Hoplothrips corticis (De Geer)

( Figs 3 , 32 , 47 , 57 )

Thrips corticis De Geer, 1773: 11 . Female macroptera. Body and femora brown; tibiae yellow shaded brown, tarsi yellow; antennal segment III mainly yellow, IV–VI variably yellow at base but not sharply bicoloured; fore wings weakly shaded toward apex. Head longer than wide, genae with several small, slender setae; postocular setae very long and pointed, wide apart; maxillary stylets retracted to eyes, close together medially ( Fig. 3 ). Antennal segment III with 3 short, straight sense cones, IV with 4 sense cones ( Fig. 32 ); VIII constricted to base. Pronotum without sculpture medially, with 4 pairs of very long, slender pointed major setae, am scarcely larger than discal setae ( Fig. 3 ); prosternal basantra absent. Fore tarsal tooth large. Metanotum without sculpture medially ( Fig. 47 ). Fore wing with about 10 duplicated cilia. Pelta with lateral margins confluent with anterior margin of tergite II ( Fig. 47 ); tergites II–VII with two pairs of sigmoid wing-retaining setae; tergite IX setae S1 pointed, at least 0.8 as long as tube.

Female microptera. Wings shorter than thorax width; antennal segment III sometimes with 2 sense cones; genae swollen behind small forwardly directed eyes. Male microptera. Large males with fore femora swollen; tergite IX setae S2 short and stout; sternite VIII with large pore plate that scarcely extends posterior to spiracles ( Fig. 57 ), median longitudinal length of pore plate 50–60 microns.

Specimens studied. Queensland, Bunya Mts, 9.iv.1993, 2 female micropterae from Araucaria bidwilli litter; Norfolk Island, Selwyn Pine Road , 6 female macropterae, 3 female micropterae, 1 male microptera, from dead branches, 26.xii.2012 .

Comments. Described from Europe where it is widespread ( Mound et al. 2018), this species is known also from eastern North America and New Zealand ( Mound & Walker 1986). In Australia, it has been reported from Norfolk Island ( Mound & Wells 2015) and is here recorded from southeastern Queensland.
