Silhouettanus magnus sp. n.

( Figs 7 , 8 , 18 B, 18D, dimensions in Table 1 .)

Type material. Holotype: T189829, mac. ♂, SEQ,], 26º54´S 151º38´E, Bunya Mountains near Munros Camp, 24 Oct 1997, G. Thompson, QM sample 5027, pyrethrum knockdown on hoop pine [ Araucaria cunninghamii ] trunks, left fore wing and genitalia on two slides, remainder in vial, in QM. Paratypes: T189830-2, 1 mac. ♂ and two mac. ♀, as for holotype, in vial and 1 slide, in QM.

Description. Male macropterous, brown, without pale bands on wings. L4 long, ratio of lengths of labial segments 22:13:7:45. Costal lobe wide, with little taper distally; R+M diverges from Sc basally so that costal lobe is elongate; cell R <discal cell, divergence of M from R is distal to basal cell, less than half area of cell R is distal to apex of discal cell; 1AN joins Cu opposite tornus; vein setae long (twice vein width). T8 not produced at either end; left anophoric process straight, spatulate, weakly tapering in distal half, projecting posteriorly almost to margin of genital capsule; right anophoric process is elongate strut embracing genital capsule laterally; left paramere with bulbous base and short, slender, tapering distal lobe; right paramere with bulbous base bearing apically bilobate arm; one conjunctival sclerite bearing large spatulate process with serrate margin; second conjunctival sclerite bearing short, curved spine; vesica has one sclerotized coil. Female macropterous ( Figs 8A–B ).

Notes. This is the largest species described here and from the most southerly locality which is remnant Araucaria forest.

Etymology. Latin for large reflecting that this is the largest species known; adjective.
