Hoplothrips lamingtoni sp. n.

( Figs 8 , 49 , 56 )

Female macroptera. Body, legs and antennae brown, tube darkest, tarsi paler; antennae brown, segments III–IV paler at base; major setae pale; fore wings weakly shaded. Head longer than wide, with transverse striate sculpture; genae sub-parallel, with a pair of stout setae on basal third; posterior ocelli close to compound eyes; dorsal length of compound eyes greater than one third of head length; postocular setae capitate, shorter than dorsal eye length; maxillary stylets retracted to postocular setae, close together medially ( Fig. 8 ). Antennal segment III with 3 sense cones, IV with 4 sense cones, III–VII each with pedicel, VIII slender but with base almost as broad as apex of VII. Pronotum with sculpture around margins; with 5 pairs of capitate major setae. Mesonotum with transverse polygonal sculpture, lateral setae capitate; metanotum reticulate, median setae long, pointed, on anterior third of sclerite ( Fig. 49 ). Prosternal basantra absent, ferna sharply pointed medially; mesopresternum eroded to three plates, mesoeusternal anterior margin entire. Fore tarsal tooth small, on basal half of tarsus. Fore wing with capitate sub-basal setae, 24–28 duplicated cilia. Pelta triangular ( Fig. 49 ); tergites with extensive sculpture, reticulate and transverse, segments II–VI each with two pairs of strongly sigmoid wing-retaining setae ( Fig. 56 ), VII with these setae weaker and wider apart; VIII median setae weakly capitate; IX setae S1 and S2 weakly capitate, shorter than tube; anal setae as long as tube.

Head, length 337; width 258; postocular setae 108, distance between their bases 205; postocellar setae 23, distance between their bases 47. Pronotum, length 187; median width 410; major setae am 43, aa 70, ml 75, epim 106, pa 68. Mesonotum lateral setae 53; Metanotum median setae 65. Tergite IV median marginal setae 175; tergite VIII median setae 115, tergite IX setae S1 178, S2 178. Tube length 220. Anal setae 221. Antennal segments III–VIII length (width) 100 (43), 93 (43), 88 (35), 75 (33), 65 (27), 45 (18). Fore wing length 122, sub-basal setae S1 63, S2 73, S3 108.

Specimens studied. Holotype female macroptera. Queensland, Lamington NP, O’Reilly’s, from Malaise Trap, i.2007, in ANIC.

Paratypes: 3 females with same data as holotype except x.2006 and xi.2007 ; 1 female, Bottom Creek , Mudlo NP, from rainforest barkspray, 21.xii.2011 .

Comments. This is an unusual species within the genus Hoplothrips . The transversely striate sculpture on the head is a character state more commonly associated with species of the Liothrips lineage.
