1. Fore wings grossly inflated in basal 2/3 (Fig. 3); antennal segment VIII about 3.5 times longer than width of segment II (Fig. 34)...................................................................................... Arachisothrips
-. Fore wings not inflated, generally linear and flat; antennal segment VIII less than 2.0 times longer than width of segment II (Figs 35–47)......................................................................................... 2
2. Fore wings with protruding calosities and surface covered with small tubercles basally (Fig. 91), but with microtrichia distally......................................................................................... Retithrips

4. Antennae 7-segmented; fore wings broad, reticulate with feather-shaped setae (Fig. 90)…................ Parthenothrips
-. Antennae 6- or 8- segmented; fore wings without reticulation, slender and with setae of different shapes (Figs 80–89)..... 5
5. Body surface almost without reticulation, except for part of metanotum (Figs 48, 68); fore wings with long, dark setae (Figs 6, 7); antennal segment IV prolonged in a tapered apical neck, antennal segment III with long and tapered basal part (Fig 35); tergite X without longitudinal division (Fig. 97)................................................ Brachyurothrips
