Abstract: Xylotrechus arvicola arvicola (Olivier, 1795) from different localities of West Europe (France, Italy, Germany, Czechia, Bulgaria) is illustrated. X. a. iranicus Rapuzzi & Sama, 2014, stat. nov. (originally described as a species) is recorded for Azerbaijan (Lenkoran distr.) and illustrated. X. a. planarius ssp. n. is described from Central and South of European Russia and from Ukraine. X. a. lazarevi ssp. n. is described from Russian Caucasus and Transcaucasia: Georgia, Armenia, Azerbaijan (without Talysh area).
Xylotrechus (s. str.) arvicola (Olivier, 1795) was described "du midi de la France". The species has a very large area (from Iberian Peninsula to European Russia, Transcaucasia, Kazakhstan, Turkey, Syria and North Africa) and demonstrates considerable geographical variability.
The nominative subspecies is known to me on the base of several specimens from France (2 males, 2 females: Orange, Saorge, Fontenbleau - ZIN, MD: Figs 1-2), Italy (2 males, 2 females - MD -Figs 3-4), Czechia (1 female, Breclav, VI.1981, J.Hala - ZIN: Fig. 6), Germany (1 male - ZIN - Fig. 5). It is characterized by wide elytral yellow lines and usually yellow elytral bases; curved elytral band is rounded posteriorly. Specimens from near Berlin (3 males, 7 females - ZIN) can not be attributed to X. a. arvicola because of narrow yellow elytral design and very narrow yellow stripe across elytral bases. Probably that population could be joined to Russian subspecies described bellow as new. Similar form are known from Austria (1 male, "Austria, Miller" - ZIN), but another available specimen (1 female, "Styria, Kor Alpe, R. Schreitter, Graz" - ZIN) represents the nominative subspecies. Populations in Bulgaria looks similar to the nominative subspecies (Fig. 7, male, "Lompalanka" -
ZIN), as well as a female (ZMM) with a single label "Balkanen".
Xylotrechus arvícola iranicus Rapuzzi & Sama, 2014, stat. nov. was described as a species from North Iran (Mazandaran and Golestan) on the base of 2 males and 4 females. All characters listed by the authors in order to distinguish their new taxon from X. arvícola are about same as in the populations of X. arvícola from Central Russia (so its separate species status can not be accepted): thinner elytral bands (bands of specimens from Russia are often much thinner, than in specimens from Iran); curved elytral band is angulated instead of rounded (curved elytral band in Russian and Caucasian specimens are often much more angulated than in specimens from Iran); humeral spot is oblique instead of horizontal (humeral spots in Russian and Caucasian specimens are often as oblique as in specimens from Iran); shoulders are black, instead of being brown covered by yellow pubescence in X. arvicola (shoulders in X. arvícola from Russia and Transcaucasia are more often black than brown); the sculpture of the middle of pronotum is not so strong as in X. arvícola (the character is strongly variable and many forms of different pronotal sculpture are known); elytra are narrower towards the apex than in X. arvícola (this character is also rather variable).
Specimens of Xylotrechus arvícola from South East Azerbaijan (Figs 8-9) - 4 males, 8 females, Talysh area, Avrora environs, 38°39'18"N, 48°48'08"E, 15m, 1972, 1979, M. Danilevsky leg. [MD, ML]; 1 female from about same locality, 15.7.1930, T.Safarov leg. [ZMM]; 3 males (9-15 mm), 1 female (14 mm) from Lenkoran environs [ZIN] - are usually just same as specimens described from Iran and must be also attributed to X. a. íranícus Rapuzzi & Sama, 2014, stat. nov. It is separated from similar Russian populations by Caucasian subspecies with wide elytral bands. Both subspecies are described below as new.

Type locality: Russia, Bashkiria, Ay river, Mesyagutovo (about 210M, 55°32'N, 58°15'E).
The subspecies is characterized by very thin yellow elytral lines, usually thinner than in specimens of X. a. iranicus Rapuzzi & Sama, 2014, stat. nov. and much thinner than in the nominative subspecies from Western Europe; prothorax usually strongly transverse in males and in females; pronotal sculpture consists of smaller or bigger transverse granules, which can be rounded; elytral bases usually totally black (pale in the nominative subspecies) or with small pale spots near scutellum (as in the holotype of X. a. iranicus); transverse short line behind humeri can be a little oblique, central elytral line usually rounded or from a little to strongly angulated; male elytra from 2.2 to 2.4 times longer than wide; female elytra from 2.2 to 2.6 times longer than wide; body length in available males: 9.3-14.0, body width: 2.8-3.9mm; body length in available females: 9.7-17.3mm, body width: 3.0-5.0mm.

Distribution. Central and partly south of European Russia with Samara, Saratov, Voronezh, Volgograd and Astrakhan regions; the taxon is definitely known from Bashkiria and Udmurtia; I preliminary attribute to X. a. planarius ssp. n. a single male known from Crimea; the taxon was recorded from many localities of Orenburg Region (Shapovalov, 2012), penetrates to West Siberia (Dubrovnoe in Tyumen Region, about 55m, 57°11'N, 66°35'E) and to northern Kazakhstan; one specimen was collected in the south of Moscow Region (Egoryevsk Distr., Alferovo 24.8.2008, V.Vasilenko leg.); the records from Rostov Region (Arzanov et al., 1993) also could be connected with the new taxon as well as all records from eastern Ukraine from Chernigov to Kharkov, Lugansk and Donetsk (Martynov, Pisarenko, 2004; Bartenev, 2009). The taxonomy position of populations from western Ukraine, Moldavia and from the east of Western Europe is not identified because of no materials available.
The situation at the south of Volga River is not clear. Specimens [ZIN] from near Volgograd and Astrakhan have extremely thin elytral lines (Fig. 18) and so, belong to normal X. a. planarius ssp. n., but a very old male from "Akhtuba" [ZMM: Fig. 33] must be attributed to the next subspecies.
Dagestan population is preliminary attributed here to X. a. planarius ssp. n. because a single available male (13 mm, "Madschalis, Dagestan Geb., Becker" - ZIN: Fig. 19) has very
narrow elytral lines, and so rather similar to Astrakhan population.

Materials. Holotype, male, Krasnodar Region, Ubinskoe (about 150m, 44°44'N, 38°32'E), 6.7.1970, M.Danilevsky leg. - MD; 49 paratypes; 1 male and 3 females, same locality, 1-13.7.1970, M.Danilevsky & B.Mamaev leg. - MD and ML; 2 males and 2 females, Krasnodar, 14.7.1910 ("Ekaterinodar"), 24.6.1969, 15.6.1975, 2.7.1976 - ZMM; 1 female, Ekaterinodar (Krasnodar) Region, Khosta, 5-10.6.1902, A.Silantyev - ZMM; 1 male, Pyatigorsk, 17.7.1905 - ZMM; 1 male, "Cauc. occ., Gagry, 2.VI." -ZMM; 1 male, "Transcauc., prov.

2 males, 1 female, Georgia, Manglisi, 1880-1881 - ZIN; 1 male, Madschalis, Dagestan Geb., Becker - ZIN; 1 female, Kuba Distr., Baku Region (Azerbaijan), VI.97 [1897], Satunin - ZIN; 1 female,

Most probably new subspecies penetrates to northern Turkey; specimens from Syria (ZIN) are similar to X. a. lazarevi ssp. n., but could represent another subspecies. Probably the most northern specimen with largely pale elytral bases and wide yellow elytral lines is labeled as "Gouv. Saratov, Fl. Akhtuba, 30.VI.929, A.Menstschikow" (Fig. 33).
Dedication. The new taxon is dedicated to my colleague Maxim Lazarev (Moscow), who took an active part in the study of available materials.
