Specimens examined. Holotype female of T. balanites from B. aegyptiaca, at Shambat city, North Sudan, December 1966 (coll. E.A. El-Badry); holotype female, one paratype male and one male of T. mangiferus from mango leaves, at Giza governorate, September 1977 (coll. M.A. El-Borolossy); one female from same substrate and locality, February 1987 (coll. M.A. Zaher); one female from organic manure at Nasser, Beni Suef governorate, April 2001 (coll. A.H.M. Romeih); two females from mango leaves, at Senuris, Fayoum governorate, December 2002 (coll. R.I.A. Abo-Shnaf); one male from same substrate and locality, July 2003 (coll. R.I.A. Abo-Shnaf); one female from same substrate and locality, January 2004 (coll. R.I.A. Abo-Shnaf); one female from apple leaves, at same locality, March 2003 (coll. R.I.A. Abo-Shnaf); two females from Z. jujube leaves, at the Faculty of Agriculture Farm, Cairo University, Giza governorate, August 2001 (coll. M.M. Ahmed).
Previous records from Egypt. as T. balanites — Fayoum governorate (Romeih et al., 2010b); Giza governorate (Zaher, 1986; Romeih et al., 2010b); as T. egypticus —Cairo governorate (Zaher, 1986); Giza governorate (El-Badry, 1967a; Zaher, 1986); as T. mangiferus —Giza, Ismailia and Matrouh governorates (Zaher, 1986).
Remarks. Typhlodromus egypticus was originally described from the holotype female and T. mangiferus from an unstated number of type specimens, both from Giza governorate, Egypt. The original descriptions of T. egypticus and T. mangiferus were reasonably detailed and illustrated; setal measurements were provided for T. mangiferus but not for T. egypticus. Typhlodromus balanites was originally described from the holotype female, 34 paratype females and five paratype males collected in North Sudan. The original description was rather detailed, with illustrations and setal measurements.
An examination of the type specimen of T. balanites showed this to be a junior synonym of T. egypticus. El- Badry (1967a, 1970) reported the chelicera of T. egypticus to have no teeth [sic], while Chant & McMurtry (1994) mentioned species of what they called the “ egypticus species group” to have chelicera with few teeth [sic]. Despite our effort, it was not possible to obtain types of T. (A.) egypticus for examination in this study. Thus, the new synonymy proposed in this paper is based on an examination of types of T. mangiferus, on the original description of T. egypticus, on the fact that both nominal species were described from the same region and on the several additional females and males examined in this study. Our measurements of T. mangiferus holotype are close to those reported by Zaher (1986) for a single female, except z2 (30 according to that author).
