MATERIAL EXAMINED. Iran: Āzarbāyjān-e Gharbī, Jaldian env., Nagadeh , h= 1500 m ,

16.4.1996, 3 ♂, 1 ♀, leg. W. Heinz [ MD]; Iran: Āzarbāyjān-e Gharbī, Pass zw. Mahabad u .

Pasweh, h= 1400–2000 m, 16.4.1991, 5 ♂, leg. W. Heinz [ MD]; Iran: Āzarbāyjān-e Gharbī ,

pass 16 km SWW Nagadeh (S Orumiye), 16.4.2002, 3 ♂, 2 ♀, leg. P. Kabatek [ MD] .

DESCRIPTION. Body length of available males 9.5–12.3 mm; body length of available females 10.8–13.1 mm. Body relatively small.

Antennae more or less red with darkened apical joints, sometimes rather dark with reddish

1st joint.

Prothorax usually with obliterated lateral spines; pronotum often poorly pubescent,

sometimes nearly glabrous in fresh specimens, in males pronotal punctation never totally hiding by pubescence; dorsal ground pubescence in males black, in females – brown (darker or lighter); narrow white central pronotal line always distinct.

Elytra in males with even black pubescence, without velvety black longitudinal stripes,

but sometimes with small brownish apical areas; elytra in females brown with a pair of very contrast velvety black irregular dorsal stripes, many times interrupted; sometimes short parts of dorsal black stripes can be replaced by fine white pubescence; humeral white stripes with or without numerous black spots.

Legs red (darker or lighter).

DISTRIBUTION. As far as Iranian populations are conditionally accepted here as being conspecific to Turkish Diarbekir population following a generally accepted opinion by Breuning (1958, 1962), the species can be distributed along eastern Anatolia to Iranian border.

Four localities are definitely known in North-West Iran in south-west of Āzarbāyjān-e Gharbī province: Jaldian env., Nagadeh , 1500 m (about 36°51'42"N, 45° 8'47"E), Pass zw. Mahabad u. Pasweh, 1400–2000 m (about 36°44'30"N, 45°31'59"E), pass 16km SWW Nagadeh

(about 36°54'15"N 45°12'50"E), Piranshahr environs (about 36°41'28"N, 45°6'43"E) ( Fig.

21, 14–17 ).

REMARKS. The species is very close to Dorcadion cingulatum and represents its northern vicariant. A species with even black elytral pubescence (without velvety black dorsal stripes)

distributed in Āzarbāyjān-e Gharbī was wrongly accepted by Bernhauer (2015, though the locality of depicted specimens was not published here) as D. cingulatum . That incorrect conception was shown by several internet publications (Danilevsky, 2011; Kasatkin, 2015;

Hoskovec et al., 2020). No correct names were proposed for those populations. I don’t like to describe this form as a new species now, as the status of the nearest Turkish population traditionally attributed to D. cingulatum is not clear. It was described as D. invicinum Pic,

1902b on the base of a single female from Diarbekir. Now I provisionally attribute the name

D. invicinum Pic , stat. ressur. to the populations from Āzarbāyjān-e Gharbī.

Dorcadion kharpuensis Danilevsky, 1998 (described from Gilan; Fig. 21 , 18 ) was compared with “ D. cingulatum ” from Āzarbāyjān-e Gharbī in the original description. So, in fact it was compared with D. invicinum . But D. kharpuensis differs from both D. cingulatum and

D. invicinum by glabrous shining pronotum in males. So, D. kharpuensis is close to neighbor

D. cingulatoides Breuning, 1946 distributed in Mazandaran ( Fig. 21 , 20 –26), but latter is usually bigger and wider, with usually red prothorax and head, thicker antennae.
