgan); F. conspicua Moulton, F. nubrosa Treherne, F. tritici var. maculata Priesner and F. umbrosa Moulton = F. occidentalis (Pergande); F. gossypii (Shiraki), F. persetosa Karny and F. tabacicola Karny = F. schultzei (Trybom); F. grandis Moulton = F. stylosa Hood; F. tritici (Fitch); F. stylosa f. colombiensis Moulton = F. panamensis Hood; and F. vicina Karny = F. intonsa (Trybom). Frankliniella obscura Moulton previously synonymized under F. occidentalis (Pergande) and F. difficilis f. minor Moulton under F. difficilis Hood are revalidated as good species (Revised Status). Lectotypes are designated for Euthrips maidis Beach, E. cephalica var. reticulata Craword and F. persetosa Karny.
