Popis: Anaphothrips oroqeni sp. n. (Figs 6, 16, 22, 28, 34, 39, 45, 49, 53) Female mac. Body and legs yellow; antennal segment I white, segments II and V���IX brown, segment III yellowish, segment IV mainly yellowish with apex pale brown (Fig. 28); fore wings pale and weakly shaded at base (Fig. 34). Head projecting slightly in front of eyes, with distinct transverse reticulations in basal part; eyes about half as long as head length, ventrally with 6 pigmented facets; three pairs of ocellar setae almost equal in length, ocellar setae III arising outside ocellar triangle (Fig. 6); antennae 9-segmented, segments III and IV with forked sense cone, II without microtrichia, VI weakly pedicellate, suture between VI���VII slightly oblique (Fig. 28). Pronotum with weak lines of sculpture, posteromarginal setae longer than other setae (Fig. 16); metanotum sculptured with polygonal reticulations, median setae fine and posterior to anterior margin, campaniform sensilla absent (Fig. 22). Fore wing first vein with about 3 setae basally, 2 setae medially, 2 setae distally and second vein with about 7 setae irregularly spaced, clavus with about 4 veinal setae and one seta at base (Fig. 34). Abdominal tergites smooth medially, lateral thirds with transverse sculpture; tergites II���VII with lobes on posterior margin, large laterally but small medially, campaniform sensilla close to posterior margin (Fig. 39); tergite VIII with posteromarginal comb complete, microtrichia with wide bases, spiracles about 0.4 times as long as length of lateral margin (Fig. 45). Measurements (holotype female in microns). Body length 1448. Antennae length 240; antennal segments I���IX length (width): 20(27), 32(28), 42(20), 40(18), 35(19), 33(20), 11(13), 9(8), 15(5). Head length 135, basal width 159; eyes length 73, width 44; diameter of ocelli 8���11; shortest distance between posterior ocelli 32. Pronotum median length 139, width 172. Fore wing length 676. Female mic. Similar to macropterous female, but forewing undeveloped only about 0.9 times as long as width of pterothorax. Measurements (micropterous female in microns). Body length 1492. Antennae length 250; antennal segments III���IX length: 44, 40, 41, 36, 11, 8, 15. Head length 143, basal width 166. Fore wing length 194. Male mic. Similar to micropterous female but smaller; tergite IX with two pairs of stout median thorn-like setae, setae I about 1.2 times as long as II (Fig. 53); sternites III���VII with small median oval pore plates (Fig. 49). Measurements (micropterous male in microns). Body length 1036. Antennae length 224; antennal segments I���IX length (width): 18(25), 28(25), 41(17), 32(18), 32(18), 33(16), 11(11), 9(6), 14(5). Head length 117, basal width 127; eyes length 54, width 34. Pronotum median length 105; width 155. Fore wing length 114. Abdominal tergite IX thorn-like setae I & II: 19, 16; sternites III���VII pore plates width: 23, 25, 20, 18, 15. Male mac. Similar to micropterous male but smaller and forewing developed. Measurements (macropterous male in microns). Body length 990. Antennae length 207; antennal segments III���IX length (width): 32(15), 33(15), 32(16), 31(16), 11(13), 8(7), 10(5). Head length 112, basal width 133; eyes length 59, width 37. Pronotum median length 97; width 146. Fore wing length 558. Abdominal tergite IX thorn-like setae I & II: 12, 9; sternites III���VII pore plates width: 21, 21, 16, 16, 14. Specimens examined. Holotype female mac., China, Heilongjiang Province, Greater Khingan, Nanwenghe national Nature Reserves (51��22.83'N, 124��34.24'E), 21.vii.2017, from grasses (Jun Wang). Paratypes: 1 female mac., 6 female mic., 1 male mic same data as holotype; Sanjiang Plain (45��01.08'��� 48��27.93'N, 130��13.17'��� 135��05.43'E), 7.vii.2017, 9 female mac., 6 female mic., 1 male mac. from grasses (Jun Wang); Mohe, Tuqiang town (52��56.85'N, 122��46.73'E), 21.vii.2017, 1 female mac., 4 female mic., 1 male mac., 4 male mic. from grasses (Jun Wang), same locality and habitat 1 female mac., 1 female mic., 1 male mac., 1 male mic., 12.viii.2018 (Jun Wang). Distribution. China (Heilongjiang). Etymology. The Latin word oroqeni derived from a minority of Oroqen Ethnic Group, who live in the type locality. Remarks. This new species is closely similar to the Japanese species A. ponokikirmui in having 9-segmented antennae, metanotum without campaniform sensilla and abdominal tergite VIII with complete posteromarginal comb and the microtrichia having wide bases. However, this new species can be distinguished as follows: abdominal tergite X yellowish (Fig. 45) but brown in A. ponokikirmui, tergites II���VII with lobes on posterior margin, but larger laterally (Fig. 39), in contrast to separated serrations in A. ponokikirmui.
