Diagnosis. N. orientalis   is very similar to N. palaestina   but can be distinguished by the shape of its median apophysis and its embolus, the base of retrolateral tibial apophysis not swollen in male, and by the shape of the spermathecae and their ducts in female.

Description- Male. Measurements: Body length 5.5–6.2; Carapace length 2.5–2.8; width 2.0–2.4; Abdomen length 3.0–3.4; width 2.0–2.6; length of legs: (I) 9.2–10.6, (II) 7.0–8.4, (III) 6.8–8.2, (IV) 11.4–12.8. Carapace nearly oval, slightly narrowed in front; reddish-brown with its upper parts lighty reticulated black and bordered with thin black line; ocular area darker, without setae; cephalic area slightly elevated, its sides emphasized by black contours; Thoracic groove distinct in the middle. Eyes in two rows; anterior row nearly straight, posterior row slightly recurved in dorsal view; AME smallest, nearly equal to PME, lateral eyes largest; PME oval, others nearly circular with black edge; median eyes closer to lateral eyes than to each other but not touching. Median eyes nearly separated by their diameter or more. Chelicerae, labium and endites darker than carapace. Chelicera with small fang and serrated carina on retromargin. Labium nearly triangular. Endites rounded, not swollen in the bottom. Sternum nearly heart-shaped, lighter than carapace, bordered by thin black line, densely covered by hairs on margins. Abdomen grey to dark brown with brown chevron and six oval brown spots on back, with dark longitudinal bands on venter. Legs reddishbrown. Patellae IV without setae. Leg formula 1423.

Male palp. Large brown retrolateral tibial apophysis at the base (in N. palaestina   the base of retrolateral tibial apophysis is nearly two times larger than in N. orientalis   ) with recurved hook at apex, ventral tibial apophysis light, small. Median apophysis hook shaped. Embolus long, wedge shaped with a protrusion near the base ( Figs 13–18).

Description. Female. As male, but larger body and slightly lighter in colour. Measurements: Body length 7.6–8.5; carapace length 2.8–3.1; width 2.1–2.6; abdomen length 3.8–5.4; width 2.7–3.4; length of legs: (I) 7.8–9.0, (II) 6.4–7.6, (III) 6.1–7.3, (IV) 9.8–10.9. Leg formula 4123.

Epigyne. Epigynal plate large, lateral contours of epigyne curved and elongated along the epigyne. Spermathecae nearly rectangular, very large, ducts next to each other basally, curved through the spermathecae in apex, but not touching them ( Figs 19–20).

Comments. The type locality of this species, which was described by Dalmas (1921) from Turkey, is not precise. The collecting sites of this species in detail with GPS coordinates are here presented in addition to its distribution map in Turkey ( Fig. 21).
