A large and robust species ( Figures 6, 7, 8 View FIGURES 1–11 , 17, 18 View FIGURES 12–23 ). A distinct elevated area on the middle of basal third of elytra is followed by an impression immediately below the elevation. Basal half of elytra have dense granulation formed by smooth and raised granulae, especially towards humeri. Elytra have fine, sparse punctuation, often surrounded by short, slightly raised longitudinal and transversal carinae forming a fine square-formed pattern towards apices. Apical third has mostly weak, brownish pubescence (sometimes coarser near apices). Exposed integument on elytra shining, sometimes with a slight metallic lustre. Elytra in males sometimes with scattered yellowish spots or maculae ( Figure 18 View FIGURES 12–23 ). Elytra in females with four conspicuous to distinct whitish to yellowish spots: two above and two

below the middle, and sometimes with small scattered yellowish spots on the elytra ( Figures 6, 7, 8 View FIGURES 1–11 ). Pronotum in males mostly black ( Figures 17 View FIGURES 12–23 ), and rarely with very small yellowish spots ( Figure 18 View FIGURES 12–23 ). Pronotum in females often with two brownish spots above middle and with brownish pubescence laterally ( Figure 6, 7, 8 View FIGURES 1–11 ). Scutellum completely covered with very dense whitish to yellowish pubescence ( Figure 6 View FIGURES 1–11 ). Type locality: Germany (Dresden) .

Examined males: length 25.5–34.0mm, width 7.0–10.0mm; female: length 24.0– 28.4mm, width 7.0–9.0mm.

Male terminalia. Aedeagus: 3.8–4.1mm long, stout, weakly curved towards apex, dorsal ridge as wide as ventral ridge, dorsal and ventral ridges almost straight at apex ( Figures 55, 56 View FIGURES 51–62 ). Colour yellowish to brown. The aedeagus shows very little variability between specimens from different populations. Endophallus: approx. 9.0mm long and evenly broad from median to apical phallomer ( Figure 33C View FIGURES 33–35 ). The two brownish crescent-shaped sclerites at the proximal end of the basal phallomer broad (broader than in any other European species of Monochamus ), and only partly folded ( Figure 48 View FIGURES 45–50 ). The colour is dark brown in mature specimens. Lower part of median phallomer with an elongated micro-reticulated patch on the phallomer membrane ( Figures 33C View FIGURES 33–35 , 43 View FIGURES 36–44 ). Internal sac (apical part of median phallomer): there is a solid (but not sclerotized) tube, or terminal segment, embedded inside the internal sac ( Figures 33C View FIGURES 33–35 , 39 View FIGURES 36–44 ). The very small sclerotized structure is found inside the apical part of the terminal segment. The small sclerites (approx. 0.1mm long) are “U”-shaped, and show some variability between examined specimens ( Figure 34 View FIGURES 33–35 ). Surface of the internal sac (phallomer membrane) with very fine micro-reticulation ( Figure 40 View FIGURES 36–44 ). Colour yellowish to dark brown. Tegmen: 3.8–4.8mm long, base of tegmen extended and acutely curved dorso-ventrally on middle. Parameres: elongated, slender and flattened dorso-ventrally, well separated medially along inner margin and often connecting towards apex ( Figure 67 View FIGURES 63–72 ). Base of inner margin with a distinct extension from each paramere projecting forward forming a “tooth” ( Figures 67, 69 View FIGURES 63–72 ). Apex evenly rounded along posterior margin with fringes of relatively long, brownish hairs well concentrated at edge of apex (often extended to the apical part of ventral surface) ( Figure 67 View FIGURES 63–72 ). Ventral surface of parameres with scattered punctures and fine hairs ( Figure 68 View FIGURES 63–72 ). No micro-reticulation on parameres. The shape of the parameres show some variability between examined specimens ( Figures 67, 69, 70 View FIGURES 63–72 ). Tergite VIII: 1.8–2.1mm long, with brownish to black pigmentation, posterior margin slightly elongated and narrowly rounded, and covered with short, brownish hairs (mixed with scattered yellowish setae) distally towards the posterior margin ( Figures 81, 82 View FIGURES 79–87 ). Surface with very weak micro-reticulation medially. Some variation (similar to M. saltuarius ) was noted regarding the shape of the posterior margin of tergite VIII ( Figures 81, 82 View FIGURES 79–87 ).

Female terminalia. Tignum: relatively thick (width: approx. 0.5mm at the widest point apically) and almost straight or only slightly curved, 13.9– 14.6mm long ( Figure 29 View FIGURES 26–32 ). Tergite VIII: posterior margin (width: 2.5mm) with relatively long fringes of dark brown hairs laterally ( Figure 29 View FIGURES 26–32 ), surface dorso-laterally with a few scattered and small granulae, covered with very fine yellowish pubescence and a few brownish setae, and dorso-medially with more or less weak micro-reticulation and a distinct longitudinal impression. The colour is brown. Spermathecal capsule: Well sclerotized, yellowish to brownish, relatively long, widened at base, and curved almost 180° towards apex ( Figure 29 View FIGURES 26–32 ). Apex with an elongated head, 1.5mm long.
