A medium-sized species ( Figures 2, 3 View FIGURES 1–11 , 13, 14 View FIGURES 12–23 ). Basal half of elytra has smooth granulation and fine punctuation, especially towards humeri. Scutellum often with a short glabrous, transversal median line only reaching the middle of scutellum

(visible in well preserved specimens). Elytra have a few to numerous yellowish spots often forming a transversal, yellowish or whitish band on the middle of elytra ( Figures 2, 3 View FIGURES 1–11 , 13, 14 View FIGURES 12–23 ). Lateral part of pronotum with just a few setae ( Figure 25 View FIGURES 24–25 ) below the lateral spine (visible in well preserved specimens). Antennae longer than body, with five to six antennomeres in males, and with three to four antennomeres in females. Type locality: France (“Gallia”) .

Examined males: length 11.5–24.5mm, width 5.0–7.0mm; females: length 16.0–22.0mm, width 5.0–7.0mm.

Male terminalia. Aedeagus: 2.3–2.9mm long, relatively stout, evenly curved towards apex, but with base curved backwards, dorsal ridge as wide as ventral ridge, dorsal and ventral ridges rounded at apex ( Figures 53, 54 View FIGURES 51–62 ). Colour brown. Endophallus: approx. 6.5mm long and evenly wide from median to apical phallomer ( Figure 33B View FIGURES 33–35 ). The two brownish crescent-shaped sclerites at the proximal end of the basal phallomer are relatively broad, long, and completely folded ( Figure 46 View FIGURES 45–50 ). Internal sac (apical part of median phallomer): the single sclerite embedded inside a fine membrane in the internal sac ( Figure 37 View FIGURES 36–44 ) consists of a straight shaft (approx. 1.0mm long) anteriorly forming a small “hook” ( Figure 35 View FIGURES 33–35 ). Internal sac and surrounding intersegmental membrane have weak 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 towards apex ( Figures 65, 66 View FIGURES 63–72 ). Base of inner margin has no trace of an extension or “tooth”. Apex evenly rounded along posterior margin with scattered fringes of relatively short, brownish hairs well concentrated at edge of apex. Ventral surface of parameres have dense punctures and fine hairs on the entire surface. Parameres have no micro-reticulation. Tergite VIII: 1.5–1.8mm long, with brownish pigmentation, posterior margin elongated and narrowly rounded, and covered with short, fine light brown and white hairs distally towards the posterior margin ( Figure 80 View FIGURES 79–87 ). Surface has relatively weak micro-reticulation medially.

Female terminalia. Tignum: mostly twisted on the middle ( Figures 27, 28 View FIGURES 26–32 ), 10.5–11.8mm long, width: approx. 0.3mm at the widest point apically. Tergite VIII: posterior margin (width: approx. 2.0mm) with dense and relatively long fringes of dark brown hairs laterally ( Figures 27, 28 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 mostly with more or less weak micro-reticulation (with a more or less shining area medially), and a weak longitudinal impression. The colour is brown. Spermathecal capsule: Weakly sclerotized, whitish to yellowish, relatively long, widened at base, and curved almost 180° towards apex ( Figures 27, 28 View FIGURES 26–32 ). Apex with an elongated head, 1.4mm long.

Remarks. No difference in the male or female genitalia characters was found between specimens of the former subspecies M. galloprovincialis pistor and M. galloprovincialis galloprovincialis . The former subspecies M. galloprovincialis pistor is the form that occurs in the Scandinavian countries. ( Ehnström &Axelsson 2002, Heliövaara et al. 2004, Ehnström & Holmer 2007).
