( Figs 2D–F , 9B , 10B , 11B , 12B , 13B )

For a full bibliography for records from Iran and the Caucasus see in Abdurakhmanov & Nabozhenko (2011).

Type material. Syntypes of Ménétriés (1832) and Faldermann (1837) were not traced in ZIN. The species was described from “Zouvand” (now Azerbaijan, Talysh Mts , Zuvand ). This is the only species of Dendarus which occurs in East Azerbaijan .

Material (listed only from Iran and Turkmenistan). Iran. 1♀ ( HNHM): Zanjan Prov., Elborz Mts, Zangan Talesh Mt., 2000 m, 6.vi.1999 (leg. K. Gaskó, T. Hácz & G. Köszegi). Turkmenistan. 1♂ ( ZIN) Kara-Kala, 1966 (leg. V. Potapol’skiy) ; 2♂♂ ( ZIN): Kopetdag, Bakharden, 1966 (leg. V. Potapol’skiy) .

Diagnosis. Male. Body shiny, robust. Head and pronotum with coarse and dense uniform puncturation of round punctures (puncture diameter slightly longer or subequal to interpuncture distance). Head ventrally with simple (not impressed) longitudinal furrow beyond prementum. Pronotum weakly convex. Lateral margins of pronotum widely emarginated at basal quarter; anterior angles weakly protruding; base deeply bisinuate, posterior angles acute, strongly protruding beyond base of pronotum. Prosternal process comparatively narrow, narrowly rounded at apex. Elytra widest at middle. Strial punctures large, strongly elongate, sparse (19–22 punctures in one row), located each in deep wide impression, much larger than interstrial ones. Interstriae convex or sometimes carinate, with dense and fine puncturation. Protibiae wide, with shallow notches to the inner side and widely rounded, obtuse angles before the indentations; protibia widest at apex. Mesotibiae very weakly bending inwards. Mesotarsomeres 1–4 widened, tarsomeres 1–3 with full hair brush on sole.

Female. Body more robust, protibiae weakly bent.

Distribution. Turkey, Transcaucasia, the North Caucasus ( Russia: Dagestan, Chechen Republic), Iran ( Abdurakhmanov & Nabozhenko 2011), Turkmenistan (new record for the country).
