Teuchothrips burroughsi (Girault)

( Figs 21–22 )

Dichaetothrips burroughsi Girault, 1929: 29 .

Described from an unspecified number of specimens taken in “leaf galls” at Boonah in south-east Queensland, this species has not been collected since. The original specimens were mounted by Girault onto a single slide, but two syntypes have been remounted onto two further separate slides. Judging from these two syntypes the species is distinctive with two pairs of long postocular setae, the head constricted behind the eyes, and the genae bear a number of small stout setae ( Fig. 21 ). The maxillary stylets are low in the head and wide apart, the fore tibia bears a small apical tubercle in both sexes. Tergite IX setae S1 are pointed and 0.7 as long as the tube, and setae S2 of the male are similar but about 0.7 as long as setae S1. The fore wing sub-basal setae arise in a straight line, and there are more than 20 duplicated cilia. Antennal segment III bears one sense cone, and IV bears three sense cones. The head shape, stylets and postocular setae distinguish this species from other species of Teuchothrips , and the metanotum is unusual in bearing a group of minute setae anterior to the median major setae ( Fig. 22 ).

Specimens studied. Syntype male and female, Queensland, Boonah [50km southwest of Brisbane, Queensland], November, 1928, in ANIC .
