A relatively small species ( Figures 4 View FIGURES 1–11 , 15 View FIGURES 12–23 ). Elytra with dense and smooth granulation concentrated at the basal part of elytra only. Elytral apex with dense pubescence. The apical third of elytra is shining due to no micro-reticulation. Pronotum and elytra covered with large yellowish and white spots often forming a transversal band medially on elytra ( Figures 4 View FIGURES 1–11 , 15 View FIGURES 12–23 ). Scutellum with a narrow and glabrous, transversal median line (visible in well preserved specimens). Pronotum has elongated, transversal ridges. The lateral spines on pronotum are short and blunt. Head (front view) elongated. Antennae long: longer than body with five to six antennomeres in males, and with three to four antennomeres females. Type locality: Russia, Siberia (Altai, Kolywan ) .

Examined males: length 11.9–18.4mm, width 4.0– 5.5mm; female: length 16.4mm, width 5.5mm.

Male terminalia. Aedeagus: 2.0– 2.1mm long, relatively slender, evenly curved towards apex, dorsal ridge as wide as ventral ridge, dorsal and ventral ridges rounded at apex ( Figures 59, 60 View FIGURES 51–62 ). Colour dark brown to black. Endophallus: approx. 5.0mm long and evenly broad from

median to apical phallomer ( Figure 33D View FIGURES 33–35 ). The two yellow crescent-shaped sclerites at the proximal end of the basal phallomer very fine, twisted and completely folded ( Figure 47 View FIGURES 45–50 ). Lower part of median phallomer with two rounded micro-reticulated patches on the phallomer membrane ( Figure 33D View FIGURES 33–35 ). Internal sac (apical part of median phallomer): No sclerites inside internal sac. The surrounding intersegmental membrane with very fine micro-reticulation ( Figure 38 View FIGURES 36–44 ). Tegmen: 2.1– 2.5mm long, base of tegmen extended and weakly curved dorso-ventrally on middle. Parameres: elongated, slender and flattened dorso-ventrally, weakly separated medially along inner margin and connecting towards apex ( Figures 75, 76 View FIGURES 73–78 ). Base of inner margin with an extension from each paramere projecting forward forming a small “tooth” ( Figure 75 View FIGURES 73–78 ). Apex evenly rounded along posterior margin with scattered fringes of short, brownish hairs well concentrated at edge of apex ( Figure 75 View FIGURES 73–78 ). No micro-reticulation on parameres. Base of tegmen, at lower part of median lobe, extended and strongly curved dorso-ventrally on middle. Tergite VIII: 1.0– 1.2mm long, with brownish pigmentation, posterior margin slightly elongated ( Figure 85 View FIGURES 79–87 ) or evenly rounded ( Figure 86 View FIGURES 79–87 ) and covered with short, very fine brownish hairs distally towards the posterior margin. Surface with very weak micro-reticulation medially.

Female terminalia. Tignum: almost straight, 7.2mm long (width: approx. 0.15mm at the widest point apically; Figure 31 View FIGURES 26–32 ). Tergite VIII: posterior margin (width: approx. 1.5mm) with sparse and relatively long fringes of dark brown hairs laterally ( Figure 31 View FIGURES 26–32 ), surface dorso-laterally with numerous small granulae, covered with dense and fine yellowish pubescence (the individual hairs twice as long as in any other European species of Monochamus ) and a few brownish setae, dorso-medially mostly with very weak micro-reticulation (with a more or less shining area medially), and a very weak longitudinal impression. The colour is white to yellowish and brown apically. Spermathecal capsule: Weakly sclerotized, whitish to yellowish, relatively long, widened at base, and curved almost 180° towards apex ( Figure 31 View FIGURES 26–32 ). Apex with an elongated head, 1.2mm long.
