Discussion
Remarks. Due to the presence of a deep prodorsal notch and spatulate dorsal setae, the new species resembles four species: Aegyptobia baptus Pritchard & Baker, 1952; A. crotonae Baker & Tuttle, 1972; A. haplopappus Baker & Tuttle, 1972; and A. semper Chaudhri & Akbar, 1985. However it differs from all of them by having setiform and barbed dorsal setae on femora and genua I–II, instead of broad setae. Aegyptobia hormozgani also differs from A. haplopappus and A. semper in having two pairs of pores instead of one pair. The new species resembles Aegyptobia forma Chaudhri 1972, also collected from Artemisia, in having similar spatulate and smooth dorsal setae, having two setae on trochanter III and one seta on genu III and a deep notch on anterior margin of propodosoma. It differs from A. forma in having a dorsal pattern of longitudinal ridges (A. forma has a finely striate dorsal pattern). Furthermore our species resembles Aegyptobia nasicornensis Meyer & Van Dis, 1993 in the length of the infracapitulum, the presence of hysterosomal pores and form of the anterior margin of the propodosoma, but it differs from A. hormozgani by having serrate dorsal setae (smooth in A. hormozgani), lanceolate dorsal setae of femora and genua I, II, similar to idiosomal dorsal setae (are setiform and barbed and are not similar to the body dorsal setae in A. hormozgani). Aegyptobia cedermontana Meyer & Van Dis, 1993 also resembles the new species in having the anterior margin of propodosoma notched, leg chaetotaxy and the presence of hysterosomal pores, but differs in having dorsal setae not serrated and dorsal setae on the femora and genua I–II not similar to the dorsal body setae.
