Aduncothrips kailiensis sp.n.

( Figs 29–36 )

Female macroptera. Body uniformly brown ( Fig. 29 ); antennal segment I dark brown, II pale, II–IV yellow but shaded at extreme apex of III and distal third of IV, V–IX brown ( Fig. 34 ); fore wings with a long longitudinal dark band, pale at subbase and apex, claves brown ( Fig. 31 ); all legs brown, with the base of hind tibiae pale. Head wider than long, sculptured with closely transverse striae; postocular setae in two rows but irregularly arranged ( Fig. 30 ). Maxillary palp segment II subdivided ( Fig. 35 ). Antennal segments III–IV sensorium vermicular and around apex, with internal markings ( Fig. 33 ). Pronotum wider than long, sculptured with transverse striae, with about 40–50 discal setae and 3 pairs of posteromarginal setae slightly shorter than discal setae, except S2 stouter. Mesonotum with closely transverse striate, with a few wrinkles between sculpture lines on posterior part; lateral and posteromedian setae short and stout; anteromedian CPS absent ( Fig. 32 ). Metascutum sculpture with internal markings between sculpture lines, anterior-medially with closely transverse striae, posterior area with reticulation, median and submedian pairs of setae situated near middle, submedian pair slightly behind, CPS present ( Fig. 32 ). Abdominal tergite I with transverse lines, II-VIII smooth medially, VI-VIII with lateral transverse lines weakly. Sternites II–VI with 3–4 pairs of posteromarginal setae, VII with 5 pairs of posteromarginal setae in front of posterior margin, 2 pairs of accessory setae between S1 and S2; Sternites V–VIII each with 1–4 pairs of discal setae ( Fig. 36 ).

Measurements (holotype in microns). Body length 1753; head length 141, width 188. Pronotum length 171, width 210. Fore wing length 754, median width 111. Antennal segments I–IX length: 56, 50, 81, 83, 60, 48, 34, 16, 15.
