Scirtothrips casuarinae Palmer & Mound

Scirtothrips casuarinae Palmer & Mound, 1983: 512 ­513.

In common with S. solus , the only other species in this genus with seven instead of eight antennal segments, S. casuarinae appears to be associated with the foliage of young Casuarina plants [ Casuarinaceae ]. Although taken at several sites in eastern New South Wales and Queensland, the species has been collected rarely. As in S. solus , the tergal median discal setae are further apart than in many Australian Scirtothrips species, and the metanotum has weak equiangular reticulation with the median setae well behind the anterior margin. The forewing posteromarginal cilia are mainly straight in this species, but two or more cilia near the base of the wing are weakly undulating. The male bears a pair of long dorsally­curving drepanae on the ninth tergite, but the aedeagus does not bear any spines or stout setae.
