Scolothrips takahashii Priesner 1950: 52 Scolothrips priesneri Sakimura 1954: 357 syn.n. The female holotype from Taiwan on which S. takahashii was based has been re-examined (in SMF) and compared with paratype macropterae of both sexes of S. priesneri from Hawaii (in SMF and UCD). These specimens are here considered to represent the same species and, although this is closely similar to longicornis, it differs in having the metascutellum shaded (as in rhagebianus) rather than clear yellow as in longicornis. The identity in California of a species that is represented in the collections at UCD by 21 females and 10 males from almond trees at Esparto remains in doubt. The males are all fully macropterous but, in contrast to takahashii, the metascutum lacks any shading. It is not possible at present to decide if thorax colour and male wing-length are stable characters that distinguish species in the longicornis species-group.
