Related species

This is the only species placed in the genus Striathrips, and its relationships are not clear. The lobed tergal craspeda and presence of one dorso-apical seta on the first antennal segment suggest that it might be related to Bregmatothrips, but the tergal campaniform sensilla are placed far forward of the posterior margin, and ocellar setae pair I are not present.
