Psephenothrips cymbidas View in CoL sp. n.

( Figs 98–105 View FIGURES 98–105 )

Female macroptera. Body length 2.2–2.4 mm. Color brown; Antennal segment I dark brown, same colour as head, II brown, III brownish yellow, IV–VI greyish brown with yellow base, VII brown, VIII dark brown; all femora brown, fore tibiae yellow, mid tibiae greyish brown with distal half yellow, all tarsi yellow; fore wings pale brown with a darker stripe; major body setae hyaline.

Head square ( Fig. 98 View FIGURES 98–105 ), po setae blunt, arising at middle of dorsum, about same length as eyes; maxillary stylets retracted to eyes posterior margins, touching medially and sometimes overlapping; antennal segment III and IV longest, about 1.3 times length of segment II, segment VIII cornical and shorter than VII ( Fig. 105 View FIGURES 98–105 ). Pronotum with 5 pairs of major setae ( Fig. 99 View FIGURES 98–105 ), all blunt; epim, pa and pm setae brown with white ends; aa setae and am setae about equal in length; mesopresternum narrowly connected or separated into 2 parts ( Fig. 101 View FIGURES 98–105 ); metanotum sculptured with longitudinal striae and irregular reticles ( Fig. 100 View FIGURES 98–105 ); MSS present though short; fore wing with 12 duplicated cilia. Pelta triangular, blunt laterally ( Fig. 102 View FIGURES 98–105 ), 1 pair of CPS; tergite II laterally with 4 accessary setae ( Fig. 103 View FIGURES 98–105 ); tergites II–VII with 2 pairs of wing retaining setae; tube shorter than head ( Fig. 104 View FIGURES 98–105 ).

Measurements (holotype in microns). Body length 2400. Head, median length 300; greatest width 285; postoc- ular setae length 90. Antennal segments (L/W) I 45/37, II 50/32, III 90/30, IV 70/35, V 60/33, VI 70/30, VII 55/23, VIII 35/10, total L 475. Pronotum, median length 160; greatest width 400; am setae 52, aa setae 50. Fore wing length 900. Pelta, length 110; width 170. Tergite IX setae S1 220; tube length 220.

Male macroptera. Body length 2.3 mm; colour and shape similar to female.

Specimens examined. Taiwan, Puli (Nantou), holotype female from flower of Cymbidium , 17.iii.2000; paratypes 5 females, 3 males with same data as holotype .

Etymology. In reference to Cymbidium on which it was collected.

Comments. This species is similar to strasseni in having setae S1 on tergite IX almost as long the as tube, and the pronotal aa and am setae about equal in length. However, the colour is distinctive, with the fore and mid tibiae yellow and the fore wings pale brown distinguishing this species from strasseni and the other species.
