Key to Podothrips species from Australia

1. Abdominal tergite I comprising median pelta and two lateral sclerites; antennal segment III with one sensorium; fore tibia inner margin with apical tooth, basal to which is a prominent setal-bearing tubercle ( Figure 64 ); fore femur inner margin with pronounced hump or at least rugose with several minute tubercles....... lucasseni

– Abdominal tergite I comprising median pelta only; antennal segment III with two sensoria; fore tibia inner margin without an apical tooth, sub-apical setal-bearing tubercle present but sometimes small; fore femur inner margin smooth... 2

2. Tergite IX setae S1 (both sexes) and S2 (females) capitate....... 3

– Tergite IX setae S1 and S2 acute............... 5

3. Body yellow except head and abdominal segments VIII–X brown (Figure 71); both sexes micropterous, females rarely macropterous........ websteri

– At least thorax dark brown; both sexes macropterous......... 4

4. Body uniformly brown, legs all yellow (Figure 66); metathoracic sternopleural sutures long and well developed............... australis

– Body brown with basal abdominal segments variably yellow; all femora brown, tibiae yellow; metathoracic sternopleural sutures not developed...... regina

5. Head and body yellow except abdominal segments VIII–X brown (Figure 72); antennal segment III with sub-basal ring but no sensoria........ barrowi

– Head brown, body more extensively brown; antennal segment III without prominent sub-basal ring, with two sensoria............... 6

6. Body and legs brown except for apices of tibiae......... orion

– Body distinctly bicoloured, tibiae yellow............. 7

7. Setae S1 on tergite VIII with apices acute; postocular setae acute..... 8

– Setae S1 on tergite VIII with apices capitate; postocular setae usually capitate. 9

8. Body and femora largely brown except abdominal segments I–IV largely yellow; pronotal posteroangular setae acute............. ardis

– Body and femora largely yellow, head and abdominal segments VI–X brown (Figure 70); pronotal posteroangular setae capitate........ ritchiei

9. Prothorax, abdominal segments I–II, and all legs yellow (Figure 69), abdominal tergites III–VI variably yellow with brown area medially........ moundi

– Prothorax and usually all femora brown............ 10

10. Abdominal tergites I–II yellow, III–VI yellow but usually with dark median area, VII–X dark brown (Figure 68)............... xanthopus
