Holoengythrips tallagandai View in CoL sp.n.

( Figs 39 View FIGURES 34–42 , 58, 59 View FIGURES 55–62 , 69 View FIGURES 63–72 )

Female macroptera: Body and legs brown, mid and hind femora paler distally, tarsi yellowish brown; antennal segment I and base of III yellowish brown, II light brown, remaining segments brown, major setae shaded. Head much longer than wide ( Fig. 39 View FIGURES 34–42 ), dorsal surface almost without sculpture, ocelli well-developed, cheek setae weak, postocular setae pointed and shorter than eye length; mouth cone not extending to ferna. Antennal segment III with 2 sensoria, IV with 4 sensoria; IV–VII with parallel-sided pedicel, VIII slightly constricted at base. Pronotum transverse, with no sculpture, 5 pairs of pointed major setae. Fore tarsal tooth pointed, less than half as long as tarsal width. Mesonotal lateral setae longer than posterior pairs; metanotum with one pair of small major setae, without sculpture medially. Fore wing parallel-sided, with 6 or 7 duplicated cilia; sub-basal setae short, variable in length and number. Prosternal ferna scarcely meeting medially; mesopresternum of two slender sclerites, mesoeusternal margin weakly angulate ( Fig. 59 View FIGURES 55–62 ); metathoracic sternopleural sutures present. Pelta anterior margin rounded; tergites with almost no sculpture, II–VII with two pairs of wing-retaining setae; major setae on II–VIII pointed; tergite IX setae S1 and S2 pointed. Anal setae shorter than tube. Sternites with one row of about 10 small discal setae.

Measurements ( holotype female in microns). Body length 2000. Head, length 275; median width 175; postocular setae 60. Pronotum, length 110; median width 250; major setae: am 25, aa 25, ml 25, epim 55, pa 40. Tergite IX setae: S1 100, iS 35, S2 110. Tube length 130. Antennal segments III–VIII length 60, 55, 55, 52, 48, 30.

Female microptera: similar to macroptera but wing-retaining setae short and straight.

Male microptera: Similar to female in colour and structure except, fore tarsal tooth longer than tarsal width, fore femora slightly swollen, fore coxae with several short stout setae; mesothoracic spiracular area prominent; mesoeusternal margin sharply angulate ( Fig. 58 View FIGURES 55–62 ), mesopresternum of two strongly divergent triangles; sternite VIII with pore plate occupying anterior two-thirds of sclerite ( Fig. 69 View FIGURES 63–72 ).

Measurements ( paratype male in microns). Body length 2500. Tergite IX setae: S1 100, iS 35, S2 50.

Material studied. Holotype female macroptera, New South Wales, Tallaganda, Lowden Forest Park, from dead Eucalyptus , 9.ii.2013 ( LAM 5736 ).

Paratypes: 3 female macropterae taken with holotype. Australian Capital Territory, Black Mt. , from dead branch , 1 male microptera, 28.viii.1995, 1 male microptera, 26.ii.2011. Victoria, Nelson , 1 male microptera from Acacia dead twigs, 13.iii.2011. Queensland, Lamington , O’Reillys , 1 male from dead leaves, 11.x.2006.

Comments. This species is very similar in body structure to maynardae , but it is uniformly dark brown, has only two sensoria on the third antennal segment, and the male lacks a tubercle at the apex of the fore tibia.
