Sakhalinoctonus alexrasnitsyni Davidian, sp. nov.</p> <p>Etymology. The new genus name is composed from Sakhalin, name of island where the studied amber was collected, and part of the aphidiine genus name “ Monoctonus ”. The gender is masculine.</p> <p>Diagnosis. Mandible bidentate; maxillary palpus 4-segmented. Antenna (Fig. 2) 12-segmented, filiform, densely pubescent. Mesoscutum (Figs 1, 2) probably with complete notauli. Propodeum with large median areola delineated by prominent carinae. In forewing (Fig. 3A, B), pterostigma narrowly triangular; metacarpus (1-R1) relatively hardly perceivable, not reaching wing apex. Radial (r, 3-SR, SR1), medial (1-SR+M, 2-M, 3-M) and parallel(CU1a) veins of forewing long and almost reaching distal margin of wing. First and second radiomedial (submarginal) cells fused together with discoidal (discal) cell and formed united large medial cell. Second transverse anal vein (a) present, but very fine. Hind wing without closed cells. Legs (Figs 1, 2) long; hind leg about as long as body, covered by dense and semi-erect setae (as those on body). Petiole of metasoma (Figs 1, 2) long, slightly widened towards apex, about 4.0 times as long as its width medially. Ovipositor weakly curved down, wide basally, acuminate towards apex and with subapical dorsal notch. Ovipositor sheath (Fig. 3C) relatively long, about 6.0 times longer than maximum width, gradually tapered from base towards apex and very narrowly rounded at apex, weakly curved downward, covered by mainly long setae.</p> <p>Remarks. Sakhalinoctonus gen. nov. is the most similar to the fossil genera Protacanthoides Mackauer, 1961 (type species: Trioxys obscuriformis Quilis, 1940 = Trioxys fossilis Mackauer, 1959) and Promonoctonia Starý, 1973 (type species: Aphidius quievreuxi Quilis, 1940) by the small number of antennal segments, presence of the closed medial cell in the forewing, and downward curved and taped apically ovipositor sheaths.</p> <p>Protacanthoides and Promonoctonia are characterised by a 13-segmented thick antenna, third abscissa of radial vein (SR1) of forewing rather short and not reaching distal margin of wing, second (3-SR) and third (SR1) abscissae of radial vein subequal in the length, and the ovipositor sheath curved downward. In addition, Protacanthoides fossilis has metasomal petiole subtriangle with approximately equal its length and maximum width, which is smooth and without protruding spiracular tubercles; ovipositor sheath rather short, evenly curved downward and tapered towards its apex, acuminate apically, about 0.15 times as long as metasoma. Unfortunately, the information about the condition of notauli, propodeum and pubescence of the ovipositor sheath was not visible in this specimen. On the other hand, Promonoctonia quievreuxi is also characterised by the following additional features: notauli missing; propodeum smooth and without delineated areola; metasomal petiole very short and wide; ovipositor sheaths claw-shaped, with long and wide its basal part and short and narrow apical part, approximately 3.0 times longer than its maximum width and 0.15 times as long as metasoma.</p> <p>The differences between Sakhalinoctonus gen. nov. and similar fossil genera are shown in the key below.</p> <p>Key to fossil aphidiine genera with curved down ovipositor sheaths</p> <p>1.
