(Figs 4 B, 5C, 6E, 7B)
Diagnosis. Atractodes reijoi can be distinguished from all other species of the A. propodeator species-group by the combination of the following characters: antenna with 19 flagellomeres, central flagellomeres clearly thicker than the distal ones, the seventh one 1.7–2.1 × as long as broad, width of the penultimate 0.83–0.9 × the width of the seventh one (Fig. 4 B); ventral part of gena and ventral part of mesopleuron with very sparse and relatively short setae (Fig. 5 C); antenna entirely dark brown (Fig. 5 C); metasomal tergites I–II and anterior third of tergite III dark brown to black, rest of tergites, light orange (Fig. 7 B). Body length: 9.0– 12.6 mm.
Description. Female: Body length 9.0– 12.6 mm. Fore wing 7.2–9.0 mm long.
Head. Transverse, about 0.5–0.6 × as wide as long, not narrowed behind compound eyes, rounded (viewed from above); gena about 0.6–0.7 × as long as eye, smooth and shiny with very sparse shallow setiferous punctures, setae relatively short and sparse at ventral part. Frons and vertex mostly smooth and shiny with dense shallow setiferous punctures, frons rugose behind the antennal sockets, setae relatively short. Occipital carina rounded in middle part. Posterior ocellus separated from eye by 1.4–1.7 × its own maximum diameter; distance between posterior ocelli 0.4–0.6 × its own maximum diameter. Face finely and very densely punctate on a granulate background. Clypeus weakly convex, 2.0–2.5 × as wide as long, densely punctate on a smooth and shiny background, apex slightly upturned medially, setae conspicuously longer than in face. Lower tooth of mandible about 0.8 × the length of upper tooth. Eye glabrous. Malar space about 0.8–0.9 × basal mandibular width, strongly granulate. Antenna with 19 flagellomeres; first flagellomere, seventh and penultimate 3.2–4.0, 1.7–2.1 and 1.4–1.7 × as long as wide, respectively; antenna slightly widened in middle, width of penultimate 0.83–0.9 × the width of first flagellomere (Fig. 4 B).
Mesosoma (Fig. 6 E). Pronotum sparsely punctate in the anterior lateral part, longitudinally strigose in the anterior submarginal depression; dorsal posterior corner granulate; epomia strong in the upper part, then very shallow and shortly extended parallel to the anterior margin of pronotum. Mesoscutum fine and densely punctate on a smooth and shiny background; notauli deep, reaching about 0.4–0.5 × the length of mesoscutum; prescutellar groove deep, smooth, with longitudinal striae; scutellum with sparse fine and shallow setiferous punctures, denser at apex, conforming a shallow vertical strigose microsculpure; lateral carina present, reaching 0.7–0.8 × its length. Mesopleuron shiny, with moderatelly strong and sparse setiferous punctures; central part smooth and glabrous, ventral part with very short and relatively sparse setae; sternaulus deep, reaching about 0.75 × the width of mesopleuron, not strigose or rugose. Metapleuron strongly rugose and sparsely setose; juxtacoxal carina absent. Propodeum mostly strongly rugose, shiny, setae long and sparse; median area strongly strigose transversally, conspicuously broader in the central part, about 1.8–1.9 × as long as its maximum width, flat; spiracle small, rounded, separated from pleural carina 2.3–2.9 × its diameter. Legs long and slender; length of hind femur 4.3–4.8 × its width; hind tarsal claws thin and right-angled curved, clearly longer than arolium.
Wings. Densely setose. Fore wing with pterostigma about 3.3–3.7 × wider than high, vein Rs +2 r about 1.9–2.1 × longer than its height; areolet pentagonal, open, about 0.6–0.7 × higher than wide; 2 m-cu with a single bulla; first abscissa of Cu 1a 1.3–1.6 × Cu 1b. Hind wing with vein cu-a + abscissa of Cu 1 between M and cu-a angulate, intercepted at its lower 0.2–0.3, reclivous; distal abscissa of Cu 1 distinctly pigmented.
Metasoma (Figs 5 C, 7B). Tergite I very finely granulate, with few short lateral setae and fine longitudinal wrinkles, 3.0–3.7 × longer than posteriorly broad, in lateral view dorsal part strongly curved; cross section of petiole rectangular, upper side flat; tergite II polished, about 1.9–2.1 × longer than basally broad; lateral crease separating tergite II from epipleurum slightly present at basal third; other tergites smooth and shiny, with only very few sparse setae.
Colouration (Fig. 5 C). Body black; mandible teeth black; antenna entirely dark brown. Legs black to dark brown. Metasoma from posterior half of tergite III to the apex light orange; tergites I–II and anterior third of tergite III dark brown to black.
Male: unknown.
Etymology. This species is named in honour of Dr. Reijo Jussila, in recognition of his outstanding work on the western Palaearctic Stilpnina taxonomy.
