Key to Baenothrips species in Australia

1. Metathoracic epimera each with prominent lateral seta (Fig. 1); mesosternal furca present medially; [mid-dorsal pair of anal setae about 0.5 as long as lateral 2 pairs].............................................................. moundi

-. Metathoracic epimera without a stout seta (Fig. 2); mesosternal furca present only laterally........................... 2

2. Only 2 pairs of long anal setae, mid-dorsal pair reduced to minute papillae less than 10 microns long; median pair of anterior cephalic setae scarcely longer than antennal segment III, lateral 2 pairs equal to length of antennal segment VI (Fig. 3); compound eye with no small facets mesad to row of 3 large facets, ventrally usually without a small facet [head and pronotum brown, abdomen uniformly but variably lighter brown with tube yellow]................................... caenosus

-. All 3 pairs of anal setae long, but mid-dorsal pair scarcely one-third as long as lateral pairs; median pair of anterior cephalic setae about as long as antennal segments III+V, lateral 2 pairs at least 1.5 times as long as antennal segment VI (Figs 4, 5); compound eye, mesad of 3 large facets, with row of 4 or 5 small facets, ventrally with one small, isolated facet [Lord Howe Island].............................................................................................. 3

3. Head largely yellow with anterior and anterolateral margins light brown (Fig. 4); anal setae mid-dorsal pair about 0.3 times as long as tube............................................................................... bulbosus sp.n.

-. Head and pronotum uniformly dark brown (Figs 2, 5, 6); anal setae mid-dorsal pair about 0.5 times as long as tube........ 5

5. Fore femora and tibiae uniformly dark brown..................................................... goweri sp.n.

-. Fore femora and fore tibiae uniformly pale, fore tibiae rarely weakly shaded............................. leukos sp.n.
