Holoengythrips namadgi View in CoL sp.n.
( Figs 38 View FIGURES 34–42 , 47 View FIGURES 43–54 , 60 View FIGURES 55–62 , 67 View FIGURES 63–72 )
Female aptera. Body and legs brown, tarsi yellowish brown; antennae brown, III yellow at base, major setae shaded. Head longer than wide ( Fig. 38 View FIGURES 34–42 ), dorsal surface with weak sculpture, ocelli absent, cheek setae weak, postocular setae weakly capitate and longer than eye length; mouth cone not extending to ferna. Antennal segments III and IV each with 2 sensoria; IV–VI with parallel-sided pedicel, VII with broad pedicel, VIII slightly constricted at base. Pronotum transverse, with no sculpture, am setae pointed, remaining 4 pairs capitate. Fore tarsal tooth minute, at inner apex. Mesonotal setae all small; metanotum with one pair of small major setae, without sculpture medially ( Fig. 47 View FIGURES 43–54 ). Prosternal ferna not meeting medially; mesopresternum of two small lateral sclerites, mesoeusternal margin eroded medially ( Fig. 60 View FIGURES 55–62 ); metathoracic sternopleural sutures present. Pelta anterior margin rounded ( Fig. 47 View FIGURES 43–54 ); tergites with almost no sculpture, with one pair of very small, straight wing-retaining setae; major setae on II–VIII weakly capitate; tergite IX setae S1 and S2 pointed. Anal setae about as long as tube. Sternites with one row of about 6 discal setae.
Measurements (holotype female in microns). Body length 1950. Head, length 225; median width 170; postocular setae 55. Pronotum, length 130; median width 225; major setae: am 20, aa 35, ml 20, epim 30, pa 35. Tergite IX setae: S1 60, iS 35, S2 60. Tube length 100. Antennal segments III–VIII length 50, 50, 50, 45, 40, 20.
Male aptera: Similar to female in colour and structure except, postocular setae finely pointed, fore tarsal tooth about half as long as tarsal width; sternite VIII with small, sub-circular pore plate medially ( Fig. 67 View FIGURES 63–72 ).
Measurements (paratype male in microns). Body length 1300. Tergite IX setae: S1 35, iS 30, S2 20.
Material studied. Holotype female aptera, Australian Capital Territory, Namadgi , from dead twigs with lichen, 27.xii.2005 ( LAM 4784 ).
Paratypes: Australian Capital Territory, 2 male apterae taken with holotype; Tasmania, Buckland, Pulchella garden, 1 male aptera from dead branch, 27.xi.2010 ; Queensland, Cairns, Barron Gorge , 1 male aptera from dead branch, 6.xi.2008 .
Comments. This species differs from most of the others in this genus in the shorter head, broader pedicel on antennal segment VII, and the small, sub-circular male pore plate ( Fig. 67 View FIGURES 63–72 ). The range over which these few specimens have been taken, from Tasmania to Cairns, is remarkable, and suggests that this species is wind dispersed despite being apterous.
