Material. 1 ♀ (RMNH), “[Austria:], Carinthia, Afritzer See, 740–840 m, 3–10.vii.1964, G. van Rossem ” ; 1 ♂ (RMNH), “ Nederland: [DR], Boschoord-Vledder, nr. Steenwijk, 27.vii.1982, P. Koomen ” .

Short diagnosis. Length of malar space of ♀ 1.2 × basal width of mandible (Fig. 11); area near occipital carina and occiput dorsally pale yellow (Fig. 10); width of face of ♀ 0.9 × combined height of face and clypeus (Fig. 9; measured from ventral rim of antennal socket to ventral border of clypeus); length of malar space of ♀ 1.2 × basal width of mandible (Fig. 11); malar space of ♀ in anterior view nearly straight (Fig. 9); mesopleuron of ♀ anterodorsally largely finely coriaceous and without rugae medially (Fig. 4); mesosoma laterally and legs largely brownish yellow (Figs 1, 4); basal half of first metasomal tergite with laterope visible in dorsal view (Fig. 6); hypopygium of ♀ largely sclerotized, keeled ventrally, subtruncate or rounded posteriorly and with long setae (Fig. 8); ovipositor (except basally) slender (Fig. 2).

Distribution. West Palaearctic: * Austria, Belgium, Bulgaria, Czech Republic, Finland, France, Georgia, Germany, Hungary, Iran, Ireland, Lithuania, * Netherlands, Norway, Poland, Switzerland. East Palaearctic: China (Heilongjiang, Taiwan), Korea, Mongolia, Far East Russia (Yu et al. 2016).

Notes. The North American specimens identified as M. boops (Wesmael) actually belong to a separate but very similar species (= M. laticeps (Provancher, 1886) re-instated), because the shape of the head is different (Fig. 56 and Fig. 62 in Shaw 1997), the malar space is concave in anterior view, the male scapus is distinctly compressed and length of the malar space of ♂ 1.3 × basal width of the mandible.
