Haplothrips driesseni sp. nov.

Female macroptera. Body colour brown to dark brown, tarsi and base of antennal segment III yellowish brown; fore wing shaded medially. Head longer than wide ( Figure 45 ); maxillary stylets less than one-fifth of head width apart, retracted anterior to postocular setae, maxillary bridge complete; postocular setae capitate, extending to posterior margin of compound eyes. Antennal segment III with two slender sensoria, IV with four sensoria. Pronotal am setae no larger than discal setae, four pairs of major setae capitate but aa and ml small. Mesonotal lateral setae capitate. Metanotum without sculpture medially, median setae arise medially on sclerite. Mesopresternum transverse. Fore tarsal tooth small, at inner apex of tarsus. Fore wing with no duplicated cilia, sub-basal setae capitate. Tergites II–III with neither sculpture nor discal setae lateral to wing-retaining setae ( Figure 38 ); posteromarginal setae S1 long and capitate on tergites II–VII; tergite IX S1 capitate, S2 weakly capitate.

Measurements of holotype female (in M m). Body length 1950. Head, length 200; median width 160; postocular setae 35. Pronotum, length 120; width 210; major setae am 3, aa 15, ml 15, epim 50, pa 30. Fore wing length 750; sub-basal setae 20, 25, 40. Tergite IX setae S1 80, S2 70, S3 80. Tube length 125; basal width 55; anal setae 130. Antennal segments III–VIII length 50, 60, 60, 35, 35, 30.

Male macroptera. Similar to female in colour and structure; tergite IX setae S2 short and stout; apex of pseudovirga narrowly spoon-shaped.

Measurements of paratype female (in M m). Body length 1580. Head, length 185; median width 135; postocular setae 35. Pronotum length 115; width 200; major setae am 5, aa 15, ml 20, epim 35, pa 35. Fore wing length 620; sub-basal setae 20, 30, 35. Tergite IX setae S1 100, S2 40, S3 130. Tube length 120; basal width 50; anal setae 130. Antennal segments III–VIII length 50, 55, 53, 50, 48, 35.

Comments

The host plant of this species remains unknown, although it is likely to be a montane species of Juncaceae or Cyperaceae . The head is relatively long and the stylets relatively close together, and it is one of the few Haplothrips species with a distinctly shaded fore wing.
