Flagellum with 29 segments, moderately lanceolate; 1 st flagellar segment 2.0× as long as wide, 8 th or 9 th segment square; widest segments 1.5× as wide as long, preapical segment wider than long, tip blunt (fig. 79). Temple moderately and roundly narrowed behind eye (fig. 7). OED 1.1- 1.2× and OOD 1.3× ocellar diameter. Frons with fine superficial punctures, granulate. Gena about as wide as eye, with sparse punctures ventrally. MI 1.0-1.1.

Epicnemial carina low behind fore coxa. Scutellum slightly wider than long, rather coarsely punctate, without lateral carina. Area superomedia heart-shaped, about as long as wide; at its middle with costula (fig. 29). Hind coxa without scopa, densely punctate. Hind femur 3.6× as long as wide. External surface of hind tibia without or with few (1-2) denticular spines. Areolet pentagonal, frontal distance between veins 2rs-m and 3rs-m 2× their width; vein 2m-cu reaching distad its middle. Vein 1cu-a postfurcal by 1× its width.

Postpetiole with latero-median carina; median field elevated, punctate and ± aciculate. Gastrocoelus rectangular. Thyridium 0.6-0.7× as wide as interval between thyridia. 2 nd and 3 rd tergites densely punctate; 2 nd tergite distinctly aciculate basally (fig. 49). Ovipositor sheath extending beyond metasomal apex by length of 7 th tergite.

Color: black. Setae of mesoscutum grey. Flagellar segments 7-12 dorsally, spot on frontal orbit opposite to lateral ocellus, and 6 th and 7 th tergites almost completely ivory. Coxae and trochanters black; legs otherwise red, sometimes hind femur and usually hind tibia ± infuscate apically, hind tarsus blackish. Pterostigma ochreous.

♁. Body length 9.0- 10.5 mm. Flagellum with 32-34 segments; 1 st flagellar segment 2.7× as long as wide. Tyloids on flagellar segments 5-13/15, long-oval, black, maximally 0.8× as long as their segments. OED 1.1-1.2× and OOD 1.2× ocellar diameter. Fore metatarsus without apical tooth. Scutellum with lateral carina in basal 0.3. Hind femur 3.4-3.5× as long as wide. Median field of postpetiole often ± striate. Posterior margin of hypopygium with a triangular and pointed median extension.

Color: black. Flagellum reddish ventrally. Palps, mandible, clypeus and face (fig. 67), scape ventrally, frontal and outer orbits, collar and upper margin of pronotum, spot on tegula, subtegular ridge, two postero-lateral spots on scutellum (sometimes confluent), sometimes small posterolateral spots on postpetiole and 2 nd tergite, wide spots on 6 th and 7 th tergites, spot on paramere, and hind margins of apical sternites ivory. Coxae and trochanters black; legs otherwise red; hind femur and hind tibia apically (or mainly) and hind tarsus entirely infuscate. Pterostigma pale brownish.

Taxonomical remark: The ♀ differs from V. krapinensis by wider preapical flagellar segments, blunt flagellar tip, and reduced denticular spines on hind tibia.
