( Fig. 41 ) Female microptera : Body and legs brown, tarsi yellow; antennal segment I yellow, II light brown, III–V yellow at base, V–III brown, major setae shaded. Head much longer than wide, dorsal surface almost without sculpture ( Fig. 41 ), ocelli small, cheek setae very weak, postocular setae weakly capitate, shorter than eye length; mouth cone just extending to ferna. Antennal segment III with 2 sensoria, IV with 3 sensoria; IV–VII with parallel-sided pedicel, VIII broadly joined to VII. Pronotum transverse, with no sculpture, 5 pairs of short, bluntly pointed major setae. Fore tarsal tooth acute, nearly as long as tarsal width ( Fig 41 . Mesonotal setae small; metanotum with one pair of small major setae, without sculpture medially. Prosternal ferna not meeting medially; mesopresternum of two slender sclerites, mesoeusternal margin almost straight; metathoracic sternopleural sutures present. Pelta subquadrate; tergites with almost no sculpture, major setae on II–VIII pointed; tergite IX setae S1 and S2 long and finely pointed. Anal setae shorter than tube. Sternites with one row of about 10 small discal setae. Measurements ( holotype female in microns). Body length 1900. Head, length 300; median width 225; postocular setae 50. Pronotum, length 135; median width 280; major setae: am 20, aa 20, ml 20, epim 45, pa 30. Wing lobe 30. Tergite IX setae: S1 100, iS 45, S2 95. Tube length 110. Antennal segments III–VIII length 55, 50, 50, 50, 45, 25. Male : not known. FIGURES 34–42 . Holoengythrips from Australia.

Material studied . Holotype female microptera, New South Wales , Walcha , from Helichrysum leaf, 28.xii.2000 ( LAM 3997 ). Paratypes : Queensland : Brisbane , Mt Glorious , 1 female microptera from dead branch, 19.i.2006 ; Aldershot , 1 female microptera from Eucalyptus bark spray, 18.vii.2011 . Comments . Each of the three micropterae has a very small wing lobe that does not bear any long setae, and each of them also has three ocelli present. Although similar in body structure to tallagandai , this species has three sensoria on the fourth antennal segment and the female fore tarsal tooth is longer.
