0C63B13D097A55BC98C5E53D544DCBF8.taxon	description	Description. Measurements: body length ca. 7.1 mm, head length 0.60 mm, head width 0.70 mm, pronotum length 0.60 mm; elytra length 1.30 mm, elytra width 0.41 mm, hindwing length ca. 4.20 mm, hindwing width 1.10 mm; length of protibia 0.37 mm, mesotibia 0.67 mm, metatibia 0.78 mm; length of protarsus ca. 0.44 mm, mesotarsus 0.71 mm, metatarsus 1.10 mm; lengths of 4 - 7 th sternites, respectively 0.77 mm, 0.86 mm, 0.80 mm and 0.86 mm. Female. Body small, narrowly elongate, abdomen arcuate dorsally curved. Color uniformly yellowish brown, in some areas with cuticles darker. Surface leathery, covered with dense, very short protruding pubescence in most areas; legs and thoracic sternites mostly covered with dense setae. Head broadly oval, rather vertical, 1.3 times shorter than pronotum, slightly wider than prothorax. Eyes large, nearly contiguous, occupying almost entire visible surface of head capsule; anterior margin cut out, covering partly of antennal insertion; vertex areas each diverging to form rather triangle shape of eyes. Antennae 11 - segmented, relatively short and thick, 1.2 times as long as head and 1.5 times as long as pronotum; left antenna fully visible and observable, whereas right one partially appressed with only 7 last antennomeres clearly visible; first two antennomeres each slightly transverse, rounded, similar in shape and size, with visible part of first antennomere 1.6 times as wide as its length, of second 1.3 times; 3 rd to 11 th antennomeres forming flagellum with somewhat fusiform club; 3 rd antennomere 1.25 times wider than second, its length almost equal to its width, next two antennomeres approximately equal to it in width, fourth 1.5 times wider than its length, fifth 2 times wider than its length, sixth 1.1 times narrower than 5 th, 1.3 times wider than its length, its width slightly decreasing towards apex, seventh 1.14 times narrower than sixth and 1.17 times wider its length, 8 th approximately equal in length and width, 1.14 times narrower than 7 th, 9 th almost same width, 1.17 times wider than its length, 10 th 1.1 times narrower than 9 th, 1.17 times as long as wide, 11 th cone-shaped, pointed, 1.18 times narrower than 10 th and 2 times as long as wide. Mouthparts partially visible. Clypeus transverse. Mandibles small, inconspicuous. Maxillary palpus with at least 7 short branched appendages (i. e., maxillary palporgan sensu Wheeler 1986), each slightly to moderately longer than penultimate maxillary palpomere. Pronotum short, without maculation, anterior margin rounded; complete longitudinal groove along midline present, but with interruption just behind middle of furrow (see Fig. 4 A, C, ipf). Mesoscutellum relatively narrow, details not visible. Mid- and hindlegs somewhat long, slender; forelegs rather short, robust, moderately thickened, profemora, protibiae, and protarsi approximately equal in length; protibiae without spur, mesotibiae and metatibiae each with one spur (indistinct on mesotibia); procoxae thick, robust, more or less cylindrical; protibiae robust, 4 times as long as wide, protarsi 1.1 times as long as protibiae, 1.35 times as long as pronotum; mesofemora 0.38 times narrower than profemora; mid- and hindlegs long and thin; mesotibiae and metatibia 1.1 times longer than pronotum and 1.8 times as long as protibiae; metacoxae strongly projecting posteriorly, metatibiae feebly curved externally. Tarsi 5 - segmented, metatarsi slightly longer than metatibiae; protarsi with 1 st and 5 th protarsomeres very long, 2 nd and 3 rd short and inconspicuous, approximately equal in length, 4 th protarsomere shorter than each of them; meso- and metatarsi with first segments longest, second ones about 2.3 times shorter than them, 3 rd and 5 th segments slightly shorter than 2 nd, 4 th about 1.8 times shorter than 3 rd. Claws simple, widely separated. Elytra short, 2.45 times as long as pronotum, and 3.4 times as long as its maximum width, each nearly subparallel sided, exposing most part of abdomen; outer elytral margins gently arcuate each with very shallow median emargination (Fig. 4 D, eoe), whereas inner margin straight, not extending beyond metacoxae; surface covered with dense, short obliquely protruding pubescence. Hindwings fully developed, entire, 2.7 times as long as elytra; their apices not covering last two visible abdominal tergites; venation with details remaining unclear, but with visible veins of C-Sc-R, radial-medial (r-m), medial and cubital veins, and part of anal veins. Metaventrite distinctly elongate. Abdomen narrowly elongate, nearly subparallel-sided, weakly tapering posteriorly, uniformly bent dorsally as preserved; abdominal segments II-VII visible. Abdominal segment VIII and ovipositor partially protruding. Styli exposed, weakly clavate, their apices with sparse long bristles. Male unknown.	en	Yamamoto, Shuhei, Nazarenko, Vitaly Yu., Vasilenko, Dmitry V., Perkovsky, Evgeny E.
