Figs 5A-C , 6A, B Type material. Holotype ♀ (ZMUT), Iran: Hormozgan Province: Hormuz Island, 27°02'N , 56°29'E , 01.2014 (A. Zamani). Etymology. The specific epithet is an adjective referring to Hormuz Island, from where the holotype was collected. Diagnosis. The new species differs from all Dysdera species occurring in the region by the receptacle divided into two chambers (vs. undivided), and the indistinct dorsal arch (vs. distinct). Description. Female. Habitus as in Fig. 5A-C . Total length 8.11. Carapace 3.26 long, 2.56 wide. Eye diameters: AME 0.13, PME 0.13, PLE 0.14. Carapace, sternum, chelicerae, labium, and maxillae orangish. Legs pale orange. Abdomen pale cream-coloured, without any pattern. Spinnerets uniformly pale cream-coloured. Measurements of legs: I: 7.87 (2.19, 1.29, 2.01, 1.85, 0.53), II: 7.31 (1.99, 1.19, 1.77, 1.83, 0.53), III: 5.83 (1.61, 0.88, 1.13, 1.74, 0.47), IV: 7.27 (1.83, 1.05, 1.56, 2.22, 0.61). Spination: I: Fe: 2pl. II: Fe: 3pl. III: Fe: 3d; Pa: 1d, 1pl; Ti: 5pl, 2rl, 6v; Mt: 3d, 6pl, 2rl. IV: Fe: 8d; Pa: 1pl; Ti: 5pl, 3rl, 6v; Mt: 3pl, 4rl, 3v. Figure 5. Female of Dysdera hormuzensis sp. nov., habitus A dorsal view B ventral view C lateral view. Scale bars: 1.0 mm. Endogyne as in Fig. 6A, B ; length/width ratio ca. 2.6; receptacle 2 x longer than wide, divided in two chambers, with an anterior median concavity; anterior angles located almost at mid-part of each chamber and directed anteriorly, approximately as long as wide; dorsal arch indistinct; transverse bar ca. 4.6 x longer than wide, mid-part similar to an inverted trapezoid, anterior part 1.3 x longer than posterior part; lateral edges directed postero-laterally, clearly separated from transverse bar by an incision; posterior diverticulum elongated horizontally. Figure 6. Female of Dysdera hormuzensis sp. nov., endogyne A ventral view B dorsal view. Scale bars: 0.25 mm. Male. Unknown. Comments. The species group (or even generic) assignment of this species is tentative pending the collection of the corresponding male. Distribution. Known only from the type locality in Hormuz Island, the Persian Gulf (Fig. 35 ).
