Type material.
Holotype ♂ (ZMUT), Iran: Tehran Province: Tehran, 35°43'N, 51°24'E, 1994 (A. Savoji).
Etymology.
The specific epithet is a noun in apposition, referring to an ancient Iranian people who inhabited an area known as Media between western and northern Iran.
Diagnosis.
The male of the new species is similar to that of D. granulata Kulczyński, 1897 from Italy and the Balkan Peninsula, but differs by the shape of the tegulum (i.e., almost as wide as long, vs. 1.5 × longer than wide), and by thinner psembolus (as wide as tegulum, vs. wider than tegulum). The male of D. medes sp. nov. differs from those of its congeners occurring in Iran by the very long median crest (i.e., longer than half of psembolus, vs. shorter), abrupt tip of psembolus in ventral and dorsal views (Fig. 28C, D View Figure 28 ) (vs. not abrupt), and posterior apophysis with two teeth (vs. one).
Description.
Male. Habitus as in Fig. 27A-C View Figure 27 . Total length 10.0. Carapace 4.19 long, 3.17 wide. Eye diameters: AME 0.14, PME 0.14, PLE 0.14. Carapace, sternum, chelicerae, labium, and maxillae reddish brown. Legs orange. Abdomen greyish, without any pattern. Spinnerets uniformly dark yellowish. Measurements of legs: I: 12.33 (3.54, 2.03, 2.89, 3.00, 0.87), II: 13.50 (3.80, 2.40, 3.12, 3.29, 0.89), III: 9.99 (2.95, 1.59, 1.86, 2.69, 0.90), IV: 12.31 (3.73, 1.80, 2.46, 3.30, 1.02). Spination: I, II: no spines. III: Ti: 4pl, 2rl, 5v; Mt: 6pl, 3rl, 2v. IV: Fe: 7d; Ti: 7pl, 4rl, 8v; Mt: 7pl, 3rl, 4v.
