V.2007, leg. O. Seyyar & H. Demir (2♂♂, 2♀♀) ; Kahramanmara ş Province, Püren Pass , (37° 56' N, 36° 30' E), 1581m, on ground, 20. V.2007, leg. O. Seyyar, (1♂) .

Diagnosis. Males of N. anatolica sp. n. are very close to N. ripariensis , but easily separated from this species by the shape of the transparent membrane, nose-like bulging on tegulum and distinct embolus. The tibial apophysis of this species is slightly different from that of N. ripariensis as illustrated by Levy (1995) and Chatzaki (2002a), but the other palp structures are very different. In females, the epigynal plate resembles that of N. exornata and N. ripariensis but differs by the shape and size of the lateral contours of epigyne. In N. exornata the lateral contours of epigyne converge in with central depression, in N. ripariensis slightly separate but in N. anatolica sp. n. they are relatively separated and extended ( Figs 1–2).

Etymology. The specific name is an adjective referring to the country it was found.

Description. Male. Measurements (holotype): Body length 4.5; Carapace length 2.1; width 1.6; Abdomen length 2.4; width 1.5; length of legs: (I) 8.1, (II) 5.8, (III) 5.0, (IV) 7.7. Carapace nearly rectangular in shape, slightly narrowed in front; yellowish-brown with its upper parts lightly reticulated black; ocular area darker with few setae; cephalic area slightly elevated, its sides emphasized by black contours. Thoracic groove distinct in the middle. Anterior row of eyes nearly straight, posterior row slightly recurved in dorsal view; AME smallest, lateral eyes largest; PME oval, others nearly circular with black edges; lateral eyes slightly touching medians, but median eyes nearly separated from each other by their diameter. Chelicerae, labium and endites darker than carapace. Chelicerae with small fang and serrated carina retromarginally. Labium nearly triangular in shape. Endites rounded with swollen bases. Sternum nearly heart-shaped, same colour as carapace, bordered by thin black line, densely covered by hairs on margins. Abdomen yellow to brown, lighter on back with brown chevrons, and dark longitudinal bands on venter. Legs reddish-yellow. Patellae IV without setae. Leg formula 1423.

Male palp. Retrolateral tibial apophysis wide at base and protrudes outwards with peaked hump, ventral tibial apophysis lacking. Tegulum with nose-like bulging and its end with convoluted sperm duct. Median apophysis reduced. Transparent membrane elevated, its descending part elongated directly and its side with small protrusion. Embolus long, covered by a membrane in base, but only sclerotized and hook shaped at the tip ( Figs 3–6, 11–12).

Description. Female. As male, but larger body and slightly lighter in colour. Measurements: Body length 5.0–5.6; carapace length 2.1–2.5; width 1.6–1.9. Abdomen length 2.9–3.1; width 1.9–2.1; length of legs: (I) 5.9–7.0, (II) 5.1–5.7, (III) 4.8–5.3, (IV) 7.0–7.6. Leg formula 4123.

Epigyne. Heart-shaped, lateral contours very wide. Spermathecea and its ducts evident, spermathecae circular, ducts curved ( Figs 7–10).
