Type material.

Holotype ♂ (ZMUT), Iran: Hormozgan Province: Siahu, 27°45'N, 56°20'E, 02.2018 (A. Zamani). Paratypes: 1♀ (ZMUT), same data as the holotype; 1♂ (MMUE), Fars Province: Shiraz, inside house, 29°37'N, 52°30'E, 6.05.1982 (P. Hassanzadeh); 1♂ (MMUE), Shiraz, garden, 29°37'N, 52°30'E, 04.1982 (P. Hassanzadeh); 1♂1♀ (MMUE), Shiraz, inside house, 29°37'N, 52°30'E, 06.1982 (P. Hassanzadeh); 1♀ (ZMUT), Hormozgan Province: Siahu, 27°45'N, 56°20'E, 02.2020 (A. Zamani); 1♀ (ZMUT), Siahu, palm orchards, 27°45'N, 56°20'E, 02.2020 (A. Zamani).

Etymology.

The specific epithet is an adjective and refers to the country from where the specimens of the new species were collected.

Diagnosis.

The male of the new species is somewhat similar to that of D. arabica Deeleman-Reinhold, 1988 from Oman (cf. Fig. 8A-D and Deeleman-Reinhold and Deeleman 1988: figs 309-310), but differs by the small, claw-like posterior apophysis (vs. broad and rounded) and keel-like median crest (vs. rounded). The male of D. iranica sp. nov. differs from those of its congeners occurring in Iran by the elongate keel-like median crest (vs. rounded or triangular). The female of D. iranica sp. nov. is most similar to that of D. tapuria sp. nov. by having a very wide receptacle (i.e.,> 2 × wider than the transverse bar), but differs by having a triangular extension (Te) in the anterior margin of the receptacle (vs. absent).
