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 ).
