Ventral opisthosomal area with three to five pairs of aggenital setae, genital and anal valves fused or contiguous, with one to three pairs of genital setae and three pairs of pseudanal setae. Chelicerae separate. Palptibial claw subequal to or slightly shorter than palptarsus; accessory claw setalike or spinelike. Terminal eupathidia on palptarsus basally fused and split into three long prongs. Counts of setae and solenidia from palptrochanter to palptarsus: 0–3–2–2 + 1 claw + 1 accessary claw–4 + 1ω + 1 subterminal spine-like eupathidium + three eupathidia (basally fused).

The genus Stigmaeus has a worldwide distribution with more than 100 described species. To date 16 species are reported from Turkey (Doġan 2007; Akyol & Koç 2007). The following five species are described here as new: Stigmaeus angustus sp. nov., S. ayyildizi sp. nov., S. additicius sp. nov., S. furcatus sp. nov. and S. kelkitensis sp. nov. Supplementary descriptions of two known species, Stigmaeus glabrisetus Summers and S. solidus Kuznetsov , which are new records for the Turkish fauna, are given. In addition, Stigmaeus siculus (Berlese) , S. devlethanensis Akyol & Koç , S. pilatus Kuznetsov and S. planus Kuznetsov , are recorded from new localities.
