Key to species of Ensiferothrips

1. Females with fore wing first vein bearing 4 or 5 large dark expanded setae bearing longitudinal ridges ( Fig. 27 ); head with ocellar triangle tuberculate between ocellar setae pair III ( Fig. 26 ); sternites with numerous small tubercles.............. 2

-. Females with fore wing first vein setae all pale; ocellar triangle reticulate; sternites reticulate.......................... 3

2. Basal stem of fore wing first vein with 4 (rarely 5) setae, of which only the distal seta is large and dark, first vein thus with 4 large dark setae; sternite VII median setal pair closer to posterior margin than their length....................... primus

-. Basal stem of fore wing first vein with 4 setae ( Fig. 27 ), of which setae II and IV are larger and darker than I and III, first vein thus with 5 large dark setae; sternite VII median setal pair further from posterior margin than their length...... wallacei sp.n.

3. Female with pronotal and ocellar setae longitudinally grooved and slightly flattened; lateral areas of tergite IV transversely reticulate, posterior reticles with internal longitudinal striae; fore wing apical seta 2/3 as long as width of wing; sternite VII setae arising submarginally....................................................................... secundus

-. Pronotal and ocellar setae setaceous, acute, without longitudinal ridges ( Fig. 21 ); lateral areas of tergite IV transversely striate ( Fig. 24 ); fore wing apical seta longer than wing width; sternite VII with all three setae arising at margin.... lamingtoni sp.n.
