Related and similar species

The genus Ewartithrips was proposed for six species from California, although separation of this from the Mediterranean genus Tenothrips has been questioned (Bhatti, 2003). E. flavidus is structurally similar to E. ehrhornii , from which it apparently differs in body color.
