Abstract: Dorcadion (Cribridorcadion) cinerarium demidovi ssp. n. is described from South-West Ukraine (Odessa environs). The new subspecies is close to D. c. gorodinskii Danilevsky, 1996 from Kherson Region because of pubescent male elytra, but differs by strong individual variability in color and body pubescence.
The detail revision of taxonomy structure of Dorcadion cinerarium (Fabricius, 1787) by M.A. Lazarev (2011) was limited in certain areas by the absence of enough number of available specimens. One of the worst investigated regions is South Ukraine along the coasts of Black and Azov seas. Five subspecies are already described from here: D. c. perroudi Pic, 1942 (most part of Crimean Peninsula), D. c. panticapaeum Plavilstshikov, 1951 (the east of Crimean Peninsula from about Kerch to Chongar), D. c. bartenevi Lazarev, 2011, (the west of Crimean Peninsula, cape Tarkhankut), D. c. azovense Lazarev, 2011 (Berdyansk environs), D. c. skrylniki Lazarev, 2011 (Melitopol environs) and D. c. gorodinskii Danilevsky, 1996 from Kherson environs. The populations from Nikolaev to Odessa and South Moldova were provisionally included in D. c. gorodinskii because of moderately big size and pubescent male elytra, though only single specimens were available from about 7 localities.
A collecting trip of the author in April 2013 to Odessa environs allowed obtaining a representative quantity of beetles for study. Invaluable materials were also received from local collectors Larisa Ladovyrya and Grigoriy Demidov, who collected the most number of available specimens. New materials show the unique level of the individual variability inside Odessa populations, which is impossible in D. c. gorodinskii. So, a new subspecies must be described.
Now the subspecies status of populations from Chongar, Mariupol and Taganrog needs clarification.

Dorcadion (Cribridorcadion) cinerarium demidovi ssp. n.
(Figs. 1-9)
Description. Antennae black with dark-red 1st joint, sometimes 1st joint nearly or totally black (Fig. 2), very rare light-red (Figs 5-7); prothorax in males from about as long as basal width to slightly transverse, about 1.1 times wider than long; in females about 1.3 times wider than long; pronotum slightly convex, smooth, with shallow longitudinal impression; in males sometimes with two posterior rugose areas (Fig. 3), always nearly glabrous, shining with more or less dense short black recumbent setae, which can be indistinct; with narrow central white stripe distinct in fresh specimens; in females - totally pubescent with wider longitudinal white stripe; pronotal punctation fine, consists of small scattered dots and very fine dense punctation; lateral thoracic tubercles short, rounded; male elytra usually totally or partly covered with black pubescence, which can be easily lost along slightly convex longitudinal ridges (Fig. 5); elytra regularly oval, widest near middle, in males about 1.8-1.9 times wider than long, in females - 1.5-1.6 times; male elytral pubescence is distinctly less solid than in males of D. c. gorodinskii, many fresh males have shining glabrous elytral areas along lateral half; about one third of all males in all populations has glabrous shining elytra (Figs. 4, 6) in all populations, that is impossible in D. c. gorodinskii; pubescent male elytra usually with small white spots anteriorly, very rare fine traces of humeral white stripes can be visible (Fig. 2), as well as apical white spots; bright sutural white stripe is always accompanied by velvety black stripes;
all females are authochromal with very dense ground elytral pubescence, which is usually dark-brown (Fig. 8) or a little lighter (Fig. 9), but in general much lighter than in D. c. gorodinskii; external pale elytral stripes more or less distinct, usually interrupted by more or less numerous dark spots; dark pubescence along white sutural stripes usually interrupted or split in several dots; legs usually dark-red; femora sometimes nearly black (Fig. 1), but lightened at bases, never totally black, often red with small black areas (4-5); very rare legs purely red (Figs. 6-7); body length in males: 10.7-13.5 mm; width: 3.8-4.7 mm; body length in females: 11.0-14.0 mm; width: 4.6-5.7 mm.
Note. D. (C.) c. demidovi ssp. n. is geographically and morphologically close to its eastern neighbor D. c. gorodinskii Danilevsky, 1996, but differs by less pubescent elytra, which can be often totally glabrous (with the exception of sutural lines); legs and 1st antennal joint can be puerly red; females are in general lighter. Its north neighbor D. c. zubovi Lazarev, 2011 from Moldova is rather different because of the domination of glabrous males and females in all populations.
Distribution. South-West Ukraine: several localities are known along coasts of Odessa limans: Khadzhibey, Kuyalnik (Fig. 10), Adzhalyk. The taxon is also known from the south of Nikolaev Region: Ochakov environs, Novaya Bogdanovka, Nikolaev environs, Parutino in Bug liman coast. The locality near Purkary in Moldova recorded by Lazarev (2011) for D. c. gorodinskii must be also connected with the new taxon.

Acknowledgements. I am very grateful to Larisa Ladovyrya and Grigoriy Demidov for their generous hospitality and cordiality during my sojourn in Odessa and for providing me with the specimens for study. My wife Galina helped me in my collecting efforts. Alexander Bartenev (Kharkov) and Dmitriy Kuleshov (Tomsk) added several own specimens to the type series that considerably improved the description.
