Humeral shields located ventrolaterally with setae c 2. Coxisternal shields divided along midline. Aggenital shield with two or three pairs of setae. Anogenital covers with three pairs of psudanal setae, genital setae absent. Chelicerae basally fused. Palptibial claw subequal to or slightly longer than palptarsus; accessory claw stout, tooth-like. Palp tarsus with a tridentate, terminal eupathidium. Subcapitulum with two pairs of subcapitular setae. Males often with lateral lamellae or protuberances on rostrum. Leg tarsal claws robust; empodial shaft branching into tenent hairs before extending beyond tips of claws, with three pairs of tenent hairs. Solenidia on leg tarsi I–IV: 1–1–1– 1 in female, 2–2–2– 2 in male ( Summers & Ehara 1965; Koç 2005; Fan & Zhang 2005; Khanjani et al. 2010).

Up to now a total of 25 species of Cheylostigmaeus have been described worldwide (Khanjani et al. 2010). Currently this genus is represented by two species in Turkey, namely C. salmani Koç and C. californicus Summers & Ehara ( Koç 2005; Doġan 2007; Akyol & Koç 2010), and this paper adds two species, C. urhani sp. nov. and C. salinus Evans , to the mite fauna of Turkey.
