description: Zodarion namrun n. sp.
Figs 15–17, 19–20
Type material. ♂ holotype, Turkey, Taurus Mountains, Mersin province, Çamlıyayla, Namrun Castle, pine forest, 05.06.1964 (NMW).
Etymology. Named after the Namrun castle, the type locality of the species; noun in apposition.
Diagnosis. The species belongs to Z. thoni group (sensu Bosmans 2009), judging from the large, rectangular median apophysis of the male palp with the typically twisted distal processus (Figs 16, 19). The male differs clearly from all the other species in the group by the shape of the embolus—long and thin, ending with needlelike unmodified tip (Figs 16, 17, 19, 20) vs. ending with different modifications in Z. thoni (Fig 5), Z. reticulatum, Z. rhodiense, Z. beroni and Z. imroz or truncated in Z. granulatum (Fig 18). Also, the new species differs by the broad and rectangular distal extension of the median apophysis (Figs 16, 19) vs. with narrower tip in all the other species.
Description. Male (Figs 15–17, 19–20). Measurements. Total length 4.04; carapace length 2.04, width 1.44; sternum length 1.04, width 0.80; chelicerae length 0.69, width 0.36; clypeus height (measured under the AME) 0.24; cymbium length 1.04; eye diameters: AME 0.11, ALE 0.06, PME 0.5, PLE 0.06; abdomen length 2.00, width 1.33; leg I—7.17 (0.78, 1.74, 0.58, 1.43, 1.64, 1.00), leg II—6.48 (0.67, 1.59, 0.55, 1.17, 1.53, 0.97), leg III—6.45 (0.73, 1.56, 0.55, 1.05, 1.73, 0.83), leg IV—9.00 (1.03, 2.13, 0.61, 1.80, 2.39, 1.04).
Colouration. Carapace dark brown with almost black margins and ocular area, smooth and shiny, with well visible black fovea and darker perpendicular stripes (Fig. 15). Legs with brown femora, slightly lighter than the carapace. Other leg segments yellow. Sternum light brown. Chelicerae and palpal segments the same color as carapace. Dorsal abdominal scutum black, with a metallic glint, without a pattern (Fig. 15). The rest of the abdomen brown, with a white spot ventrally, another (smaller one) posteriorly, above the spinnerets, and a diagonal white stripe on each side. Colulus well visible, light-brown. Spinnerets yellowish with light-brown bases. AME twice larger than the other eyes. Chelicerae with opistognathic position. Femoral organ with 3 or 4 setae. Abdomen with 2 spinnerets and dorsal scutum, not covering its whole length. Colulus represented by a broad, narrow hairy plate.
Palp (Figs 16–17, 19–20). RTA elongated, curved distally, with pointed tip. Bulbus oval, elongated. Embolus long and thin, starting approximately at 8 o’clock position and ending at 4 o’clock. The tip of the embolus thin, unmodified. MA large, shaped as an irregular rectangle, with characteristically twisted distal extension (Figs 16, 19).
Female unknown.
Distribution. Known only from the type locality in the Taurus Mountains (Namrun), Turkey.
