Diagnosis.

Male palp of Kut izmiricus sp. nov. resembles those of K. troglophilus and K. dimensis sp. nov.; in Kut izmiricus sp. nov. the bulb is more slender and exceeds embolus in length, unlike in the other two species. Female of Kut izmiricus sp. nov. differs from others by having a longer midspermatheca.

Derivatio nominis.

The specific name is a toponym that refers to the type locality, İzmir Province.

Measurements

(Holotype ♂ / Paratype ♀). AL 6.56/5.80; CL 6.00/5.00; CW 4.32/3.60; AMEd 0.14/0.11; PLEd 0.08/0.10; PMEd 0.05/0.08; ChF 1.45/1.15; ChG 1.00/0.90; ChL 3.10/2.25.

Description.

Carapace reddish brown, with thick dark brown contours at the borders. Fovea distinct, longitudinal ( Fig. 2A View Figure 2 ). Carapace surface with tiny dents; these dents with tiny, black setae inside. These setae are longer in the cephalic region, especially around eyes. Eyes tiny, reduced. Distance between anterior eyes approximately 2.5 times their diameter. Posterior eyes spherical, slightly concave. Chelicera, gnathocoxa, and labium dark brown. The new species resembles K. troglophilus by the other cheliceral traits ( Fig. 2B View Figure 2 ). Sternum brown, covered with setae, and with dark brown contours at the borders. Sternum with eight dark brown blotches, symmetrically reaching from sides toward center. Gnathocoxae with yellowish setae prolaterally at tips ( Fig. 2B, C View Figure 2 ).

Legs brown. Coxae I, II and III darker in colour compared to other leg segments. See Tables 3 View Table , 4 View Table for details on leg measurements and spination. Abdomen slender, cylindrical, greyish cream in colour.

Palp ( Figs 2 D–F View Figure 2 ). Palpal tarsus shorter than tibia, conical. Tegulum exceeds embolus in length. First half of tegulum cylindrical, second half reversely conical. The anterior side of the tegulum smoothly straight. Embolus short and hook-shaped, bent posteriorly.

Vulva ( Fig. 2G, H View Figure 2 ). Midspermatheca club shaped, very long, its tip transparent and slightly bent posteriorly. Paraspermathecae short, spherical. Posteriorly to spermathecae, two horizontally aligned bars; among these, one closer to spermathecae is shorter, distant one twice as long and more chitinized.
