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.
