Comparative diagnosis. Probles smaragdites sp. nov. differs from other Palaearctic species of the subgenus Euporizon Horstmann, 1971 by vertex conspicuously impressed posteriorly and occipital carina dipped medially ( Fig. 5); as well as by smooth mesopleuron ( Fig. 7) and dorsolateral areas of propodeum ( Fig. 8). It is also characterised by long lateral longitudinal carinae of scutellum; slender and smooth first tergite with small isolat- ed glymma; and relatively large clypeus ( Fig. 4).

Description. Female. Body length 4.2 mm, fore wing length 3.35 mm.

Head distinctly constricted and rounded behind eyes in dorsal view; gena 0.55 times as long as eye width ( Fig. 6). Clypeus lenticular, 2.8 times as broad as high, slightly convex, separated from face by weak furrow, smooth, with fine punctures in upper 0.3–0.4 ( Fig. 4). Mandible robust, weakly tapered; upper tooth about as long as lower tooth. Malar space 0.5–0.7 times as long as basal mandibular width. Antennal flagellum slightly tapered towards apex, with 21–22 flagellomeres ( Fig. 1); subbasal flagellomeres 1.3–1.5 times as long as broad ( Fig. 3); flagellomeres four to six with subapical finger-shaped structures on outer surface ( Fig. 3). Face finely punctate on finely granulate or nearly smooth background. Frons finely and densely punctate on granulate background (punctures mostly indistinct because of granulation). Vertex and gena shallowly granulate, dull to weakly shining, with very fine (sometimes indistinct) punctures. Vertex posteriorly impressed; occipital carina complete, mediodorsally dipped ( Fig. 5).

Mesoscutum granulate, dull, with moderately dense fine punctures ( Fig. 5). Notaulus with strong wrinkle on anterolateral side of mesoscutum ( Fig. 5). Scutellum with lateral longitudinal carinae long, extending from its base to posterior end of scutellum (in holotype, joining posteriorly). Epicnemial carina with upper end abruptly curved and reaching anterior margin of mesopleuron ( Fig. 7). Mesopleuron mostly smooth and shining, with very fine and sparse punctures. Foveate groove of mesopleuron deep and long, anteriorly upcurved, with transverse wrinkles ( Fig. 7). Propodeum with basal area somewhat widened anteriorly, about twice as long as anteriorly broad ( Fig. 8) and 0.7 times as long as apical area; dorsolateral area smooth and shining ( Fig. 8); apical area truncated anteriorly, flat, somewhat uneven; apical longitudinal carinae distinct, reaching transverse carina anteriorly. Propodeal spiracle separated from pleural carina by two diameters of spiracle.

Fore wing with second recurrent vein (2 m-cu) distinctly postfurcal. Metacarpus (R 1) reaching apex of wing. First abscissa of radius (Rs+ 2 r) straight, longer than width of pterostigma. Intercubitus (2 rs-m) long, slightly thickened, almost as long as abscissa of cubitus between intercubitus and second recurrent vein (abscissa of M between 2 rs-m and 2 m-cu). Hind wing with subvertical nervellus (cu 1 and cu-a). Legs slender. Tarsal claws very long and thin.

First metasomal tergite slender, about 3.4 times as long as posteriorly broad, entirely smooth; petiole round in cross-section; postpetiole in dorsal view strongly widened, clearly separated from petiole. Glymma small, situated slightly behind middle of first tergite and joining to ventral part of postpetiole by very shallow (evanescent) furrow. Second tergite 1.1 times as long as anteriorly broad. Thyridial depression distinct, as long as broad (paratype) or slightly elongate (holotype). Ovipositor slender, weakly and evenly upcurved, with dorsal subapical depression and rounded tooth before this depression ( Fig. 9); sheath about 1.5 times as long as first tergite.

Body predominantly dark reddish brown, head and mesosoma dorsally blackish ( Fig. 1); clypeus yellowish red, mandible (teeth reddish) and mouthparts yellow. Antenna yellowish brown basally to dark brown apically. Tegula reddish brown. Pterostigma brown. Legs brownish yellow, hind coxa slightly darkened with brown.

Male ( Fig. 2). Flagellum with 21 flagellomeres. Second tergite about twice as long as anteriorly broad. Thyridial depression elongate. Otherwise similar to female.

Etymology. The species name is an adjective derived from the Greek and Latin word smaragdus (emerald), with the addition of the suffix -ites.

Distribution. Russian Far East.
