Virgichneumon albosignatus (GRAVENHORST, 1829) View in CoL (figs 1, 23, 43, 62, 80)

Lectotype: (♁) (Wroclaw), studied and comb. nov. by RASNITSYN (1981).

D e s c r i p t i o n: ♀. Body length 7.5-10.5 mm. Flagellum with 35-39 segments, slightly lanceolate; 1 st flagellar segment 1.5× as long as wide; 5 th segment square; widest segments 1.1-1.3× as wide as long. Temple slightly to moderately and roundly narrowed behind eye (fig. 1). OED 1.6-1.9× and OOD 2.0-2.2× ocellar diameter. Clypeus with sparse punctures. Gena wide, 1.2-1.3× as wide as eye, with very sparse punctures ventrally (fig. 80).

Epicnemial carina low behind fore coxa. Scutellum wider than long, without or with lateral carina in the basal 0.2. Area superomedia heart-shaped, slightly longer than wide or wider than long; usually posterior to its middle with costula (fig. 23). Hind coxa densely punctate, with large scopa. Hind femur densely punctate, 3.1-3.3× as long as wide. External surface of hind tibia with few (2-4) denticular spines. Areolet pentagonal, frontal distance between veins 2rs-m and 3rs-m 2× their width; vein 2m-cu distad its middle. Vein 1cu-a postfurcal.

Postpetiole with distinct latero-median carina; median field elevated, densely punctate and ± rugose. Gastrocoelus almost triangular. Thyridium slightly oblique, 0.4-0.5× as wide as interval between thyridia (fig. 43). 2 nd tergite 1.4× as wide as long. 2 nd and 3 rd tergites densely punctate, strongly shining; 2 nd tergite slightly rugose basally (fig. 43). Ovipositor sheath slightly extending beyond metasomal apex.

Color: black. Setae of mesoscutum brownish. Scopa whitish. Flagellar segments 8-14 dorsally, small spot on frontal orbit opposite of ocelli, scutellum and large dorsal spot of 7 th tergite ivory. Coxae and trochanters black; legs otherwise red; hind tibia infuscate in apical 0.1-0.2; hind tarsus blackish. Pterostigma ochreous.

♁. Body length 9.0-11.0 mm. Flagellum with 35-41 segments, bristle-shaped, distal segments slightly nodose; 1 st flagellar segment 2.3× as long as wide. Tyloids on flagellar segments 5/7-16/18, linear to long-oval, as long as their segments. Temple slightly and roundly narrowed behind eye. OED 1.5-1.7× and OOD 1.6-2.1× ocellar diameter. Clypeus with sparse punctures. MI 0.5. Fore metatarsus without or with weak blunt apical tooth. Hind femur 3.5-4.0× as long as wide. 2 nd tergite 1.1× as wide as long. 2 nd to 4 th tergites with dense coarse punctures and fine granulation.

Color: black. Palps and mandible except teeth reddish, rarely brownish. Side of clypeus usually, wide facial orbit, narrow frontal orbit (fig. 62) and scutellum ivory; sometimes also spot of collar, spot of tegula and median mark of 7 th tergite ivory. Coxae and trochanters black; legs otherwise reddish; hind tibia in apical 0.1-0.2 and hind tarsus completely black. Pterostigma ochreous.

T a x o n o m i c a l r e m a r k s: The ♁♁ are separated in two groups: with ivory scutellum and 7 th tergite, but with black clypeus, frontal orbit, tegula and subtegular ridge OR with black 7 th tergite and sometimes scutellum, but with ivory clypeus and frontal orbit and at least ivory spots on tegula and subtegular ridge.

The systematic position of these groups is unclear yet, and genomic studies should be helpful to solve the taxonomic relation of these groups in the future.
