DESCRIPTION. Body length in males 11.8–12.5 mm, width 3.7–3.8 mm, body length in female 11.4 mm, width 3.8 mm. Body totally black, including antennae and legs, densely covered with yellow-brown pubescence.

Head with dense erect pale setae (longer in males) and dense light-brown recumbent pubescence (denser in males); frons transverse; genae relatively short, about two times narrower than lower eye lobe; the distance between upper eye lobes about two times more than width of 1st antennal joint; lower and upper eye lobes connected by very narrow bridge of about three ommatidia width; mandibles unicuspid.

Antennae thin, reaching elytral fifth in males or a little shorter in female; dorsally and ventrally with fine recumbent yellow-brown pubescence, with single short erect setae on 1st

joints; antennal joints 3–4 with small apical swellings; 1st joint nearly cylindrical; 1st joint about as long as 4th; a little longer than 3rd; 5th joint and others much shorter.

Prothorax strongly transverse, in males about 1.4 times wider (near middle) than long, in female – a little wider; pronotum convex, with two small flat central callosities, which can be totally covered (holotype) by dense recumbent light-brown pubescence evenly distributed all over pronotum also covered with dense long pale erect setae; small glabrous spot can be visible in the middle of posterior pronotal border; in female pronotal pubescence strongly reduced near anterior lateral angles; scutellum transverse, with dense recumbent pale pubescence.

Elytra flat, with sides converging posteriorly in males and female about 2.2–2.3 times longer than basal width in males, or about 2.2 times in female; no costae or longitudinal depressions present; light-brown very dense even elytral cover, totally hiding punctation presents; sparse short pale erect setae present near elytral bases in males; curved elytral margin black, without pale pubescence with exception of small light spot anteriorly; elytral apices truncated; apical elytral angles hardly pronounced.

Legs with very dense light-brown pubescence; posterior tibiae with long pale erect setae;

1st joint of posterior tarsi shorter than 2nd and 3rd combined; 3rd joint of posterior tarsi about as wide as long; denticles of tarsal claws narrow, but apically rounded; posterior coxae in males with short spines.

Metepisternae with same pubescence as elytra, but slightly reduced along ventral margin;

ventral body pubescence a little sparser than dorsal.

Pygidium in males truncated, postpygidium and last abdominal sternite with small emargi-

nations; in females last abdominal tergite with shallow emargination, last abdominal sternite truncated.

DIFFERENTIAL DIAGNOSIS. The new species is similar to Phytoecia (Musaria)

faldermanni Faldermann, 1837. It looks like m. blessigi Morawitz, 1863 ( Fig. 13 ) with densely pubescent pronotum and bright orange-yellow elytra, but distinctly wider (males of et Skrylnik, sp. n.; 2, 3 – C. kareli Danilevsky, 2018: 2 – type locality, 3 – locality of a female (paratype); 4 – C. rubenyani Danilevsky, 2018 , type locality; 5 – C. farsensis

Ph. faldermanni about 2.4 times longer than wide), pronotum more convex and wider; besides

Ph. faldermanni usually has partly red head, antennae, legs and abdomen; light spot in the anterior part of epipleurae much bigger; black stripes along epipleurae more or less reduced;

spines of posterior coxae in males rather long; denticles of tarsal claws needle-like.
