Remarks

• Systematics: Slide-mounted adult female with: dorsal setae hair-like or slightly enlarged, apices acute or rounded, abundant over dorsal surface; claw digitals shorter than claws; anal ring with 1 row of pores; microtubular ducts short, with 1 sclerotized area (Matesova, 1960a).
• Biology: The first instars of the scale appear in the middle of summer. They settle on internodal, terminal, or green twigs of Tamarix. The feeding first instar is gradually overgrown by fleshy green folds from which the shoot continues to grow. The folds close to form a gall. The cavity of the gall is smooth and irregular. In autumn the folds of the gall open and the female leaves. The galls abandoned by the females turn yellow, dry up and fall off (Matesova, 1960a).
• Economic Importance: This species infests Tamarix species so heavily that "the reduction of the assimilating surface in individual plants reaches 80 percent. The growth of such plants is conspicuously depressed (Matesova, 1960a)."
• General Remarks: Detailed description and illustration including that of first instar and an illustration of a gall, by Matesova (1960a).
