( Figs. 3, 10 , 17, 22 )

Thrips carthami Shumsher, 1946: 184 –185

Female (macropterous): Body and legs yellow; antennal segment I pale, segment II light brownish; fore wings pale; abdominal tergites II–VII yellow usually with brown markings anteriorly ( Fig. 22 ), segment VIII–X usually brown. Antennae 7-segmented, III & IV with forked sense cone. Head wider than long, with two pairs of ocellar setae; pair III just outside ocellar triangle as in palmi ; postocular setae I about as long as ocellar setae III, II & IV minute ( Fig. 3 ). Pronotum wider than long, with two pairs of long posteroangular setae; posterior margin with two pairs of setae. Metanotum with longitudinal sculpture as in flavus ; median setae long, arising behind anterior margin, campaniform sensilla present and close together ( Fig. 10 ). Fore wing first vein with three setae on distal half, second vein with row of about 15 setae; clavus with five setae on marginal vein. Abdominal tergum II with three major dark setae on each lateral margin, and an additional small unshaded seta; posteromarginal comb on tergite VIII complete, fine, slender and regular ( Fig. 17 ); tergite X with a complete median longitudinal split. Pleurotergites and sternites without discal setae.

Male: Much paler and smaller than female; antennal segment II pale; comb absent on abdominal tergite VIII posterior margin; only sternites III and IV with pore plate.

Specimens examined. China: Sichuan, 58 females, 6 males, on Rhododendron simsii , 9.vii.2010.

Remarks. This bicoloured species is larger than palmi , but is structurally similar to that species to which it is probably related. This species is now widespread around India, Pakistan, Himachal Pradesh, Bhutan ( Bhatti, 1980).
