Silhouettanus monteithi sp. n.

( Fig. 9 , dimensions in Table 1 )

Type material. Holotype: T189833, mac. ♂, SEQ, 26º08´S 151º18´E, Nangur State Forest, 320m, 24 Nov 1995, G. Monteith, pyrethrum knockdown on trees, dissected on seven slides, in QM.

Description. Brown, without pale bands on wings. L4 long, ratio of lengths of labial segments roughly 2:2:1:4. Costal lobe wide, R+M diverging from Sc basally so that subcostal cell 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 medium. T8 projecting a little on right but not forming a strut to embrace genital capsule; left anophoric process possibly straight, spatulate; right anophoric process a long, curved strut embracing genital capsule; left paramere a long curved arm with blunt bilobate apex; right paramere probably like a bent arm; first conjunctival sclerite possibly with small spatulate process; second conjunctival sclerite with short, curved spine; vesica elongate, with sclerotoized basal flange (helicoid sclerite?) and several (about six), slender loops.

Notes. S. lintrarius is very similar to this species, sharing a long many-coiled vesica; the left paramere is longer and the right anophoric appendage is present and long in S. monteithi .

Etymology. In recognition of the work by Dr G. B. Monteith and his colleagues at Queensland Museum in surveying not only the major rainforests of Queensland but also numerous less iconic habitats such as Nangur State Forest that sustain Schizopteridae .
