Adrothrips cotteri Mound, 1970: 444

Described from two female and three male macropterae collected near Canberra, 9.vi.1968, no further specimens have been found at the type locality despite repeated searching. However, as indicated in the list below, this species has been found more recently from three widely separated areas in eastern Queensland, between Brisbane and Charters Towers. The tergites and tube of females are remarkably similar to those of female aureus , and the fore tibia bears a similar papilla-like tubercle at the inner sub-apex. However, the maxillary stylets are shorter and do not cross over each other ( Fig. 13 ). The tube of males is straight sided but the basal half bears reticulation that is similar to that of females. Antennal segment V has the apex asymmetric ( Fig. 3 ), and the mesopresternum is fully transverse ( Fig. 28 ) .
