Specimens examined. Holotype female, one paratype female and one paratype male from Zizyphus sp. leaves, at Sohag governorate, December 1978 (coll. M.A. El-Borolossy); one female from Ficus sycomorus L. ( Moraceae ), at Aswan governorate, November 1980 (coll. M.A. Zaher). Previous records from Egypt . Sohag governorate ( Zaher, 1986 ); unspecified governorate (Nasr & Abou- Awad, 1985 ). FIGURES 27–33. Euseius yousefi : 27. Female dorsal shield; 28. Female ventral shields; 29. Female chelicera; 30. Spermatheca; 31. Genu, tibia and basitarsus of female leg IV; 32. Spermatodactyl; 33. Male ventrianal shield. Remarks. According to Nasr & Abou-Awad ( 1985 ) , A . yousefi was first described in an unpublished MSc thesis ( El-Borolossy, 1979 ). Nasr & Abou-Awad ( 1985 ) mentioned the name of this species (indicating El- Borolossy [sic] as the author) in a key to the Egyptian Amblyseius . That constitutes the original description of the species, despite the fact that no information was then provided about the type specimens. Zaher ( 1986 ) provided a detailed redescription of the species, with illustrations and setal measurements, mistakenly mentioning Zaher & El- Brollosy [sic] as the authors. Our measurements of the holotype are close to those reported by Zaher ( 1986 ) for a single female, except z 2 ( 37 according to that author).
