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 .
