Mound, Laurence A. & Tree, Desley J., 2013, Fungus-feeding thrips from Australia in the worldwide genus Hoplandrothrips (Thysanoptera, Phlaeothripinae), Zootaxa 3700 (3), pp. 476-494 : 480

Hoplandrothrips bartlei sp.n.

( Figs 2, 5 )

Female macroptera. Body, legs and antennae brown, tarsi and apices of tibiae paler, antennal segment III paler in basal third, also pedicel of IV; epimeral setae pale, but 4 pairs of capitate pronotal setae dark, also postocular and median metanotal setae; fore wings weakly shaded.

Head weakly reticulate dorsally, ventrally with 3 pairs of long setae; maxillary stylets retracted to eyes, close together medially ( Fig. 2 ); postocular setae short and capitate, arising behind inner margin of eyes; mouth cone pointed, extending to mesosternum. Antennae 8-segmented; III with 3 sensoria, IV with 4 sensoria; VII with pedicel, VIII broadly pedicellate but narrower than apex of VII.

Pronotum with no sculpture except near posterior margin; major setae with fringed capitate apices, epimeral setae with apices greatly asymmetric; basantra absent; mesopresternum broadly boat-shaped. Fore legs slender, fore tarsus with small tooth on inner margin. Mesonotal sculpture lines weakly dentate, lateral setae small, capitate. Metanotum strongly striate ( Fig. 5 ), median setae capitate and arising on anterior half of sclerite. Fore wings slender, sub-basal setae capitate; with about 6 duplicated cilia.

Pelta elongate bell-shaped; tergites II–VII with 2 pairs of wing retaining setae, each anterior pair weaker than each posterior pair; tergites laterally with dentate sculpture; lateral setae S1 on II–VI with asymmetric, fringed apex; and S2 capitate; tergite IX setae S1 and S2 weakly capitate, intermediate seta not elongate.

Measurements (holotype female in microns). Body length 1900. Head, dorsal length 230; ventral length to mouth cone apex 450; width across cheeks 175; postocular setae 40. Pronotum, length 110; width 230; major setae—am 20, aa 25, ml 20, epim 60, pa 25. Fore wing, length 650; sub-basal setae 20, 20, 50. Tergite IX setae, S1 55; S2 65; S3 100. Tube length 150. Antennal segments III–VIII length 65, 60, 50, 50, 45, 25.

Specimens examined. Holotype female, Queensland, Mt Bartle Frere, pyrethrum fogging of logs, 19.xi.2009 (G. Monteith & F. Turco).

Comments. Known from only a single female, this species is distinctive within the genus in the striate form of the metanotal sculpture and the broadly capitate and fringed, but dark, major setae. The rather elongate head is similar to North American species placed in Phloeobiothrips , although that is now considered a synonym of Hoplandrothrips .
