Legs. Macroseta with distal knob: St IV 41; chaetotaxy of genua II and III as in female.
Specimens examined. Holotype female and one paratype male from citrus leaves, at Senuris, Fayoum governorate, December 2003 (coll. R.I.A. Abo-Shnaf).
Previous records from Egypt. Fayoum governorate (Romeih et al., 2005).
Remarks. This species was originally described from the holotype female and an unstated number of paratypes collected in Fayoum governorate, Egypt. The original description was detailed, with illustrations and setal measurements. Measurements of this species are close to those of the original description, except S4 (26 in holotype).
