same locality, 13.4.2018, 1 ♂, leg. O. Pak – [ OP] ; same locality, 18.5.2019, 4 ♂ , leg. O.

♂, leg. I. Plyushch [ IP] .

DESCRIPTION. Body length in males 10.5–11.8 mm; width (at elytral middle) 4.1–5.0

mm; body length in females 13.1–14.0 mm; width (at elytral middle) 5.5–6.0 mm. Body usually black, or partly red or reddish.

Head in males often with reddish vertex. Antennae black, or in males black with reddish

1st joint, or red with darkened apical joints.

Prothorax in males red, reddish or black; head, antennae and prothorax in females always black; lateral thoracic spines very short, in males often totally obliterated; in females always levsky et Skrylnik, sp. n. in Tehran province; 18 – dorsal view of a male of D. olegpaki in nature; 19 – copulating pare of D. olegpaki ; 20 – biotope of Phytoecia plyushchi Danilevsky et Skrylnik , sp. n. in Gilan province [Rudbar County, 3km NE Damashvill., h= 2023 m,

distinct and acute; pronotum in males always glabrous and shining, with sparse irregular punctation (dots big or small, sometimes conjugated or contrary rather distant with wide shining areas in between), in females - densely pubescent, hiding or not completely hiding moderately big sparse punctation; pronotal central white line nearly totally reduced, hardly pronounced or indistinct, in females – absent.

Elytra in males about 1.8 times longer than wide, in females – about 1.6 times; male elytra evenly black, each with 3 contrast narrow white stripes; marginal stripe usually not wider or a little wider than epipleurae, one male with wide marginal stripe having irregular margin;

humeral stripe narrow, usually widely interrupted near middle, or with more or less numerous black spots; sutural white stripe about as wide as humeral; in females (only autochromal females known) ground elytral pubescence light-brown; more or less developed dorsal velvety black stripes always present, usually partly reduced apically.

DIFFERENTIAL DIAGNOSIS. The new species is very similar to D. cingulatoides

Breuning, 1946 described from Mazandaran ( Fig. 21 , 20 –26) and redescribed by Danilevsky

(2010b) because of similar pronotal and elytral design in males and females, but D.

cingulatoides usually bigger, lateral thoracic spines never obliterated, pronotum smaller;

body (including head, antennae and prothorax) can be totally bright-red; females can be androchromal; humeral white stripes very rare with black dots and never interrupted; body length in males 12.0–14.0 mm; body length in females 12.0–15.0 mm.

HABITAT. The species was observed in mountain humid valley along desert slopes with

Artemisia sp. , Astragalus sp. , Euphorbia sp. , Cousinia sp. at the level of 2100–2300 m above the level of the sea. All imagoes were collected under the stones.

DISTRIBUTION. Iran: north-east of Tehran province ( Fig. 21 , 19 ).

ETYMOLOGY. The new species is dedicated to a very lucky Donetsk collector Oleg

Pak, who collected a part of the type series.
