Specimens examined. Holotype female of Typhlodromus medanicus from cotton leaves, at Wad Medani, Gezira state, Sudan, October 1966 (coll. E.A. El-Badry); holotype female of Typhlodromus schusteri from citrus leaves, at Qualyubia governorate, July 1977 (coll. M.A. El-Borolossy); one female from soil under lawn grasses, at Giza governorate, April 1977 (coll. M.A. El-Borolossy); one female from organic manure, at Nasser, Beni Suef governorate, April 2001 (coll. A.H.M. Romeih); one female from soil under F. nitida , at Orman Botanical Garden, Giza governorate, May 2012 (coll. R.I.A. Abo-Shnaf).

Previous records from Egypt. as C. africanus —unspecified governorate ( Yousef, 1980); as C. cordiae —Giza and Matrouh governorates ( Zaher, 1986); unspecified governorate ( Muma, 1967); as C. negevi —Asyut, Beni Suef, Damietta, Monufia and Qualyubia governorates ( Nasr et al., 2011); as T. schusteri —Behira and Qualyubia governorates ( Zaher, 1986); Fayoum and Giza governorates ( Romeih et al., 2010b); as T. zaheri —Giza governorate ( El-Badry,1970); Minya governorate ( Zaher, 1986); Qualyubia governorate ( El-Badry, 1967a); Siwa Oasis ( El-Badry, 1967a; El-Badry,1970; Zaher, 1986); unspecified governorate (Zaher & Shehata, 1969).

Remarks. Typhlodromus negevi was originally described from the holotype female and one paratype female collected in Israel; T. africanus and T. schusteri were originally described from unstated numbers of types and from unstated localities in Egypt; T. cordiae was originally described from the holotype female and 16 paratype females and five paratype males collected in Pakistan; T. zaheri was originally described from the holotype female and an unstated number of paratypes collected in Egypt. The original descriptions of T. negevi and T. schusteri were detailed, with illustrations and setal measurements; the original description of T. africanus was reasonably detailed and well illustrated, but with no measurements; the original descriptions of T. cordiae and T. zaheri were abbreviated, with illustrations, but without setal measurements.

Measurements of the specimens examined in this study are close to measurements provided by Swirski & Amitai (1961) and Swirski et al. (1998) for C. negevi . Swiski & Amitai (1961) reported that C. negevi has a macroseta on tibia IV (44–50 long), a macroseta on basitarsus IV (26–29 long) and fixed digit with five teeth. Swirski et al. (1998) reported the presence of a single macroseta, on basitarsus IV (43–56). Measurements of the specimens examined are also close to those reported by Zaher (1986) for a single female.
