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).
