Type-locality. The Dim cave is situated 11 km. from the Alanya on the road to Dim River (Antalya Province). The cave is at a height of 232 meters above sea level and on the western slope of Cebel Reis Mountain.

Material examined. Holotype male. Turkey, Antalya, Alanya, Dim cave, 36o32’405’’ N; 32o 06’549’’ E, 232 m, 30.08.2009, M.S. Taylan, Ş.B. Taylan, S. Tan leg.

Paratypes: 4 males, 6 females, 1 nymph, same date and collectors; 2 male, 1 female, 6 nymphs same locality, 16.12.2007, M. Rampini and C. Di Russo leg.

Diagnosis. The new species is close to T. gajaci but it differs from it and from all the other known species by the reddish brown body coloration the typical white thoracic stripe and the curved shape of ovipositor from basal to apex. The size is relatively small with the hind legs briefly elongated. The male tenth tergite shows two rounded lateral lobes separated in the middle, by a large concavity. In the female the subgenital plate is trapezoidal almost restricted with two rounded lobes on the posterior margin.

Description. Male (holotype). Size relatively large (17.0 mm); colour reddish brown, with all the tergites finely spotted. Thorax with an evident median white line. Legs rather elongated, fore and mid femora unarmed.

Hind femora armed with 3–5 spines on the inferior edge. Fore tibia bears 7–11 spines on both sides of the inferior edge. Mid tibia with 10/11 spines on both sides of the lower edge and 5 short spines on the upper edge. The hind tibia is longer with about 80 spines of varying length on both sides of the upper edge and 25–27 homogeneous spines on the lower edge. First article of hind tarsum laterally compressed and armed with 13 strong spines. Tenth tergite ( Fig. 1 ), on the posterior edge, with two rounded lateral lobes separated in the middle, by a large concavity. Subgenital plate ( Fig. 2 ) trapezoidal rather globular, the posterior edge show a moderate concavity slightly incised holding two prominent conical styli. Copulatory apparatus membranous.

Measurements. (in mm): body 17.0; pronotum 5.0; fore femur 8.6; middle femur 7.3; hind femur 16.8; fore tibia 9.0; middle tibia 8.5; hind tibia 19.6; hind tarsus 7.0; 1st article of hind tarsus 4.0.

Female. The length of the body ranges from 19 and 20 mm (ovipositor excluded) and the general form of the female is similar to the male. The subgenital plate ( Fig. 3 ) is trapezoidal almost restricted, with two evident rounded lobes at the posterior edges. The ovipositor has an average length of 11 mm, rather enlarged at the base and little curved on the superior edge ( Fig. 4 ). The superior valves have a pointed apex and curves upwards, whereas the inferior valves are narrow and scleritized bearing 12–13 strong denticles.

Etymology. The new species takes its name for Alanya County (Antalya district), Turkey.
