Mycterothrips hani sp.n.

( Figs 36–42 )

Female macroptera. Body yellow to brown ( Fig. 36 ); head and thorax yellow with brown lateral margins, mesonotum shaded at anterior margin; abdominal segments I & IX–X yellow, II–VIII brown with posterior margin of 1/3 yellow ( Fig. 38 ); antennal segments I–II brown, the base and apex of segments III–IV yellow, and extreme base of V slightly paler, VI brown, VII–VIII light brown ( Fig. 42 ); all legs yellowish brown, fore wings pale, sometimes with small brown patch on the sub-base and apex of clavus ( Fig. 41 ); prominent body setae yellow.

Head wider than long, slightly rounded at cheeks; ocellar setae I present, setae III situated near anterior margin of posterior ocelli, postocular setae I behind posterior ocelli ( Fig. 38 ). Antennae 8-segmented, segment I with two dorsal apical median setae, II with 3 microtrichial rows on dorsal surface and a mid-dorsal seta below CPS on dorsal surface, III and IV widest at middle and tapering in distal neck-like third, III–VI with some rows of microtrichia on dorsal and ventral surfaces, VIII slightly longer than VII ( Fig. 42 ).

Pronotum wider than long, smooth medially, weakly sculptured with transverse striations on anterior and posterior part, with about 30 discal setae; two pairs of posteromarginal setae, setae I longer than setae II; inner posteroangular setae subequal to outer one ( Fig. 38 ). Mesonotum with CPS anteromedially; median pair of setae situated near or on posterior margin. Metanotum with weak reticulations, but with longitudinal striations laterally, median pair of setae situated at anterior margin, CPS absent ( Fig. 38 ). Fore wing first vein with seven setae at base and two near apex, second vein with setal row complete; posterior fringe cilia slightly wavy; clavus with 5 marginal setae and one discal seta ( Fig. 41 ).

Abdominal tergites and laterotergites without ciliate microtrichia; tergite II with 3 lateral marginal setae; tergites VI–VIII with S4 setae minute; tergite IX with both anterior and posterior pairs of CPS; tergite X split longitudinally in distal half ( Fig. 39 ); sternites without discal setae; sternite VII with median pair of setae situated in front of posterior margin.

Measurements (holotype female in microns). Body length 1379. Head, length 125; width across eyes 156. Ocellar setae III length 53. Pronotum, length 123; maximum width 193; posteroangular setae length, inner 60, outer 58. Metanotum median setae length 37. Fore wing length 754. Antennal segments III–VIII length 48, 55, 38, 48, 12, 18.

Male macroptera. Body paler and smaller than female ( Fig. 37 ); antennae 8-segmented, segment VI almost as long as that of female, with microtrichia on dorsal and ventral surfaces; abdominal tergite VIII with complete posteromarginal comb; IX with one pair of CPS and SB1vestigial ( Fig. 40 ); abdominal sternites without discal setae; hypomere not expanded at apex.

Measurements (paratype male in microns). Body length 1128. Head, length 92; width across eyes 133. Ocellar setae III length 42. Pronotum, length 97; maximum width 152; posteroangular setae length, inner 48, outer 42. Metanotum median setae length 35. Fore wing length 634. Antennal segments III–VIII length 47, 49, 34, 46, 10, 16.

Specimens examined. Holotype female: CHINA, Chongqing City, Xiushan County, Fenghuangshan Forest Park , from Hemiboea subcapitata , 7.viii.2017 (Yajin Li), in collection of Yunnan Agricultural University , Kunming.

Paratypes: 2 females, 2 males, collected with holotype ; 5 females, 2 males from Oplismenus compositus , 7.viii.2017, same locality and collector.

Etymology. In honor of Mr. Yunfa Han for his excellent work on thrips taxonomy in China.

Comments. This species is similar to M. weii , but has antennal segments I–II brown, and the male with SB1 on tergite IX vestigial. In addition, the yellow head with brown lateral margins is unusual among Mycterothrips members.
