diagnosis
Diagnosis. The male of the new species is somewhat similar to that of D. arabica Deeleman-Reinhold, 1988 from Oman (cf. Fig. 8 A-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 x wider than the transverse bar), but differs by having a triangular extension (Te) in the anterior margin of the receptacle (vs. absent).
distribution
Distribution. Known from the listed localities in Fars and Hormozgan provinces, south-central and southern Iran (Fig. 35).
etymology
Etymology. The specific epithet is an adjective and refers to the country from where the specimens of the new species were collected.
