Type material. Holotype: female, Russia, Primorskiy Territory, Vladivostok, Sanatornaya Station , forest, 26.VII.1984 (S. Belokobylskij leg.) ( ZISP).

Description. Female. Head smooth, shining, with sparse setae, subcubical (dorsal view), wider than mesosoma at level of tegula. Eye large, widely oval, below convergent to clypeus (front view), bare. Temple 1.3 × larger than eye length (dorsal view). POL equal to Od. Face and clypeus with sparse setae. Clypeus about 0.5 × as high as wide. Tentorial index 0.37.

Antenna filiform, with 13 antennomeres, with semi-erect setae, length of seta shorter than width of antennomeres. F1 5.0 × longer than maximum width, F2 3.5 × longer than width, 0.7 × as long as F1.

Mesosoma. Mesoscutum smooth, shining, almost glabrous. Notauli well developed, long, fused each other before posterior margin of mesoscutum. Propodeum with pair of divergent carinae in its posterior part, which are laterally not bifurcated and reaching spiracles.

Wings. Pterostigma widely triangular, its basal part (before radial (r) vein) 1.3 × longer than apical part; pterostigma 3.2 × longer than maximum width, 2.6 × longer than metacarpus (1-R1) and 1.1 × longer than radial vein (r+3SR+SR1). First abscissa of medial vein (1-SR+M) 0.6 × as long as second abscissa (2-M). Radial (r+3SR+SR1), first (1-SR+M) and second (2-M) abscissae of medial veins almost completely desclerotised and discolored. Recurrent vein (m-cu) absent. Cubital (M+CU), longitudinal anal (1-1A) and parallel (CU1a) veins discolored. Hind wing with weakly perceivable medial (basal) cell.

Metasoma. Petiole 1.25 × longer than its width at level of spiracles, with two longitudinal and almost parallel carinae finishing in posterior part of petiole nearly discal bulges with setae in center. Anterior margin of second tergite dorsally without transverse prominent area. Hypopygium with hardly visible transverse striation (lateral view). Ovipositor sheath 3.0 × longer than its maximum width, distinctly narrowed to apex and weakly upcurved, with few short setae and without thickened posterior bristles on its rounded top.

Colour. Body bicolor, dirty yellowish brown. Head (except dark ocelli), scape, pedicel, F1, mouth parts, prothorax, meso- and metapleura, fore and middle legs yellow. Flagellomeres from F2, mesoscutum and scutellum brown. Hind legs, propodeum, all metasoma with petiole and ovipositor sheath brown.

Length of body, antenna and fore wing 1.6, 1.1 and 1.3 mm, respectively.

Male. Unknown.

Hosts. Unknown.

Etymology. Named after the type locality of the new species, Vladivostok City.

Comparative diagnosis. New species is the most similar to A. thailandicum and differs from latter by 13 antennomeres (12 antennomeres in A. thailandicum ), the absence of transverse vein divided submedial (basal) cell on two cells and transverse anal vein (a) (both these veins present in A. thailandicum ), as well as absence of transverse prominent anterior area on second metasomal tergite (this area distinct in A. thailandicum ). The differences between А. vladivostoki sp. nov. and А. tricolor sp. nov. are showed behind description of the latter species.
