Scirtothrips longipennis (Bagnall)

[ Fig. 14 ]

Euthrips longipennis Bagnall, 1909: 173 ­174.

Described from specimens taken in a greenhouse in Brussels, this species was at one time reported to be a widespread minor pest under glass, apparently associated with begonia plants. Despite this, very few specimens are available in museum collections, and only two females have been seen from Australia. The descriptive notes and illustrations given here are from one of these, a female taken recently on Lord Howe Island. The male is unknown.

Female macroptera. Colour: Yellow, anterior margin of head light brown; antecostal ridges dark on tergites III­VIII and on sternites V­VII; forewings strongly shaded in basal half but paler toward apex; antennal segment I pale, III – VIII dark.

Structure: Vertex with transversely anastomosing striae, ocellar region transversely striate; ocellar setae pair III further apart than their length, rising near margins of ocellar triangle; two pairs of post­ocular setae longer than ocellar setae III. Pronotum with transverse striae wavy and widely separated; 2 anteromarginal setae, 8 discal setae; 4 pairs of posteromarginal setae, S2 slightly longer than width of antennal segment II. Metanotum weakly longitudinally reticulate, median setae close to margin. Forewing scale with 3 marginal setae; first vein setae 3+2+1+1+1; second vein 2 setae; posteromarginal fringe cilia undulating except near apex. Tergite I without discal setae, III­V median setae longer than distance between bases; tergal microtrichial fields with 3 discal setae; VIII with no discal microtrichia medially, posteromarginal comb complete; tergite IX with discal microtrichia on posterior half. Sternites with microtrichial fields extending almost to S2.
