Mycterothrips cangshanensis sp. n.

( Figs 10–17 )

Female macroptera. Body brown ( Fig. 10 ); antennae brown with the base and apex of segment III pale ( Fig. 15 ); all legs brown with tarsus yellowish brown; fore wings brown except base pale, clavus brown with apex yellow ( Fig. 16 ); body setae strong and dark brown.

Head wider than long, slightly rounded at cheeks; ocellar setae I present, setae III situated between posterior ocelli, postocular setae I the longest ( Fig. 12 ). Antennae 8-segmented, segment I with two dorsal apical median setae, II with microtrichial rows and a mid-dorsal seta below CPS on dorsal surface, segments III and IV with sense cone forked and tapering in distal neck-like third ( Fig. 15 ).

Pronotum wider than long, dorsal surface smooth; two pairs of posteromarginal setae, setae I slightly longer; two pairs of posteroangular setae, setae I subequal to setae II. Mesonotum with CPS anteromedially; median pair of setae near posterior margin. Metanotum with reticulate striations, but with irregular longitudinal striations laterally, median pair of setae situated at anterior margin, CPS absent ( Fig. 12 ). 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. 16 ).

Abdominal tergites without ciliate microtrichia on lines of sculpture, smooth medially, but posterior margin of laterotergites often partly irregularly dentate; tergite II with 3 lateral marginal setae, tergites VI–VIII with S4 setae minute; tergite VIII with complete posteromarginal comb ( Fig. 13 ); tergite IX with both anterior and posterior pairs of CPS; tergite X with longitudinally split in distal 1/3; sternites without discal setae; median pair of setae on sternite VII situated in front of posterior margin.

Measurements (holotype female in microns). Body length 1477. Head, length 98; width across eyes 161. Ocellar setae III length 68. Pronotum, length 137; maximum width 196; posteroangular setae length, inner 66, outer 66. Metanotum median setae length 52. Fore wing length 960. Antennal segments III–VIII length 62, 54, 32, 37, 10, 16.

Male macroptera. Body paler and smaller than female ( Fig. 11 ); antennae 8-segmented, segment VI with microtrichia on dorsal and ventral surfaces, almost as long as that female; abdominal tergite VIII with complete posteromarginal comb; tergite IX with one pair of CPS, SB1 setae vestigial ( Fig. 14 ); sternite without discal seta; hypomere expanded at apex ( Fig. 17 ).

Measurements (paratype male in microns). Body length 1115. Head, length 95; width across eyes 137. Ocellar setae III length 45. Pronotum, length 102; maximum width 161; posteroangular setae length, inner 55, outer 55. Metanotum median setae length 34. Fore wing length 716. Antennal segments III–VIII length 55, 52, 30, 38, 8, 16.

Specimens examined. Holotype female: CHINA, Yunnan Province, Dali City, Cangshan Mountain, from Parthenocissus quinquefolia , 15.vii.2018 (Hui Liu), in collection of Yunnan Agricultural University , Kunming.

Paratypes: 6 females, 2 males, collected with holotype .

Etymology. The new species is named after collected place.

Comments. This new species is similar to to M. weii from Iran, with ocellar setae I present, mesonotum with CPS anteromedially, abdominal tergites without ciliate microtrichia on lines of sculpture and tergite II with 3 lateral marginal setae ( Mirab-Balou et al. 2011), but this new species has the body brown, ocellar setae III situated between the posterior ocelli, posterior margin of abdominal laterotergites often partly irregularly dentate and SB1 setae degenerate on tergite IX of male.
