Key to species of Deplorothrips from Australia

1. Metanotum with more than one pair of setae medially ( Figs 1 , 36 ); male sternite VIII with broad pore plate ( Fig. 44 ).................................................................................................. villosus sp.n.

-. Metanotum with one pair of setae medially ( Figs 3–5 ; 33–35); male sternite VIII with pore plate smaller or absent....... 2

2. Head anterior margin yellow to light brown between the eyes ( Fig. 5 ); metanotum longitudinally sculptured; male with no pore plate.................................................................................... virgulatus sp.n.

-. Head uniformly brown; metanotum either reticulate or with no sculpture between the major setal pair; males, where known, with small pore plate on sternite VIII......................................................................3

3. Metanotum strongly reticulate ( Fig. 35 ); male with narrow pore plate extending fully across sternite VIII to lateral margins.............................................................................................. retis sp.n.

-. Metanotum weakly reticulate or with no sculpture between median setal pair; male pore plate on sternite VIII much smaller, not extending to lateral margins......................................................................... 4

4. Antennal segment VIII lanceolate ( Fig. 20 ), microptera with IV as yellow as III, but macroptera with IV brown; IV and V of macroptera with numerous sensory hairs ventrally [pronotal am sometimes capitate; male with small sub-circular pore plate on VIII ( Fig. 40 )]........................................................................... diaphorus sp.n.

-. Antennal segment VIII never lanceolate ( Figs 21–30 ), macroptera without extra sensory hairs on antennal segments IV and V................................................................................................... 5

5. Antennal segment V–VI largely yellow ( Fig. 28 ); male unknown..................................... paspalus sp.n.

-. Antennal segments V–VI uniformly brown or with V slightly paler at base........................................ 6

6. Mid and hind tibiae, also usually antennal segment III, clear yellow............................................. 7

-. Mid and hind tibiae, also antennal segment III, brown or at least washed with brown............................... 9

7. Median area of tergites VI–VIII extensively yellow; pronotal am setae longer than discal setae and about 0.5 times as long as aa setae, blunt to weakly capitate ( Fig. 4 )......................................................... regina sp.n.

-. Median area of tergites VI–VIII almost uniformly brown; pronotal am setae no larger than discal setae..................8

8. Stylets retracted into head half way to po setae ( Fig. 10 ); male sternite VIII with slender transverse pore plate ( Fig. 41 )................................................................................................. howei sp.n.

-. Stylets low in head, wide apart and straight ( Fig. 6 ); male sternite VIII with round pore plate ( Fig. 42 )........ makrus sp.n.

9. Tergite IX setae S1 finely acute and longer than tube................................................. minaei sp.n.

-. Tergite IX setae S1 capitate, rarely bluntly pointed, less than 0.75 times as long tube.............................. 10

10. Male sternite VIII with pore plate strongly transverse, 5–6 times as wide as median length ( Fig. 43 ); both sexes micropterous, but with wing lobe scarcely 20 microns long; antennal segments III and IV each with 2 sense cones.......... mongai sp.n.

-. Male sternite VIII with pore plate transversely oval, less than 2.5 times as wide as median length ( Figs 38, 39 ); if micropterous, then wing lobe at least 50 microns long; frequently with antennal segment III bearing 3 sense cones, and IV with 4...... 11

11. Maxillary stylets retracted to level of po setae, sub-parallel medially in head and less than one fifth of head width apart ( Fig. 13 )........................................................................................ deuae sp.n.

-. Maxillary stylets less deeply retracted, at least one third of head width apart and not parallel medially ( Figs 8, 9 )........ 12

12. Mid and hind tibiae extensively brown; antennal segment III with 3 sense cones, IV with 4; micropterae and macropterae............................................................................................. capitalis sp.n.

-. Mid and hind tibiae yellowish, at least on basal third; number of sense cones commonly different; apterae and macropterae13

13. Both sexes with pronotal am setae acute and scarcely 7 microns long; male sternite VIII pore plate broadly oval ( Fig. 38 )............................................................................................. chydaeus sp.n.

-. Female with pronotal am setae weakly capitate and 15–27 microns long; male sternite VIII pore plate subcircular.................................................................................................... norfuki sp.n.
