Legs. Macrosetae knobbed-tipped: Sge IV 23, Sti IV 22, St IV 41; chaetotaxy of genua II and III as in female.

Specimens examined. Five females and one male from soil under cucumber plant, at Etay El Baroud, Beheira governorate, June 2005 (coll. A.A. Mohamed); one female from same substrate, at Giza governorate, January 2005 (coll. R.I.A. Abo-Shnaf).

Previous records from Egypt. as T. pectinatus —unspecified governorate (Zaher & Shehata, 1969); as T. transvaalensis —Alexandria, Cairo, Giza and Ismailia governorates ( Zaher, 1986); Asyut, Beni Suef, Damietta, Monufia and Qualyubia governorates ( Nasr et al., 2011).

Remarks. Typhlodromus transvaalensis was originally described from the holotype female and a paratype female collected in South Africa. The original description was reasonably detailed, with illustrations but no measurements; complementary descriptions were listed by Demite et al. (2014). Typhlodromus pectinatus was originally described from the holotype female collected in Algeria. The original description was rather detailed, with illustrations and setal measurements. Measurements of the specimens examined are close to those provided by Swirskii et al. (1998).
