Sakhalinoctonus alexrasnitsyni Davidian, sp. nov. (Figs 1–3) Type material. Holotype: female, PIN 3387 /104. Russia, Sakhalin Island, Dolinsk District, Starodubskoye (PIN). Etymology. This new species is named in honour of Professor Alexander Pavlovich Rasnitsyn, the prominent Russian hymenopterist and palaeontologist, dedicated in celebration of his 85 th birthday. Diagnosis. As stated above, for the new genus. Type locality and horizon. Sakhalin Island, on the beach of Terpeniya Bay, Starodubskoe, Russia. Sakhalinian amber from the Middle Eocene (43–47 Ma). Description. Female. Body length 1.4 mm, antenna length 0.9 mm. Head . Head capsule artificially strongly depressed dorso-ventrally; eyes more or less flattened, with long setae. Scape of antenna short and wide, its length almost equal to maximum apical width. Pedicel rather short and wide, 0.75 times as long as maximum width, as wide as scape. Flagellum entirely with dense and semi-erect setae, length of setae larger than segment width. F1 4.5 times longer than its median width and 1.1 times longer than F2; F2 almost 4.0 times longer than its median width. Remaining segments weakly gradually shortened towards apex and only weakly shorter than F2. Wings . Pterostigma triangular, about 3.5 times longer than its maximum width. Metacarpus (1-R1) about 1.5 times longer than pterostigma. Radial (R, 3-SR, SR1), medial (1-SR+M, 4-M) and parallel (CU1a) veins of forewing almost reaching distal margin of wing. Legs . Femora and tibia of fore and middle legs about 10.0 times longer than their maximum width. Hind femur 13.0 times longer than its medial width; hind tibia 15.0 times longer than its maximum width. Basitarsi of fore and middle tarsi about twice longer than their second segments. Basitarsus of hind leg 3.0 times longer than its second segment. All legs with dense and semi-erect long setae. Metasoma . Petiole long, twice wider apically than basally (lateral view), about 4.0 times longer than its width in middle (subdorsal view). Ovipositor sheaths rather long, weakly curved downward, gradually tapered from base to apex, narrowly rounded at apex, covered predominantly by long setae; sheath almost 6.0 times longer than its maximum width, approximately 0.4 times as long as metasoma (measured from base of petiole to base of ovipositor sheaths). Ventral (inner) margin of sheath with eight–ten long setae, which are gradually shortened to apex of sheath. Pubescence . Head with antenna, body and legs almost entirely covered by long and dense setae. Colour . Body mostly dark brown, palps, four basal segments of antenna, legs, ovipositor and its sheaths yellowish brown. : Published as part of Davidian, Elena M., Manukyan, Andranik R. & Belokobylskij, Sergey A., 2021, A new genus and species of the aphid parasitoids (Hymenoptera: Braconidae: Aphidiinae) from the Eocene Sakhalinian amber, pp. 537-543 in Palaeoentomology 4 (6) on page 541, DOI: 10.11646/palaeoentomology.4.6.3, http://zenodo.org/record/5778548 |
