Type material.
Holotype ♂ (ZMUT), Iran: Hormozgan Province: Geno Biosphere Reserve, 27°22'N, 56°07'E, 02.2020 (A. Zamani). Paratypes: 3♀ (ZMUT), same data as the holotype.
Etymology.
The specific epithet is an adjective, referring to the type locality of the species.
Diagnosis.
The male of the new species differs from those of its congeners by having weakly sclerotized bent stylus (St) (Fig. 32C, F View Figure 32 ) (vs. stylus, if present, not bent). The female of this species is very similar to that of D. iranica sp. nov. by having a wide receptacle (i.e.,> 2 × wider than transverse bar), but differs by the relatively wider receptacle lacking an anterior triangular projection, and the presence of a median concavity on the transverse bar (vs. receptacle with triangular projection, transverse bar without concavity).

Male (Holotype). Habitus as in Fig. 32A-C View Figure 32 . Total length 5.49. Carapace 2.42 long, 1.88 wide. Eye diameters: AME 0.15, PME 0.13, PLE 0.11. Carapace, sternum, chelicerae, labium, and maxillae pale reddish. Legs orange. Abdomen cream-coloured, without any pattern. Spinnerets uniformly cream-coloured.

Endogyne as in Fig. 34A, B View Figure 34 ; length/width ratio ca. 2; receptacle (Re) inverted trapezoidal, anterior margin 1.4 × longer than posterior; dorsal arch (Da) trapezoidal, posterior margin 1.6 × longer than anterior margin, 1.25 × longer than receptacle; anterior margin of transverse bar (Tb) with median concavity, posterior margin arched; lateral edges (Le) small, approximately as long as wide; posterior diverticulum (Pd) bilobed.
