Remarks
- Systematics: This species has spiculae on the anal ring and tritubular cerores which are 3-4 times longer than wide. (Suh, et al., 2013)
- Structure: Field characters: Adults and nymphs oval elongate, white, 1.2-1.5 mm long. Slide-mounted characters: Anal lobes poorly developed on dorsum, each lobe bearing 1(2) long ventral seta and 1(2) long dorsal apical setae. Antennae 6-segmented. Circulus present on abdominal segment III; sclerotized truncate-cone shaped, with distal circular plate containing 7 circular cells. Eye small. Cephalic plate present at anterior to clypeus; a quadrate sclerotized area containing 4 marginal setae. Multilocular disc pores absent. Tritubular cerores present each with truncate-conical tubes; on dorsum, not numerous, less than 3 on abdominal and thoracic segments; a few scattered on head; on venter, a single marginal pore on some of posterior abdominal segments; one on thorax and one between antennal base. Anal ring pores with numerous spiculae, tritubular cerores situated on margins somewhat larger than other areas and length of labium. (Suh, et al., 2013)
- Biology: Occurring on the roots of grasses. Life history, natural enemies and associated ants discussed by Kosztarab & Kozár (1988F). Parasites in Palaearctic region discussed by Trjapitzin (1989). Biology and ecology discussed by Kozarzhevskaya (1992).Living on roots of its host plant. Females are ovoviviparous and all stages overwinter, except first instars; males do occur in this species. There are two generations per year (Jansen, 2009).
- Economic Importance: Has been recorded as causing extensive damage (Williams, 1962).
