Strepterothrips apterus Okajima

( Fig. 36 )

Strepterothrips apterus Okajima, 1976: 14 .

Described from four females and three males, all apterae, this species is distinguished by the short, dark brown third antennal segment that bears one small, slender sense cone, but with two sense cones on the fourth segment. It is closely related to the new species barbatus described below, from which it differs as indicated in the key above. Three other new species described below from Australia have no sense cones on segment III but have two on segment IV, whereas orientalis has one sense cone on segment III and three on segment IV.

Material studied. Australia: New South Wales, near Walgett, holotype female, paratype male from Eucalyptus leaf litter, 5.vi.1968 ( ANIC).
