A medium-sized species ( Figures 1 View FIGURES 1–11 , 12 View FIGURES 12–23 ). Basal half of elytra have rough granulation and distinct punctuation, especially towards humeri. Scutellum often with a glabrous, transversal median line reaching from base to apex (visible in well preserved specimens). Elytra covered with a few to numerous yellowish spots, irregularly distributed on the elytra ( Figures 1 View FIGURES 1–11 , 12 View FIGURES 12–23 ). Elytra in the subspecies M. sutor longulus is slightly more elongated and surface glabrous (shining). Lateral part of pronotum with numerous fine hairs ( Figure 24 View FIGURES 24–25 ), both below and above the lateral spine (visible in well preserved specimens). Antennae long, longer than body with five to six antennomeres in males, and with three to four antennomeres in females. Type locality: “Europe” (country not specified).

Examined males: length 16.0–23.0mm, width 5.5–7.0mm; females: length 19.8–23.0mm, width 4.5–7.0mm.

Male terminalia. Aedeagus: 2.3–2.9mm long, relatively stout, and evenly curved towards apex, dorsal ridge as wide as ventral ridge and both ridges rounded at apex ( Figures 51, 52 View FIGURES 51–62 ). Colour dark brown to black. Endophallus: approx. 7.0mm long, and narrowed from median to apical phallomer ( Figure 33A View FIGURES 33–35 ). The two brownish and crescent-shaped sclerites at the proximal end of the basal phallomer relatively narrow, and completely folded ( Figure 45 View FIGURES 45–50 ). Internal sac (apical part of median phallomer): the major part consists of a weakly sclerotized structure (approx. 0.5mm long) inside the internal sac ( Figures 33A, 35 View FIGURES 33–35 , 36 View FIGURES 36–44 ), forming a small “beak-like” structure acutely narrowing anteriorally. Internal sac has surrounding intersegmental membrane with distinct and coarse micro-reticulation. Tegmen: 2.9–3.0mm long, base of tegmen extended and curved dorso-ventrally on middle. Parameres: elongated, slender and flattened dorso-ventrally, well separated medially along inner margin and often connecting towards apex ( Figures 63, 64 View FIGURES 63–72 ). Base of inner margin has a distinct extension from each paramere projecting forward forming a “tooth” ( Figure 63 View FIGURES 63–72 ). Apex evenly rounded along posterior margin with scattered fringes of relatively short, brownish hairs well concentrated at edge of apex. Ventral surface of parameres with scattered punctures and fine hairs concentrated at apex. No micro-reticulation on parameres. Tergite VIII: 1.5–1.8mm long, with brownish pigmentation, posterior margin elongated and narrowly rounded, and covered with short, fine brownish hairs distally towards the posterior margin ( Figure 79 View FIGURES 79–87 ). Surface has very weak micro-reticulation medially.

There is no difference in the male genitalia characters between the examined specimen of M. sutor longulus and M. sutor sutor .

Female terminalia. Tignum: long, straight shaft which is almost as long as abdomen ( Figure 26 View FIGURES 26–32 ), mostly straight but sometimes slightly twisted apically, 8.1–9.5mm long, width approx. 0.2mm at the widest point apically. Tergite VIII: width of posterior margin approx. 2.0mm, with sparse and relatively long fringes of dark brown hairs laterally ( Figure 26 View FIGURES 26–32 ), surface dorso-laterally with numerous small granulae, and covered with relatively dense and very fine yellowish pubescence and a few brownish setae, and dorso-medially with more or less weak micro-reticulation and a weak longitudinal impression. The colour is brown. Spermathecal capsule: weakly sclerotized, whitish to yellowish, relatively long, widened at base, and weakly curved about 90° towards apex ( Figure 26 View FIGURES 26–32 ). Apex with an elongated head, 1.2mm long.
