Zodarion imroz   spec. nov.

( Figs 1–7 View FIGURES 1–5 View FIGURES 6–7 )

Type material. Holotype ♂, Turkey, Gökçeada Island , 15.07.1993, Petar Beron leg. (NMNHS, ARA-Z.0005.1).  

Etymology. Named after Imroz, which is one of the old names for Gökçeada Island; name in apposition.

Diagnosis. The new species belongs to the Z. thoni   species-group. A close relationship to Zodarion beroni Komnenov & Chatzaki, 2016   is recognized by the smaller size, the presence of a dorsal scutum on the abdomen and the bifurcated apical part of the embolus. The two species can be separated by the following characters: (1) Z. imroz   spec. nov. with rectangular MA ( Figs 4 View FIGURES 1–5 , 6 View FIGURES 6–7 ) whereas MA of Z. beroni   is more irregularly shaped. (2) Z. imroz   spec. nov. with characteristically twisted PMA, with triangular end, situated near the embolic base ( Figs 4 View FIGURES 1–5 , 6 View FIGURES 6–7 ), while Z. beroni   with leaf-shaped PMA, positioned higher ( Komnenov et al. 2016, fig 105–106). (3) Z. imroz   spec. nov. with embolus longer and situated much higher above the MA ( Figs 4 View FIGURES 1–5 , 6 View FIGURES 6–7 ) than in Z. beroni   .

Description. Holotype male ( Figs 1–7 View FIGURES 1–5 View FIGURES 6–7 ). Measurements. Total length 2.12; carapace length 1.08, width 0.75; sternum length 0.58, width 0.50; chelicerae length 0.42, width 0.20; clypeus height 0.16; cymbium length 0.45; eye diameters: AME 0.09, ALE 0.06, PME 0.05, PLE 0.05; abdomen length 1.04, width 0.68; leg I—2.95 (0.36, 0.72, 0.29, 0.54, 0.54, 0.50), leg II—2.53 (0.29, 0.58, 0.25, 0.47, 0.47, 0.47), leg III—2.38 (0.32, 0.45, 0.25, 0.43, 0.50, 0.43), leg IV—(0.40, 0.90, 0.30, -, -, -). The last 3 segments of the leg IV missing.

Colouration. Carapace orange to light brown, smooth and shiny, lighter in anterior part, with dark brownishgray pattern posteriorly ( Fig 1 View FIGURES 1–5 ). Anterior eye row region black. Fovea dark brown. The margin of the carapace bordered with narrow brownish-gray strip. Legs and sternum orange, a little lighter than the carapace. Chelicerae the same color as carapace. Palpal segments the same color as the legs. Dorsal scutum of the abdomen brown, with metallic glint and faint darker pattern ( Fig 2 View FIGURES 1–5 ). Ventral side of abdomen yellowish in centre, darker in anterior and posterior ends ( Fig 3 View FIGURES 1–5 ). Colulus pale orange. Spinnerets white.

Other somatic characters. Posterior eye row strongly recurved. AME much larger than the other eyes. Distance PME-PME 0.13. ALE and PLE close to AME, distance 0.02. Distance AME-AME 0.02. Chelicerae with opistognathic position. Femoral organ with 3 or 4 setae. Abdomen oval, with 2 spinnerets and dorsal scutum covering its whole length. Colulus represented by a broad, narrow hairy plate.

Palp ( Figs 4–7 View FIGURES 1–5 View FIGURES 6–7 ). RTA notched dorsally in distal part, with sharp black tip ( Figs 5 View FIGURES 1–5 , 7 View FIGURES 6–7 ). Bulbus oval. Embolus long and thin, starting approximately at 8 o’clock and ending at 2 o’clock, apical part forked. MA large, rectangular with characteristically twisted prolateral process with triangular prolaterad end ( Figs 4 View FIGURES 1–5 , 6 View FIGURES 6–7 ).

Female unknown.

Distribution. Known only from the type locality ( Fig 16 View FIGURE 16 ).

Remarks. Although Z. imroz   spec. nov. is described from only one male specimen, it is highly unlikely to be the unknown male of an already described species, having in mind that there are no Zodarion   species known only by females from Turkey. Also, none of the two Greek species known only by females belongs to Z. thoni   -group.
