Specimens examined. One female, formerly identified as A. cydnodactylon by M.A. Zaher, from soil under citrus tree, at Ashmoun, Monufia governorate, April 1977 (coll. M.A. Zaher); two females from soil, at Beheira governorate, July 2001 (coll. A.H.M. Romeih); six females from soil, at Demu Village, Senuris, Fayoum governorate, August and October 2006, May–November 2012 (coll. R.I.A. Abo-Shnaf); one female from soil, at October 6 city, Giza governorate, October 2006 (coll. R.I.A.

Previous records from Egypt. as A. cydnodactylon —Alexandria and Giza governorates (Shehata & Zaher, 1969); as N. barkeri —Asyut, Beni Suef, Damietta, Monufia and Qualyubia governorates (Nasr et al., 2011); Fayoum and Giza governorates (Romeih et al., 2010b).
Remarks. Neoseiulus barkeri was originally described from the holotype female collected in England. The original description was detailed, with illustrations, but with no measurements; complementary descriptions were listed by Demite et al. (2014).
Amblyseius cydnodactylon was originally described from the holotype female, seven paratype females and six paratype males, collected in the Faculty of Agriculture Farm, Giza governorate, and Burg El Arab, Alexandria governorate, Egypt. The original description was quite detailed, with illustrations and setal measurements. Measurements of specimens examined in this work fit the corresponding ranges given by Ferragut et al. (2010).
