This species is named in honour of Prof. Dr. Nusret Ayyıldız (Erciyes University, Kayseri, Turkey ) for his great and valuable contributions to Acarology in Turkey . Type materials. Holotype Ƥ, 6 paratypes ƤƤ, 1 deutonymph Ƥ from grassy soil, 40°27'23'' N , 37°02'51'' E , 362 m , between Reşadiye-Niksar, 08 XI 2008 ; ZMAU . Remarks. This new species resembles Stigmaeus malekii Haddad, Bagheri & Khanjani, 2006 in lacking of reticulations on the dorsal shields, the central shield bearing three pairs of setae, divided intercalary shield, femur II with four setae and three pairs of aggenital setae located on the same shield. However, it can be distinguished from the latter by the presence of apodemal marking on the idiosoma, one pair of eyes, post-ocular bodies evident and different numbers of setae on leg genua I–II and tarsi I–II. Genua I–II have 4(κ)–4(κ) and tarsi I–II have 14(ω)– 10(ω) in the new species whereas these counts are 3–3, 13(ω)–8(ω) respectively in S. malekii .
