Ramussia captiosum Kurbatov, sp.n. Figs 21–22, 26. MATERIAL. Holotype ♂: SW Sakhalin, 14 km East of Nevelsk, 46°44´33.8´´N 142°03´04.5´´E, rotten Picea , 22.07.2021, S. Kurbatov (ZIN). Paratypes: 3♂ with holotype; 1 ♂, SW Sakhalin, 15 km East of Nevelsk, 46°44´37.5´´N 142°03´35.0´´E, rotten Abies , 24.07.2021, S. Kurbatov (MHNG, ZIN, ZMUM, PCSK). DESCRIPTION. Body 1.35–1.4 mm long, light brown, in fairly fine, dense decumbent pubescence. Head 0.21 mm long, 0.27–0.29 mm wide. Vertexal foveae quite large, distance between them slightly greater than distance from edge of fovea to inner edge of eye at this level. Frontal sulcus intermediate between U- and V-shaped. Anterior edge of the front angular. Eyes large, convex, their diameter in lateral view slightly longer than length of temples. Temples widely rounded. Head dorsally with some minute punctures on frontal anterior edge and on lateral edge above eyes. Antennal tubercles weakly protruding. Antennae with scape subcylindrical; pedicel 1.5 times as long as wide, hardly narrower than scape; antennomeres 3–8 subequally wide, distinctly narrower than pedicel; antennomere 3 slightly longer than wide; antennomeres 4–8 subequal, hardly wider than long, sometimes antennomere 4 as long as wide; antennomere 9 transverse, distinctly wider and hardly longer than 8; antennomere 10 transverse, more than twice as wide as long, barely longer and wider than 9; antennomere 11 more or less conical, wider than 10, longer than 8–10 combined. Pronotum more or less as long as wide (0.29/ 0.30 mm), widest between anterior third and quarter length. Disc variable, either with thin shallow median longitudinal sulcus (in this case pronotal punctuation fine) or without sulcus (then there are several large points there). Short oblique, indistinct sulcus anteriorly from lateral fovea reaching pronotal mid-length. Elytra (0.39–0.40/ 0.43–0.47 mm) with three basal foveae; discal stria not reaching elytral mid-length. Male secondary sexual characters on head and legs not expressed. Sternite 6 ...
