Previous records from Egypt. as T. athiasae —Giza and Monufia governorates (Zaher, 1986); Nile Delta region (Rasmy & Abou-Awad, 1972); unspecified governorate (Zaher & Shehata, 1969); as T. pelargonicus —Giza governorate (Zaher, 1986); Cairo governorate (El-Badry, 1968b); Qualyubia governorate (Zaher, 1986); as T. siwa —Fayoum and Giza governorates (Romeih et al., 2010b); Siwa Oasis (El-Badry, 1967a; Zaher, 1986); unspecified governorate (Zaher & Shehata, 1969).
Remarks. Typhlodromus athiasae was originally described from the holotype female, eight paratype females and two paratype males collected in Israel. The original description was reasonably detailed, with illustrations and setal measurements; complementary descriptions were listed by Demite et al. (2014). Typhlodromus siwa was originally described from the holotype female and a paratype female collected in Siwa Oasis, Egypt. The original description was brief, with illustrations but without setal measurements. Typhlodromus pelargonicus was originally described only from the holotype female collected in Shubra, Cairo governorate, Egypt. The original description was reasonably detailed, with illustrations and setal measurements.
Measurements of the examined specimens are close to those provided in the original description of T. athiasae, for both females and males, and those provided by Chant & Yoshida-Shaul (1987) for females. However, the type specimens of T. athiasae are mentioned to have a single macroseta, on basitarsus of leg IV. Measurements of the specimens examined are close to those reported by Zaher (1986) for a single female of T. pelargonicus.
