Katothrips banksiae   sp. n.

(Figs 6–12)

Female aptera. Body and legs pale yellow, tube darker yellow; antennal segments I–II yellow, III sometimes weakly shaded, IV–VIII increasingly brown; major setae all translucent. Head longer than wide, weakly constricted behind eyes (Fig. 6); head without ocelli, with weak reticulation on lateral thirds, eyes slightly smaller ventrally than dorsally; 2 pairs of postocular setae, one pair placed laterally; maxillary stylets rather broad, retracted at least to postocular setae, close together medially but diverging posteriorly in the unusually broad mouth cone; maxillary guides stout; maxillary palps short, labial palps with prominent stout sense cone apically. Antennae 8-segmented (Fig. 12), III–V each with one short stout sense cone ventro-laterally. Pronotum without sculpture (Fig. 7), with 5 pairs of capitate major setae; notopleural sutures sometimes incomplete. Fore legs stout with tarsal tooth pointed and about as long as tarsal width. Prosternal basantra and mesopresternum absent, ferna weakly sclerotised, mesoeusternal anterior margin deeply eroded (Fig. 10). Mesonotum transverse, lateral setae capitate. Metanotum without sculpture or major setae (Fig. 8). Pelta transverse, weakly sculptured (Fig. 9); tergites II–VII with one pair of capitate setae posterolaterally, VIII–IX each with 2 pairs; tube shorter than head width, anal setae longer than tube. Sternites with 4–6 small discal setae, posteromarginal setae S1 unusually long, much longer than length of their sternite.

Measurements (holotype female in microns). Body length 1800. Head, length 185; maximum width 150; postocular setae 25. Pronotum, length 150; width 230; major setae, am 25, aa 30; ml 30, epim 33, pa 33. Tergite IX setae, S1 60; S2 55; S3 180. Tube length 100. Sternite VII posteromarginal setae S1 length 150. Antennal segments III–VIII length, 40, 38, 38, 38, 40, 23.

Female macroptera. Similar in colour and structure to aptera; head with ocelli present; metanotum with 2 to 6 small setae medially; tergites II–VII each with one pair of long, weakly sigmoid wing-retaining setae; fore wings parallel sided, without duplicated cilia, with two short capitate basal setae.

Male aptera. Similar in colour and structure to female aptera, slightly smaller; tergite IX setae S2 pointed and stout; sternite VIII with no pore plate.
