Hoplothrips oakeyi View in CoL sp. n.

( Figs 14, 15 View FIGURES 10–20 , 37 View FIGURES 31–45 , 51 View FIGURES 46–52 , 60 View FIGURES 53–66 )

Female macroptera. Body, legs and antennae light brown, fore tibia lighter, all tarsi yellow; antennal segment III with base yellow ( Fig. 37 View FIGURES 31–45 ). Head with genae convex, weakly sculptured posterolaterally; dorsal length of compound eyes about half of head length; postocular setae pointed, shorter than dorsal eye length; maxillary stylets retracted to postocular setae, close together medially ( Fig. 14 View FIGURES 10–20 ). Antennal segment III with 3 long sense cones, IV with 4 long sense cones, IV–VII with distinct pedicels, VIII broadly connected to VII ( Fig. 37 View FIGURES 31–45 ). Pronotum without sculpture; major setae minute to small, pa setae often slightly longer than epim, apices varying from pointed to blunt ( Fig. 14 View FIGURES 10–20 ). Mesonotum with weak transverse sculpture on anterior half, lateral setae minute; metanotum with no sculpture medially, median setae small and pointed ( Fig. 51 View FIGURES 46–52 ). Prosternal basantra absent, mesopresternum boat-shaped but slender medially, mesoeusternal anterior margin entire. Fore tarsal tooth sharply pointed, length about half of tarsal width. Fore wing sub-basal setae small, 8–11 duplicated cilia. Pelta with small lobes ( Fig. 51 View FIGURES 46–52 ); tergites II–VII each with a pair of sigmoid wing-retaining setae, weaker on II and VII, anterior pair on each tergite small and curved; tergite VIII median setae pointed; tergite IX setae S1 pointed, shorter than tube; anal setae longer than tube.

Measurements (holotype female in microns). Body length 2220. Head, length 202; width 225; postocular setae 50, distance between their bases 188; postocellar setae 12, distance between their bases 57. Pronotum, length 150; median width 258; major setae am 12, aa 24, ml 15, epim 41, pa 41. Mesonotum lateral setae 10; Metanotum median setae 26. Tergite IV median marginal setae 65; tergite VIII median setae 57, tergite IX setae S1 93, S2 91. Tube length 140. Anal setae 203. Antennal segments III–VIII length (width) 75 (36), 74 (38), 63 (33), 46 (28), 39 (23), 26 (17). Fore wing length 85, sub-basal setae S1 27, S2 27, S3 20.

Female microptera. Similar to macropterous female, compound eyes and ocelli smaller; mesopresternum slen- der boat-shaped; tergal wing-retaining seta weaker.

Measurements (in microns). Body length 2660. Head, length 200; width 203; postocular setae 38; fore wing lobe 100.

Male microptera. Similar to apterous female but smaller ( Fig. 15 View FIGURES 10–20 ); fore tarsal tooth stouter; tergite IX S2 setae short; sternite VIII with small indistinct circular pore plate ( Fig. 60 View FIGURES 53–66 ), sternites IV-VII with small areas of specialised reticulation laterally.

Measurements (in microns). Body length 1970. Head, length 197; width 173; postocular setae 51. Pronotum, length 145; median width 207; major setae am 12, aa 20, ml 16, epim 30, pa 37. Tergite IX setae S1 75, S2 48. Tube length 108, anal setae 187. Antennal segments III–VIII length 65, 63, 53, 43, 38, 28.

Specimens studied. Holotype female macroptera. Australian Capital Territory, Oakey Hill , from Eucalyptus blakeleyi dead branches, 6.iii.2011 ( LAM 5445 ) in ANIC.

Paratypes: 3 females micropterae, 2 males, same data as holotype; Black Mountain , 1 male from dead wood, 19.ix.2011. Queensland, Brisbane F. P ., 1 female microptera, 1 male from dead branch with moss, 16.i.2006; Mt. Coot-tha , Fire trial , 1 female microptera from dead wood, 1.xi.2007. Broadwater Lake, 10km west of Dalby , 1 female macroptera from Casuarina cristata , 19.x.1985. Carnarvon Station , 1 female macroptera from dead wood, 8.x.2014.

Comments. This species is probably related to the H. fungi complex but has antennal segment VII short and broadly joined to VIII, and the pronotal epim setae unusually short. Sternite VIII of the males is unusual in having a pore plate that is only faintly indicated in some individuals ( Fig. 60 View FIGURES 53–66 ).
