Type-locality. The Güroluk cave is situated in Güroluk area, in the Fethiye Gökçeovacık Village, (Muġla Province). The cave is at a height of 450 m above sea level and located on the western slope of Kızıldaġ Mountain.

Material examined. Holotype male: Turkey, Muġla, Fethyie, Gökçeovacık, Güroluk cave, 36o47’564’’ N; 28o58’646’’ E, 450 m, 26.06.2008, M.S. Taylan, Y Dikmentepe leg.

Paratypes: 1 male, 4 females, same date and collectors; 1 male, Turkey, Muġla, Milas, Uyku vale, Gökçeler cave, 37o11’378’’ N; 27o45’982’’ E, 120 m, 25.11.2008, E. Özel leg.

Diagnosis. Troglophilus fethiyensis differs from T. alanyaensis by the male tenth tergite which is transverse and with posterior margin straight and in the large almost square subgenital plate of the female. The ovipositor has a typical shape with the superior valves pointed at apex and curved upwards, whereas the inferior valves are narrow.

Description. Male (holotype). Size relatively large (18.9 mm); colour brown, with all the tergites finely spotted. Legs rather elongate, fore and mid femora unarmed. Hind femora with 4 short spines on the ventral margin. Fore tibia with 8/10 spines on both sides of the ventral margin. Mid tibia with 8/10 spines on both sides of the ventral surface and 1/3 short spines on the dorsal surface. The hind tibia is longer with less than 70 spines of varying lengths on both sides of the dorsal surface and 33–34 homogeneous spines on the ventral margin. First article of hind tarsus laterally compressed and armed with 10 strong spines. Tenth tergite ( Fig. 5 ) transverse with the posterior edge almost straight showing a narrow concavity in the middle. Sub-genital plate ( Fig. 6 ) trapezoidal rather globular, at the bottom. The posterior edge moderately corrugated holds two short conical styli. Copulatory apparatus membranous.

Measurements. (in mm): body 18.9; pronotum 4.0; fore femur 8.9; middle femur 7.9; hind femur 14.9; fore tibia 9.9; middle tibia 9.0, hind tibia 18.0; hind tarsus 6.3; 1st article of hind tarsus 3.2.

Female. The length of the body ranges between 17 and 18 mm (ovipositor excluded) and the general form of the female is similar to the male. The subgenital plate is large almost square ( Fig. 7 ), with two evident rounded lobes separated by a large concavity. The ovipositor has an average length of 9 mm; at the bottom the lower edge appears strongly curved ( Fig. 8 ). The superior valves have a pointed apex and curves upwards, whereas the inferior valves are narrow and sclerotized showing 13–14 strong denticles.

Etymology. The new species takes its name from Fethiye Province (Antalya district), Turkey.
