Remarks

• Systematics: Slide-mounted adult female with: enlarged setae conical, apices rounded, marginal setae slightly longer than other setae on dorsum (Tang & Li, 1988).
• Structure: Ovisac smooth, felted, cream colored (Kosztarab & Kozár 1988). Adult female is oval and pale rose in color (Matesova, 1957).
• Biology: This is a steppe inhabiting xerophilous species. In Kazakhstan, adults appear in May or June. Egg production (12-86) probably depends on host plant. Young females and molting last-stage nymphs were found at the end of May. It was at this time that the flight of the males began (Matesova, 1957). The ant Tetramorium semilaevi has been associated with this species. This species is found on the bases of leaves and root crowns of its host (Kosztarab & Kozár, 1988).
• Economic Importance: Often a pest in Kazakhstan (Kosztarab & Kozár, 1988).
• General Remarks: Detailed description and illustration by Matesova (1957) and Kosztarab & Kozár (1988).
