Aphidius hedini Fahringer, 1929: 2 ; Shenefelt 1969: 116 (examined: lectotype here designated, ♂ (NHRS) “[ Russia:] Kamschatka, [R.] Malaise”, “146”, “Type”, “ Aphidius Hedini m. [in Fahringer’s handwriting], “121 58”, “ Myiocephalus boops Wesmael , ♂, = Aphidius hedini Fahr. , n. syn., det. P. Starý, 1958”, “NHRS-HEVA 00000 7454”. Three additional ♂ speci- mens (7455–57) are paralectotypes.

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.
