Key to world genera of Dendrothripinae 

[*based on description; Projectothripoides  omitted as a nomen dubium]

1. Median tergal setal pair much shorter than distance between their bases ( Figs 1, 2View FIGURES 1 – 8)................................. 2

- Median tergal setal pair longer than the distance between their bases ( Figs 6View FIGURES 1 – 8, 12View FIGURES 9 – 19).................................. 5

2. Fore wing apex with 2 small stout setae; antennal segments III and IV with forked sense cones............... Asprothrips 

- Fore wing apex without stout setae, but with long fine cilia; antennal segments III and IV with simple sense cones....... 3

3. Tarsi 1 -segmented; antennae 7 -segmented............................................................. Edissa 

- Tarsi 2 -segmented; antennae 8 -segmented................................................................. 4

4. Pronotum with many small tubercles on anterior and lateral thirds; fore wing posteromarginal cilia straight.... * Parsiothrips 

- Pronotum weakly reticulate without any small tubercles; fore wing posteromarginal cilia slightly wavy........ * Petrothrips 

5. Hind tarsus more than half as long as hind tibia; Old World species.............................. Pseudodendrothrips 

- Hind tarsus no more than one third as long as hind tibia...................................................... 6

6 Pronotum with median transverse groove complete ( Fig. 4View FIGURES 1 – 8); New World species................................... 7

- Pronotum evenly sculptured, median transverse groove if present incomplete medially; Old World species.............. 8

7. Body and wings pale, without pigmentation (but nigripennis  with wings uniformly dark).................... Leucothrips 

- Body and fore wings with various patterns of pigmentation.......................................... Halmathrips 

8. Fore wing apex rounded, without terminal seta.................................................... Dendrothrips 

- Fore wing apex sub-acute to acute, with a prominent terminal seta.............................................. 9

9. Antennae 8 -segmented; head with ocellar setae pair III minute, arising well outside ocellar triangle; pronotum with no long setae.................................................................................. Iranodendrothrips 

- Antennae 9 -segmented; ocellar setae pair III elongate, arising within or on anterior margins of triangle; pronotum with promi- nent posteroangular setae............................................................................. 10

10. Ocellar setae pair III arising between posterior ocelli ( Fig 3View FIGURES 1 – 8); fore wing apex with 2 setae both less than 0.3 as long as width of wing; antennal segments III –IV with elongate apical neck, sense cones extending to at least one-third of the length of succeed- ing segment.............................................................................. Filicopsothrips 

- Ocellar setae pair III arising on anterior margins of ocellar triangle ( Figs 21, 26View FIGURES 20 – 27); fore wing apex with one long seta, as long as or longer than wing width; antennal segments III –IV without an apical neck, sense cones scarcely extending beyond base of succeeding segment......................................................................... Ensiferothrips
