Holotype ♀ ( HMIM ): Ghasr-e Shirin to Sarpol-e Zahab road, 15 km E Ghasr-e Shirin , 34°27'57"N 45°45'36"E , 460 m , 25.V.2007 , leg. Nasserzadeh , Zahiri , Montreuil [sclerite plate of bursa copulatrix and the last abdominal sternite mounted in euparal on transparent card]. Diagnosis . Similar to D. mesopotamicus Platia & Gudenzi, 1999 , distinguished by uniformly darker color, sides of pronotum dilated in anterior third and bursa copulatrix sclerite plate. Description . Female: coloration dark, uniform without distinct marks, head rather rufo-piceous, pronotum rufous and elytra rufous to rufo-testaceous, rather testaceous apically; head, pronotum, around of scutellum, with blackish shadings, elytra with rufo-piceous shadings marginally; antennae and legs testaceous; covered with dense, short, recumbent, yellowish pubescence. Frons moderately convex, feebly impressed at the anterior margin, the latter edged, sub-arcuate and just protruding above the clypeus. Right antenna is missing and the left one is broken at the seventh article; second article subconical, twice as long as wide, serrated from third article on. Pronotum widest at anterior third, 1.1 × wider than long, strongly and regularly convex, abruptly sloping at sides and base; sides arcuate, strongly converging from mid-length to base and just sinuate before to the posterior angles, the latter short, truncate, slightly divergent with a short carina; punctuation double, distributed uniformly; larger, deep, simple punctures are regularly mixed with fine, dense and nearly contiguous punctures. Scutellum heart-shaped, as long as wide, slightly impressed at center, finely punctured. Elytra 2.3 × longer than pronotum and as wide as it or slightly wider, convex and ovaliform, widest posteriorly, just before mid-length; striae well-marked and deeply punctured for all their length; interstriae moderately convex, very finely punctured. Apical margin of last abdominal sternite ( Fig. 7 ) rather straight. Claws dentate at base. Sclerite plate of bursa copulatrix with four large spines in a row in the middle as in the fig. 6. Male: unknown. Size: Length 7.1 mm ; width 2.2 mm . Etymology . The name is derived from the country in which the holotype was collected, Iran . Habitat. In loose soil in vegetated area.
