Key to species of Lefroyothrips

[* from description]

1. Fore wing dark at apex, with one shaded band medially and the second at apex (Fig. 23); sternite VII of female with setae S2 arising at margin; male without sternal pore plates........................................................... 2

-. Fore wing pale at apex, with shaded bands near veinal fork and on distal third sub-apically; some species with sternite VII setae S2 of female arising in front of margin; sternal pore plates present on males (where known).......................... 3

2. Abdominal tergites II and VII dark brown, much darker than I and III–VI; segments VIII–X variably brownish yellow to medium brown.................................................................................... fasciatus

-. Abdominal tergites mainly brown, but I and V yellow, VIII sharply yellow on posterior half, IX with a narrow yellow band at anterior margin (Fig. 18)........................................................................... pictus

3. Ocellar setae pair III 80 microns long; body uniformly brown, tergites darker on anterior halves................ * obscurus

-. Ocellar setae pair III less than 50 microns; body extensively pale............................................... 4

4. Ocellar setae pair III very small (Fig. 8), shorter than length of a posterior ocellus, and no longer than postocular setae pair I; postocular setae in an irregular pair of rows [sternite VII posteromarginal setae S2 usually sub-marginal in origin (Fig. 22)]................................................................................................. lefroyi

-. Ocellar setae III longer, at least twice as long as postocular setae I (Figs 9, 24); postocular setae arranged in a single transverse row................................................................................................ 5

5. All antennal segments dark, III with base and apex sharply pale (Fig. 5); metanotal median setae arise well behind anterior margin (Fig. 15); sternite VII setae S2 arise well in front of posterior margin......................... tribulationi sp.n.

-. At least antennal segment III pale (Fig. 6); metanotal median setae arise at anterior margin (Fig. 16); sternite VII setae S2 arise at posterior margin.......................................................................... varatharajani
