Helionothrips lushanensis sp. n. is described from China. The new species is characterised by the head entirely dark brown, antennal segments I–VIII almost uniformly yellowish brown and III–IV strongly vasiform, metascutellum without produced posterior margins, and male has no pore plate on the abdominal sternites.
Helionothrips , new species, Thripidae , thrips
Helionothrips Bagnall, 1932, is one of the most species rich taxa in the subfamily Panchaetothripinae, currently comprises 28 described species in the world (
The thrips were collected by beating vegetation over a white plastic tray using a stick, and then sorted and preserved in 90% alcohol. Examined specimens were mounted in Canada balsam using the method outlined by
Holotype female (in SCAU): CHINA, Jiangxi province, Jiujiang City, Mt. Lushan (29°33'N, 115°59'E), collected from older leaves of Ligustrum sinense (Oleaceae), 9.xi.2015, leg. Xiaoli Tong.
2 males from older leaves of Ligustrum sinense (Oleaceae), 4 males from older leaves of Viburnum sp. (Caprifoliaceae), 1 female from older leaves of Rhododendron simiarum (Ericaceae), all taken with holotype. Hunan province, Liuyang City, Daweishan National Forest Park (28°25'N, 114°06'E), 1 male from older leaves of Rhododendron latoucheae (Ericaceae), 15.viii.2016, leg. Zhaohong Wang.
Both sexes macropterous; body dark brown; head entirely dark brown; antennal segments I–VIII yellowish brown; fore wing brown with two pale bands. Head entirely reticulate without internal wrinkles within the reticules; antennae 8-segmented, segments III and IV strongly vasiform with forked sensoria, that on IV reach near the apex of V. Pronotum, meso- and metanotum completely reticulate, all lacking internal wrinkles within the reticles. Antecostal line on abdominal tergites III–VIII divided into broad arched sculpture with heavy anterior margin; tergite VIII with complete comb of microtrichia on posterior margin. Male similar to female in structure and colour but smaller; abdominal sternites without pore plates.
Female (macropterous): Body dark brown (Fig.
Head approximately twice as wide as long, sculptured with polygonal reticulations and without internal wrinkles within the reticules (Fig.
Pronotum wider than long, slightly ovoid (Fig.
Abdominal tergites I and II covered with polygonal reticulations, III–VIII entirely reticulate except for the submedian smooth areas behind campaniform sensilla, with weak internal wrinkles within posterolateral reticules; antecostal line on tergites III–VIII divided into broad arched sculpture with heavy margin (Fig.
Measurements (holotype female, in microns). Distended body length 1870. Head length (width) 100 (210); eye length (width) 70 (50). Pronotum length (width) 175 (250). Fore wing length 1040. Antennal segments I–VIII length (width) as follows: 26(25), 40(33), 65(29), 53(33), 40(25), 31(21), 10(9), 30(6).
Male (macropterous) (Fig.
Measurements (paratype male, in microns). Distended body length 1570. Head length (width) 100 (175); eye length (width) 60 (40). Pronotum length (width) 140 (200). Fore wing length 840. Antennal segments I–VIII length (width) as follows: 20(22), 35(29), 58(27), 48(33), 33(24), 28(20), 8(9), 30(5).
The specific epithet is named after the type locality, Mt. Lushan, Jiujiang City, Jiangxi province, China.

The new species is most similar to H. errans (Williams) in colour and structure, particularly in the pronotum lacking internal wrinkles within the reticules and abdominal tergite VIII having a complete comb on its posterior margin, but it can be distinguished from the latter by (1) head entirely dark brown (head anterior of fore ocellus yellow in H. errans); (2) antennal segments I–VIII almost uniformly yellowish brown (antennal segments I and III-V yellow, II and VI brown in H. errans); (3) antennal segments stouter, especially III and IV strongly vasiform, segment IV approximately 1.6 times as long as wide (in H. errans, the antennal segments slender, III and IV stalk-like, segment IV more than twice as long as wide); (4) metascutellum normal, lacking produced posterior margins (metascutellum with posterior margins produced in H. errans) and (5) male has no pore plate on the abdominal sternites (while the male has pore plates on sternites VII and VIII in H. errans).
