description: Key to Lissothrips species from Australia and New Zealand
1. Antennal segments VII and VIII broadly joined (Fig. 3), segment III with one sense cone; fore tarsus with a tooth, although this is sometimes small and directed ventrally.................................................................. 2
-. Antennal segment VIII slender and narrowed to base (Figs 1–2, 4–7), segment III with no sense cone; fore tarsus usually without a tooth in both sexes................................................................................ 3
2. Pelta broadly D-shaped (Fig. 17); pronotal am setae less than 0.5 as long as aa setae; New Zealand and Australia .... dentatus
-. Pelta reduced to irregular sub-circular sclerite; pronotal am and aa setae equally long and slender; New Zealand .... dugdalei
3. Head with po setae capitate (Figs 8–10); both sexes micropterous with wing lobe more than 25 microns long (Fig. 18); male [where known] with no pore plate on sternite VIII........................................................... 4
-. Head with po setae finely acute (Figs 11–13); apterous, or micropterous with wing lobe no more than15 microns (Fig. 21) [one macroptera known]; male sternite VIII pore plate present or absent.............................................. 6
4. Antennal segment III wider than long, almost disc-shaped (Fig. 2)...................................... discus sp.n.
-. Antennal segment III longer than wide, laterally convex (Figs 1, 4)............................................. 5
5. Antennal segment IV with 2 stout sense cones; maxillary stylets about 1/3 of head width apart; wing lobe 25–30 microns long; pelta transverse (Fig. 16), extending across 0.7 of width of tergite II; female fore tarsus with no tooth....... corticosus sp.n.
-. Antennal segment IV with 3 slender sense cones; maxillary stylets about 1/4 of head width apart; wing lobe 40–60 microns long; pelta D-shaped (Fig. 19), extending across 0.5 of width of tergite II; female fore tarsus with minute tooth... hypni sp.n.
6. Mesopresternum transverse and entire (Fig. 26); antennal segment III scarcely 1.3 times as long as wide (Fig. 6); male with no pore plate on sternite VIII; both sexes with minute fore wing lobe 10–15 microns long bearing one major seta...................................................................................................... taverneri sp.n.
-. Mesopresternum absent or reduced to two lateral sclerites (Fig. 25); antennal segment III more than 1.5 times as long as wide (Figs 5, 7); male sternite VIII with or without pore plate medially; both sexes fully apterous......................... 7
7. Male sternite VIII without pore plate; female with pronotal am scarcely 3 times as long as pronotal posterior discal setae (Fig. 11), male am setae about 20 microns long............................................................. gersoni
-. Male sternite VIII with small oval or broadly transverse pore plate; both sexes with pronotal am setae about 5 times as long as posterior discal setae (Figs 13, 15)....................................................................... 8
8. Male sternite VIII with small oval pore plate medially (Fig. 27); mesonotum of both sexes usually with pair of long setae laterally (Fig. 20)............................................................................ tallagandai sp.n.
-. Male sternite VIII with narrow elongate pore plate medially (Fig. 28); mesonotum never with lateral setae elongate................................................................................................. thomsonae sp.n.
