Remarks

• Systematics: Slide-mounted adult female with: enlarged setae conical, sides concave basally, apices slightly rounded, marginal setae conspicuously larger than other dorsal setae, 2 lateral setae on margin of each abdominal segment (Danzig, 1962a).
• Structure: Adult female is oval and brown. Sac is white (Borchsenius, 1949). According to Archangelskya (1931), "Male second instar before pupation enclosed in elongate white felted sac with an aperture on its hind end. The male sac is comparatively more flattened than that of the female. Male imago bright red, pilose, with short stylus and 2 long white waxy filaments twice as long as the body. Antennae long and hairy, wings colorless."
• Biology: This species, with 2 broods per season, is found in the vicinity of Samarkand and Old Bokhara on roots of Zygophyllum fabago, Artemisia sp., and Dodartia orientalis, in 1927 and 1928 its principal food plant being Z. fabago. Newly hatched first instars, spreading around on the ground, are sometimes found attached to other plants also, but in very small quantities. Many females were observed infested by Hymenoptera (Archangelskya, 1931).
• General Remarks: Detailed description and illustration by Borchsenius (1949).
