Hoplandrothrips gloriosi sp.n.

( Figs 11, 14 )

Male macroptera. Body, legs and antennae brown, except antennal segment III clear yellow, tarsi yellow, hind tibiae bicoloured yellow at base and apex but brown medially.

Head with cheeks weakly convex, head with weak reticulation medially but stronger laterally; median dorsal area with no sculpture; ventrally with only one pair of long setae; postocular setae far apart, capitate, shorter than eye width; eyes much longer dorsally than ventrally; maxillary stylets retracted to compound eyes, close together medially ( Fig. 11 ); mouth cone short and rounded. Antennae 8-segmented; sensoria slender, III with 3 sensoria, IV with 4 sensoria; VIII narrowed to pedicellate base.

Pronotum sculptured, with swirling lines anterolaterally ( Fig. 11 ); all 5 pairs of setae capitate; basantra absent, chitinous islets small; mesopresternum of two lateral triangles. Fore legs slender, without tubercles; fore tarsal tooth very small. Mesonotum transversely reticulate, lateral setae small, capitate. Metanotum striate medially ( Fig. 14 ); median setae acute, arising on anterior third of sclerite. Fore wings parallel sided, sub-basal setae capitate.

Pelta almost rectangular with base flared; tergites II–VII with 2 pairs of wing retaining setae; laterally with reticulate sculpture bearing small teeth; tergal lateral setae capitate, S1 with apex asymmetric on II–V; tergite IX setae S1 and S2 weakly capitate, intermediate seta as long as S2. Sternites III–VII with few discal setae, no specialised reticulation; sternite VIII with broadly transverse pore plate medially.

Measurements (holotype male in microns). Body length 1500. Head, length 225; width across cheeks 150; postocular setae 30. Pronotum, length 100; width 200; major setae—am 15, aa 15, ml 15, epim 38, pa 38. Fore wing, length 600; sub-basal setae 25, 25, 25. Tergite IX setae, S1 35; S2 50; S3 115. Tube length 120. Antennal segments III–VIII length 55, 55, 50, 45, 35, 30.

Female macroptera. Colour and structure similar to male; head with sculpture stronger; mesopresternum transverse but slender; fore tarsus without tooth; fore wing slightly narrowed medially, with 6 duplicated cilia; tergite IX setae S1 and S2 weakly capitate, intermediate seta about half as long as S2.

Measurements (paratype female in microns). Body length 1850. Head, length 250; postocular setae 30. Pronotum, length 150; width 230; Fore wing, length 750. Tergite IX setae, S1 65; S2 65; S3 80. Tube length 150.

Specimens examined. Holotype male. Queensland, Brisbane, Mt Glorious, from dead leaves and branches, 10.v.2007 (DJ Tree 464).

Paratype female, same locality, from dead branch, 9.iii.2006.

Comments. The metanotal sculpture of this species is similar to that of bartlei , but the antennal sensoria are long and slender, the mouth cone short and rounded, and the pronotum has distinctive sculpture.
