description: Dysdera goyzha Zamani & Marusik, sp. n.
Figs 4A–B, 5A–D, 6D
Type material. Holotype ♂ (ZMUT), IRAQ: Sulaymaniyah Governorate: Goyzha Mt., Hawary Shar Park, 35°37‘27.1“N 45°27‘28.8“E, 08.03.2022 (F.A. Khudhur). Paratypes: 1♂ 2♀ (ZMUT), same as for the holotype.
Etymology. The specific epithet is a noun in apposition, referring to the type locality of the new species.
Diagnosis. The male of the new species is somewhat similar to that of D. tapuria Zamani, Marusik & Szűts, 2023 from Iran, in having a low, poorly sclerotized crest (C), but it differs by the lack of a stylus (cf. Fig. 5A and Zamani et al. 2023: fig. 30A). Dysdera goyzha sp. n. differs from all congeners in having a large retrolateral lamina (Rl) forming a claw- or bill-like shape in dorsal and ventral views (Fig. 5C, D). The female of the new species differs from all congeners by having a ragged anterior surface of the receptacle (Re; Fig. 6D).
Description. Male (Holotype). Habitus as in Fig. 4B. Total length 10.83. Carapace 4.00 long, 3.20 wide. Eye diameters: AME 0.22, PME 0.16, PLE 0.18. Carapace, sternum, chelicerae, labium, and maxillae light reddish brown. Legs light orange. Abdomen beige, without any pattern. Spinnerets uniformly beige. Measurements of legs: I: 14.47 (4.00, 2.44, 3.50, 3.62, 0.91), II: 13.44 (3.78, 2.17, 3.21, 3.40, 0.88), III: 10.31 (2.95, 1.63, 2.10, 2.83, 0.80), IV: 12.90+missing Ta (4.11, 2.06, 2.95, 3.78, missing).

Palp as in Fig. 5A–D; cymbium long, 3.5 times longer than wide; bulb attached to cymbium in proximal half; bulb ca. 1.6 times longer than cymbium, and 3.3 times longer than wide; tegular part 1.2 times longer than wide; psembolus longer than tegulum, with weakly sclerotized and low crest (C) and large retrolateral lamina (Rl), proximal part of lamina bent toward cymbium.
Female. Habitus as in Fig. 4A. Total length 12.63. Carapace 4.65 long, 3.32 wide. Eye diameters: AME 0.22, PME 0.17, PLE 0.19. Coloration as in male. Measurements of legs: I: 15.15 (4.24, 2.82, 3.55, 3.49, 1.05), II: 14.75 (4.20, 2.45, 3.43, 3.62, 1.05), III: 11.31 (3.32, 1.80, 2.26, 2.98, 0.95), IV: 15.45 (4.54, 2.27, 3.30, 4.27, 1.07).
