Key to Japanese species of Aeolothrips

1. Fore wing with sub-basal cross band posteriorly elongated to near apex along posterior margin of wing ( Figs 10 , 21 )....................................................................................................... vittatus

-. Fore wing with two cross bands ( Figs 1 , 15 )................................................................. 2

2. Cross bands on fore wing connected posteriorly ( Fig. 17 )...................................................... 3

-. Cross bands on fore wing not connected ( Fig. 1 ).............................................................. 4

3. Dark area between cross bands not reaching to second vein ( Fig. 17 ); antennal segment IV dark brown; antennal segment VI much longer than wide, 1.8–1.9 times as long as width ( Fig. 40 ).......................................... kurosawai

-. Dark area between cross bands extending beyond second vein ( Fig. 19 ); antennal segment IV almost uniformly yellow; antennal segment VI slightly longer than wide 1.1 times as long as width ( Fig. 40 ).............................. melaleucus

4. Body uniformly dark brown ( Fig. 1 )................................................................. fasciatus

-. Body largely pale, often bicoloured, at least pronotum uniformly pale ( Figs 3, 6 ).................................... 5

5. Pronotum with posteromarginal setae not longer than anteromarginal setae; mesonotum with median pair of setae much shorter and more slender than lateral pairs; head pale with large brown marking medially on dorsal surface; femora shaded dorsally, all tibiae brown ( Fig. 6 ).............................................................................. luteolus

-. Pronotum with some posteromarginal setae much longer than anteromarginal setae; mesonotum with median pair of setae subequal in length or slightly longer than lateral pairs; head uniformly pale, with no brown marking; all legs almost uniformly pale ( Fig. 3 ).............................................................................................. 6

6. Abdominal sternite V with 8 (rarely 7) posteromarginal setae; abdomen almost uniformly pale, indistinctly shaded anterolaterally on some tergites; antennal segment II pale............................................... fukushimensis sp. n.

-. Abdominal sternite V with 6 (rarely 5) posteromarginal setae; abdomen largely pale but bicoloured, tergite X brown, tergites I– VIII with pale brown transverse bands anterolaterally ( Fig. 8 ), antennal segment II shaded.................. setosus sp. n.
