Anaphothrips populi Zhang & Tong, 1992: 71 .

This species was originally described in Chinese based on macropterous females, but a brief English description of a paratype was provided more recently ( Cui, Xi & Wang 2017). This species is distributed widely in northern China.

Male mac. Similar to macropterous female, but smaller; sternites III–VII each with a small median curves or oval pore plate ( Fig. 50 ); tergite IX with two pairs of thorn-like setae medially, setae I 1.6 times as long as II ( Fig. 54 ).

Measurements (one male in microns). Body length 888. Antennae length 202; antennal segments I–IX length(width): 18(26), 24(25), 32(18), 31(17), 31(18), 31(18), 9(11), 8(7), 13(5). Head length 92, basal width 135; eyes length 56, width 40. Pronotum median length 100; width 163. Fore wing length 541. Abdominal tergite IX thorn-like setae I & II: 19, 12; sternites III–VII pore plates width: 23, 24, 22, 16, 16.

Specimens examined. China, Henan Province, Baiquan, Baoding Mountain , 21.vi.1979, 1 female mac. paratype from Populus (Shengfu Shi) . Jilin Province, Changchun City , Heping campus of Jilin University (43°55.27′N, 125°16.36′E), 1 male and 3 females, 04.vi.2018, from grasses (Yanze Cui) . Heilongjiang Province, Daqing City, Yinlang ranch (46°33.78′N, 124°50.18′E), 2 females mac., 13.vi.2018, from grasses (Jun Wang) ; Ningxia Hui Autonomous Region, Yinchuan City, Suyukou National Forest Park (38°45.91'N, 105°55.95'E), 1 female mac., 27.vii.2018, from grasses (Yanze Cui) .

Distribution. China (Jilin, Heilongjiang, Ningxia, Henan, Gansu).

Remarks. This species is similar to A. incertus in appearance and their differences have been provided ( Cui, Xi & Wang 2017). The females are also similar to those of A. badius in posterior margin of tergite VIII with complete long comb, body uniformly dark brown, posterior margin of tergites usually with lobes at each side. However, in populi the fore wing first vein bears 13–15 setae and the second vein 11–14 setae ( Fig. 35 ), in contrast in A. badius the first vein bears 9–11 setae and the second vein 6–10 setae. Moreover, populi males can be distinguished from those of badius by sternites III–VII each with a pore plate ( Fig. 50 ) and tergite IX with two pairs of median, large thorn-like setae ( Fig. 54 ), whereas in A. badius a pore plate is present only on sternites III–VI and tergite IX has two pairs of, smaller spine-like median setae.
