Body length (dry-mounted specimens) 920–1250 µm. Head and mesosoma dark brown, petiole light brown, gaster brown; scape and pedicel light brown, flagellum brown (basal funicle segments and usually F1–F3) to dark brown (apical funicle segments and clava); legs light brown. Head with inconspicuous sculpture on face and with reticulate sculpture on vertex. Antenna (Fig. 65) with scape plus radicle either a little longer than or about as long as clava, radicle 0.18– 0.22x length of scape, remainder of scape 4.4–5.1x as long as wide, faintly longitudinally striate; pedicel at least slightly longer than F1; in lateral view, F7 and F8 wider than the remaining funicle segments; F1–F6 more or less subequal in length and slightly shorter than F7 and F8; F1–F6 almost always without mps (except rarely F5 with 1 mps on one of the antennae), F7 and F8 almost always with 2 longitudinal sensilla each (except extremely rarely F7 with just 1 mps); clava 3.0–3.5x as long as wide, a little longer than combined length of F6–F8 or F1–F3, with 7 mps. Mesosoma (Fig. 66) with pronotum mostly weakly sculptured; mesoscutum and scutellum with reticulate sculpture (the cells on anterior scutellum smaller than on mesoscutum or posterior scutellum), midlobe of mesoscutum with a narrow median groove of variable length, from a very short one, just at posterior margin of mesoscutum, to a relatively long groove anteriorly narrowing and extending to about 0.5x length of mesoscutum; metanotum smooth, posterior margin of dorsellum at least slightly rounded; propodeum (Fig. 67) mostly smooth, with median carina usually short (often markedly shorter than median areole or sometimes almost absent, in that case the median areole extending almost to anterior margin of propodeum), lateral carinae not parallel to median carina, each split anteriorly as a very short, Y-shaped carina. Forewing (Fig. 70) 2.6–2.7x as long as wide; disc with a slight brownish tinge throughout, densely setose but bare behind base of submarginal vein, at least slightly (usually notably) truncate apically; longest marginal seta 0.18–0.21x greatest width of wing. Hind wing (Fig. 71) 15–17x as long as wide; disc with a slight brownish tinge and densely setose except basally; longest marginal seta 1.9–2.1x greatest width of wing. Pro- and mesocoxae smooth, metacoxa with reticulate sculpture. Petiole 4.2–4.4x as long as wide, smooth, 1.2–1.3x as long as metacoxa; gaster as in Fig. 69; ovipositor occupying 0.6–0.7x length of gaster, slightly exserted beyond apex of gaster (by at most 0.1x own length), 0.8–0.9x length of metatibia. Measurements (µm) of the holotype: Mesosoma: 430; petiole: 151; gaster: 528; ovipositor: 324. Antenna: radicle: 43; rest of scape: 151; pedicel: 58; F1: 49; F2: 48; F3: 48; F4: 48; F5: 49; F6: 51; F7: 56; F8: 55; clava: 181. Forewing: 1138:418; longest marginal seta: 82. Hind wing: 812:54; longest marginal seta: 104. Legs (given as coxa, femur, tibia, tarsus): fore: 97, 206, 206, 242; middle: 94, 221, 306, 257; hind: 127, 242, 343, 267. MALE. Body length (dry-mounted specimens) 920–1230 µm. Similar to female except for the normal sexually dimorphic features and the following. Antenna (Fig. 72) with scape and pedicel light brown to brown, flagellum brown or dark brown, scape plus radicle 3.9–4.5x as long as wide; propodeum (Fig. 73) occasionally with median carina inconspicuous; forewing (Fig. 74) 2.5–2.7x as long as wide; genitalia as in Fig. 75. <b>Diagnosis.</b> Among the Palaearctic species of <i>Ooctonus</i>, <i>O. saturn</i> sp. n. is most similar to <i>O. vulgatus</i> Haliday in having mps normally only on F7 and F8 of the female antenna, but in the latter the midlobe of mesoscutum lacks an incomplete median groove and the posterior scutellum is mostly smooth except for a weak sculpture at the lateral borders and sometimes also at the anterior margin. In <i>O. saturn</i> the lateral carinae on the propodeum are not parallel to the median carina, and each lateral carina is split anteriorly as a very short, Y-shaped carina that is relatively notably smaller than in <i>O. orientalis</i> Doutt. <b>Hosts.</b> Unknown. <b>Etymology.</b> This species name (a noun in apposition) is that of FC Saturn Moskovskaya oblast’ (Ramenskoye, Ramenskiy rayon, Moskovskaya oblast’, Russia) of the Russian Football (Soccer) Premier League.
