The Confused Identity of Frankliniella williamsi (Thysanoptera: Thripidae)

Abstract Details of the variation in the pronotal chaetotaxy among the type specimens of Frankliniella williamsi Hood and Frankliniella spinosa Moulton (Thysanoptera: Thripidae) are provided. We reject the recent revalidation of F. spinosa and conclude that the corn thrips, F. williamsi, is a single, variable species.
