description: <i>Brakothrips eucalypti</i> sp. n. (Figs 1–5)<i>Male aptera</i>. Body light brown with variable areas of yellow; head yellow laterally and between eyes, pronotum yellow laterally, also notopleura; pelta and posterior margin of metanotum yellow, also tergites II–III lateral margins; antennae brown with apical third of segment III yellow; tibiae with distal third or fifth yellow, femora variable. Head with compound eyes much larger dorsally than ventrally, ocelli absent (Fig. 2); vertex reticulate medially, with about 30 pairs of small setae including 2 longitudinal rows between the eyes; postocular setae arising on genae (Fig. 1), with apex as broadly expanded as setal length; mouth cone not extending beyond fore coxal hind margin. Antennae 8-segmented (Fig. 3), III with one sense cone, IV &amp; V each with 2 sense cones; VII &amp; VIII closely joined, VII broadly joined to VI, IV–VI sharply pedicillate, III with basal flange over pedicel. Pronotum with many short stout setae, with 3 or 4 pairs of short, capitate major setae, midlateral pair variable, anteromarginal pair not developed; notopleural sutures complete. Fore femora and fore tarsal tooth of largest male enlarged (Fig. 1), but these are more slender in small males. Mesonotum slender, transverse, lateral setae minute. Metanotum irregularly reticulate with at least 40 small bluntly pointed setae (Fig. 4). Prosternal basantra absent, ferna transverse and fused medially; mesopresternum absent or reduced to pair of small lateral triangles, mesoeusternal anterior margin entire. Pelta transverse, reticulate on posterior third (Fig. 4); tergite II with about 40 bluntly pointed discal setae, III–VIII with fewer discal setae and these are more acute on the more posterior tergites; II–VII each with pair of short, broadly capitate posteromarginal setae and mesad of these a pair of small curved marginal setae (Fig. 5); tergite IX setae S1 and S2 capitate, shorter than basal width of tube, S3 long and acute. <b>Measurements</b> (holotype male in microns). Body length 1350. Head, length 175; maximum width 160; postocular setae 10. Pronotum, length 150; width 190; major setae, aa 15; epim 25, pa 25. Tergite IX setae, S1 25; S2 25; S3 100. Tube length 125. Antennal segments III–VIII length, 45, 48, 45, 45, 25, 23. <i>Female aptera</i>. Similar to male in colour and structure; length of fore tarsal tooth less than half tarsal width. <b>Material examined.</b><i>Holotype</i> male aptera, <b>AUSTRALIA, Australian Capital Territory</b>, Weston, Oakey Hill (35°20′16″S, 149°04′05″E), from young exfoliating twigs of <i>Eucalyptus cinerea</i>, 21.iv.2011 (LAM5494). <i>Paratypes</i>: taken with holotype, 5 females, 2 males; from same tree as holotype, 5 females, 3 males, 18.ii.2012 (LAM5553).
