*Couplets 1 to 4 work for both sexes, couplets 5 to 7 work only for females.

1. Foveate groove of mesopleuron narrow and sharp, usually about half as long as mesopleuron length (Fig. 7). Frons finely punctate on more or less smooth background. Lower 0.7–0.8 of clypeus flat, separated by transverse crease from upper 0.2–0.3 of clypeus. Apex of ovipositor lanceolate, equally tapered dorsally and ventrally, with very small and narrow dorsal subapical notch (Fig. 15)........................................................................................ 2

- Foveate groove weak and shallow (Fig. 8), usually as somewhat more densely granulate area, sometimes with very fine wrinkles. Frons granulate, impunctate. Clypeus sometimes flat. Apex of ovipositor not as above, with wide dorsal depression or teeth, or with notch but then not lanceolate, straight dorsally and stepped ventrally (Fig. 16).......................... 3

2. Ovipositor sheath 3.8–4.6 times as long as first tergite. Basal area of propodeum narrow, basal longitudinal carinae more or less parallel (Fig. 9). Scape and pedicel of antenna ventrally yellowish, distinctly paler than flagellum (Fig. 3). Flagellum of female with 17–18 flagellomeres................................................................ G. cuspidatus

- Ovipositor sheath 2.2–2.5 times as long as first tergite. Basal area of propodeum widened anteriorly (Fig. 10). Antenna more or less uniformly dark brown or black (Fig. 4) Flagellum of female with 16–17 flagellomeres........... G. provectus sp. nov.

3. Temple densely granulate (Fig. 5), dull, without or with very indistinct punctures. Large species with body length 4.8–6.4 mm and fore wing length 4.5–5.1 mm ............................................................. G. belokobylskii

- Temple smooth and shining (Fig. 6). Small species with body length not exceeding 3.5 mm and fore wing shorter than 3.0 mm.....................................................................................................4

4. Propodeum with short basal keel (Fig. 11) or rarely with very narrow basal area. Ovipositor robust, with apex rather thick, with wide dorsal subapical depression and usually with two more or less distinct teeth before and behind this depression (Fig. 16)...................................................................................... G. protritus sp. nov.

- Propodeum with basal area (Fig. 12). Ovipositor usually slender at apex. (Females.)................................. 5

5. Ovipositor with deep and narrow dorsal subapical notch, apex more or less straight dorsally and stepped ventrally (Fig. 17). Basal area wide, about 1.5 times as long as broad (Fig. 12). First tergite with petiole dorsally smooth. Ovipositor sheath 2.0– 2.5 times as long as first tergite................................................................. G. simillimus

- Ovipositor with wide dorsal subapical depression (Fig. 18). Other characters varied................................. 6

6. Upper tooth of mandible as long as lower tooth. Flagellum distinctly clavate, subapical flagellomere square to slightly transverse (Fig. 1). Ovipositor very slender, usually straight in basal 0.9, with apex conspicuously stronger upcurved, with shallow dorsal depression and very small notch before this depression (Fig. 19)............................ G. verendus sp. nov.

- Upper tooth of mandible longer than lower tooth. Flagellum filiform or slightly clavate, subapical flagellomere usually elongate (Fig. 2). Ovipositor moderately slender to robust, evenly upcurved and with dorsal depression stronger (Fig. 20)...... 7

7. First metasomal segment with petiole distinctly striate dorsally (Fig. 13). Ovipositor slender, with dorsal subapical depression far from apex, distance from depression to apex of ovipositor subequal to 4.0 times average height of ovipositor (Fig. 20). Antenna brown............................................................................. G. gubarevae

- First metasomal segment with petiole smooth dorsally (Fig. 14). Ovipositor less slender, distinctly widened apically, with dorsal subapical depression closer to apex (Fig. 18). Scape and pedicel of antenna yellowish, flagellum brown................................................................................................... G. dentator sp. nov.
