Key to species of Pseudodendrothrips in Japan and Taiwan

1. Head pale or slightly shaded between antennae ( Fig. 10 ); fore wing uniformly pale............................... mori

-. Head distinctly shaded at least between antennae ( Figs 4–9 ); fore wing shaded to dark ( Figs 4, 5 ) or with brown spots ( Figs 8, 9 ) or longitudinal shaded line ( Figs 6, 7 ), never uniformly pale.................................................. 2

2. Fore wing uniformly dark ( Fig. 4 ); head pale with dark area between antennae, mesothorax to abdomen almost uniformly pale.................................................................................................... 3

-. Fore wing not uniformly dark, at least with pale area at base ( Figs 6, 8 ); head to abdomen with brown markings, not uniformly pale................................................................................................ 4

3. Pronotum usually with longitudinal brown bands laterally ( Fig. 5 ); abdominal tergite IX with S3 setae distinctly stouter than remaining posteromarginal setae ( Fig. 43 ) [ Japan, Okinawa]................................................. darci

-. Pronotum uniformly pale ( Fig. 4 ); abdominal tergite IX with S3 setae as slender as remaining posteromarginal setae ( Fig. 42 )............................................................................................... bhattii

4. Pronotal posteromarginal setae long and stout and similar to posteroangular setae; abdominal tergites with numerous small wrinkles between small longitudinal ridges arising from transverse lines; sternites III–VI with small longitudinal ridges arising from transverse lines throughout; fore wing shaded but without brown spots or longitudinal line [ Taiwan]......... fumosus

-. Pronotal posteromarginal setae much smaller than posteroangular setae ( Fig. 23 ); abdominal tergites with dots, but no wrinkles between small longitudinal ridges arising from transverse lines ( Figs 28 , 38 ); sternites without small longitudinal ridges arising from transverse lines at least medially ( Fig. 30 ); fore wing with brown spots or longitudinal line....................... 5

5. Abdominal tergites distinctly bicoloured ( Figs 6, 7 ); fore wing pale with brown longitudinal line medially [ Japan, Okinawa; Taiwan]....................................................................................... lateralis

-. Abdominal tergites laterally with two brown markings, but not bicoloured ( Figs 8, 9 , 38–39 ); fore wing pale with brown spots at base of setae [ Japan, Honshu].............................................................. maculatus sp.n.
