Key to the species of Rohrthrips from Cretaceous amber

1. From Lebanese amber; fore wings with two veins................................................... R. libanicus

- From Burmese amber; fore wings with one vein............................................................. 2

2. Tube short and bulky (length: basal width about 2.3–2.5)...................................................... 3

- Tube long and slender (length: basal width about 3.5–5.1)..................................................... 5

3. Head very short, about 1.4 times wider than long; antennal length about 0.3 of body length; small species (body length <1.3mm)................................................................................... R. breviceps

- Head longer; larger species (body length> 1.5mm)........................................................... 4

4. Head about 1.25 times wider than long; wing vein distally dark; very large species (body length over 2.1mm)..... R. maryae

- Head about as long as wide; wing vein pale along entire length; smaller species (body length about 1.6mm)..................................................................................................... R. patrickmuelleri

5. Head clearly longer than wide; epimeral setae very long (> 170)...................................... R. burmiticus

- Head wider than long; epimeral setae shorter (<120)......................................................... 6

6. First vein short, hardly reaching last quarter of fore wing, apically split, with two terminal setae; tube very long and slender (length/basal width about 5.1); antennal segment III conspicuously long (about 100); very large species (body length over 2.1mm)................................................................................. R. schizovenatus

- First vein longer, reaching costa close to apex of fore wing, not diverged into two branches; tube and antennal segment III shorter; smaller species (body length about 1.5mm)................................................... R. jiewenae
