Diagnosis . Dysdera sultani is closely related to the Turkish endemic species D. argaeica , according to the basic characte- ristics of the male copulatory organs, such as the cylindrical shape of the bulbus, the massive structure of the posterior apophysis, and the development of the internal and external sclerites on the bulb. The most obvious difference between the males of these two species is the angle and shape of the structures towards the distal part of the bulb. The vulvae of D. sultani and D. argaeica are similar, but the midline of the transverse bar is more flattened in D. argaeica as opposed to crescent shaped in D. sultani . Additionally, the posterior di- verticulum is membranous and well-developed in D. argaeica. Measurements ( ) / ( ).

Medium-sized dysderid spiders. Male speci- mens are slightly darker than females. Prosoma reddish brown. The cephalic region is lighter than the thoracic region and is angular laterally. The eyes are closely grouped; anterior-median eyes are more distant from each other (Fig. 1). Chelicerae brown. Cheliceral groove with three small teeth. Distance between basal and medial teeth is half of the distance between distal and medial teeth (Fig. 2). Labium, gnathocoxae and sternum reddish brown and margins blackish brown. Labium reddish brown from the ad- jacent edge of the sternum to approximately the tip of the sternum; the tip much lighter, orange and concave. The sur- face of the sternum bright with nearly uniform weak black hairs and brown margins. Setae longer in males. Pedicel strongly developed, sclerotized and brown dor- sally and ventrally. Legs yellowish to light brown, with the first three segments of the anterior legs darker than the other segments. Front legs spineless. Femora of all legs with dorsal spines in both sexes. Leg measurements and spination are gi- ven in Tab. 1 and Tab. 2. Scopulae present on tarsi and metatarsi of all legs. Howe- ver, the scopulae of the 3 rd and 4 th legs are well developed and more distinct than the other legs. Opisthosoma greyish; cylindrical and more swollen in females. The surface covered with short blackish hairs on both the dorsal and ventral sides. Distinct colour difference between the spinnerets and opisthosoma in both sexes. Spin- nerets darker brown than opisthosoma and almost the same colour as the legs. Epigastral scutum is present and weakly developed. Tracheal spiracles are sclerotized. The female palp is the same colour as the legs; palpal tar- sus with a single-claw, and almost the entire surface is densely covered with thick hairs.
