Metanotum weakly reticulate, median setae longer than lateral pair and arising at anterior margin, paired campaniform sensilla present medially. Fore wing first vein with about 6 setae on distal half, second vein with 12 setae. Abdominal tergites with no sculpture medially, without ctenidia; tergite VIII with long regular marginal comb.

Related species

This species was described in Ewartithrips, a genus proposed for six species from California. However, separation of this Californian genus from the Mediterranean genus Tenothrips is doubtful (Bhatti, 2003). T. flavidus is structurally similar to T. ehrhornii, from which it apparently differs in body color.

Biological data

Collected from plants in several families, including Ceanothus [Rhamnaceae], and presumably living in flowers.
