Diagnosis. Miscophus schmideggeri belongs to the M. bytinskii species group, characterized by obtuse angle between propodeal dorsum and propodeal declivity, seen in lateral view, without any edge or keel at the transition (except medially), mesosoma conspicuously narrowed posteriorly (dorsal view), body predominantly smooth and shiny, without or with sparse punctation, propodeal enclosure smooth and markedly shiny, at most whith some barely visible oblique and transverse striae near median carina, pilosity predominantly reduced and barely visible. The group includes seven described species. Miscophus schmideggeri differs from all of them by densely punctate, not polished frons, distinct sparse white pilosity on propodeal enclosure basally, and darkened forewing with relatively small and contrasting clear areas on submarginal I, discoidal I (in apical half) and discoidal II (except apex) cells. It is similar to Miscophus liebigi Schmid-Egger & Ghaderipour, 2025 , from which it differs (in addition to the abovementioned features) by indistinct frontal median furrow (well-defined in M. liebigi ), three forebasitarsal spines in females (two in M. liebigi ), by the shape of S 8 in males—with apical, wide, split median process and short lateral tooth ( Fig. 28 View FIGURES 25–30 ) in M. schmideggeri and with three very long, spinlike teeth in M. liebigi .

Description. Head ( Figs 20, 21 View FIGURES 17–24 , 26, 27 View FIGURES 25–30 ). Frons slightly convex in lateral view and nearly straight in dorsal view, with indistinct median furrow, nearly shagreened (smoother in male), with sparse short white setae below. Vertex and gena shiny, with ill-defined sparse punctuation and short white setae.

Mesosoma. Pronotal collar near posterior margin medially roundly elevated. Mesonotum shiny, with ill-defined sparse punctation. Mesopleuron indistinctly sculptured, posteriorly with few rugae, nearly asetose. Propodeal enclosure with few basally oblique and apically transverse rugae, between oblique rugae with sparse white setae ( Fig. 22 View FIGURES 17–24 ). Propodedal lateral and posterior surfaces finely rugose.

Wings. Fig. 23 View FIGURES 17–24 .

Metasoma. Shiny, with ill-defined sparse punctation.

Coloration. Black with the following ferruginous: clypeal apex, palpi, scape and pedicel below, mandible (except black base and amber apex), foretibia and foretarsus. Tegula, mid- and hindtibiae and tarsi brownish. Some specimens from Kazakhstan with more extensive ferruginous coloration in legs, scape and pedicellus ( Fig. 19 View FIGURES 17–24 ). Forewing darkened with relatively small and contrasting clear areas on submarginal I, discoidal I (in apical half) and discoidal II (except apex) cells ( Fig. 23 View FIGURES 17–24 ).

Female ( Figs 17–24 View FIGURES 17–24 ). Body length 3.9–5.0 mm ( holotype 5.0 mm).

Head ( Figs 20–21 View FIGURES 17–24 ) ratio H:W = 0.90, ratio POL:OOL = 2.24. Ratio of clypeal median lobe width to clypeus width = 0.53.

Legs. Forebasitarsus with three black spines, apical spine as long as second tarsal article ( Fig. 24 View FIGURES 17–24 ).

Male ( Figs 25–30 View FIGURES 25–30 ). Body length 3.6–4.2 mm.

Head (26, 27) ratio H:W = 0.85, ratio POL:OOL = 1.51. Clypeal median lobe convex, arcuate apically and with nearly straight lateral sides.

Legs. Forebasitarsus with two black spines, apical spine near half of second tarsal article length.

Metasoma. S 8 ( Fig. 28 View FIGURES 25–30 ) with wide, apically split median process and short lateral tooth.

Genitalia. Paramera— Fig. 29 View FIGURES 25–30 ; penial valvula— Fig. 30 View FIGURES 25–30 .

Etymology. The species is named in honour of the German hymenopterologist Christian Schmid-Egger, who described most species of this group.

Distribution. Russia ( Kalmykia and Dagestan republics, Astrakhan Province), Kazakhstan.
