Adrothrips systenus Mound, 1970: 451 View in CoL

Described originally from three female and two male micropterae taken at Moree from Casuarina glauca View in CoL , this species remains known from few specimens. The maxillary stylets of the slide-mounted type specimens are possibly slightly out of their natural position, and probably are more deeply retracted into the head capsule in life ( Fig. 18 View FIGURES 11–19 ). The mouth cone is long and pointed, and postero-lateral flexures of the stylets are rather similar to the condition in madiae View in CoL sp.n., each with two curves twisted into an irregular figure-of-eight. Antennal segment V apex is almost symmetrical, the prosternal ferna are slender, transverse and almost continuous medially, and the mesopresternum is eroded to two slender lateral triangles with the mesoeusternal border transverse. The metanotum and tergites bear many short blunt pale setae ( Fig. 27 View FIGURES 20–27 ), and the tube is slightly enlarged in the basal third ( Fig. 37 View FIGURES 28–39 ) .

Specimens studied. Holotype female microptera, New South Wales, Moree 50km north, from Casuarina glauca , 16.vii.1968, in ANIC; Queensland, Dalby, Broadwater Lake, from Casuarina cristata , 1 male microptera, 8.iii.2006, in QDPC.
