This species has not been studied by the present authors. According to Nakahara (1995: 236) it is distinguished from the other five species he placed in Ewartithrips in having the comb on tergite VIII irregular or missing medially. Females are either fully winged or short winged, but only short-winged males are known (Nakahara, 1996: 239).
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).
Collected from Amsinckia sp. (Boraginaceae), and presumably breeding in flowers.
Known only from California.
