Key to second instar larvae of Panchaetothripinae in Brazil and Argentina

1. Abdominal segment X with 16–18 anal setae ( Fig. 41 View FIGURES 22–42 ).......................................... Retithrips syriacus

-. Abdominal segment X with six anal setae ( Figs 35, 36, 42 View FIGURES 22–42 ).................................................... 2

2. Major dorsal setae clavate, fringed or expanded distally....................................................... 3

-. Major dorsal setae more slender, acute or blunt.............................................................. 9

3. Dorsal setae strongly expanded distally (maximum width of setae at least 3x wider than at the base) ( Figs 15 View FIGURES 1–15 , 20 View FIGURES 16–21 )......... 4

-. Dorsal setae with apex different (if expanded, not remarkably broad)............................................ 5

4. Dorsal setae with concave (crateriform) apex ( Fig. 20 View FIGURES 16–21 ); head with setae D1 inserted posteriorly to D4 setae, D3 with apex expanded......................................................................... Parthenothrips dracaenae

-. Dorsal setae with convex apex ( Fig. 15 View FIGURES 1–15 ); head with setae D1 inserted anteriorly to D4 setae, D3 with apex acute............................................................................................. Bradinothrips musae

5. Abdominal segments IX and X brown, completely sclerotized ( Figs 36, 37 View FIGURES 22–42 ) ( Dinurothrips )........................... 6

-. Abdominal segments IX and X clearer, not fully sclerotized ( Figs 38, 39 View FIGURES 22–42 )........................................ 7

6. Abdominal segments IX 0.7–0.8x longer than wide; abdominal segment X 1.4–1.5x longer than basal width; posterior margin of segment X with teeth medially only, between D1 setae..................................... Dinurothrips hookeri

-. Abdominal segments IX 0.6x longer than wide; abdominal segment X 1.1–1.3x longer than basal width ( Fig. 37 View FIGURES 22–42 ); posterior margin of segment X with minute teeth laterally only................................................ D. vezenyii

7. Dorsal setae emerging from tubercles and with weakly expanded apex (about 1.5x wider than basal quarter) ( Fig. 39 View FIGURES 22–42 ).......................................................................................... Helionothrips errans

-. Dorsal setae not emerging from tubercles and with apex about 2x wider than basal quarter ( Caliothrips )................ 8

8. Setae on meso- and metanotum short, about 4x longer than setae basal width; apex strongly expanded, at least 3x wider than basal quarter width ( Fig. 22 View FIGURES 22–42 )................................................................................................................................................................ Caliothrips phaseoli

-. Setae on meso- and metanotum, more than 10x longer than setae basal width; apex less expanded, 2x wider than basal quarter width ( Fig. 21 View FIGURES 16–21 )....................................................................... Caliothrips insularis

9. Setae on antennal segment III longer than the segment length ( Fig. 6 View FIGURES 1–15 )............................................................................................................................ Brachyurothrips anomalus

-. Setae on antennal segment III as long as or shorter than the segment length ( Figs 7–14 View FIGURES 1–15 )............................. 10
