Silhouettanus turbator sp. n.

( Figs 14 , 18 C, dimensions in Table 1 )

Type material. Holotype: T189836, mac. ♂, NQ, Bellenden-Ker Range, 0.5km S cable tower 7, 500m, 17–24 Oct 1981, Earthwatch team of Queensland Museum, pyrethrum knockdown on logs, stones and trees, dissected on six slides, in QM.

Description. Brown with no pale bands on wings. L4 long, L3 very short, ratio labial lengths roughly 2:2:0.5–1:4. Eyes with two setae a little longer than facet-diameter. Costal vein not lobate but twice width of other veins and dorsally and ventrally carinate to form a strut, no incision of membrane at apex of costal strut; divergence of R+M from Sc basal so that subcostal cell is elongate; base of R+M ventrally carinate; cell R quadrangular, as large as discal cell; divergence of M from R is not distal to basal cell, only one fifth area of cell R is distal to apex of discal cell; junction of 1V and Cu distal to level of tornus; density of general papillae in hexagonal mosaic of wings is high, partially obliterating hexagonal pattern; enlarged papillae within pale circles around cell perimeters more conspicuous than in all preceding species. T8 probably not produced at either end; left anophoric process spinous, apically spiculate and sharply curved, projecting posteriorly half way towards margin of genital capsule; right anophoric process is strongly curved and spinous (rather than strut-like), embracing genital capsule laterally; left paramere with bulbous base and short broadly rounded, distal lobe; right paramere with bulbous base extending halfway and a tapering lobe distally; conjunctival processes not resolved; vesica has one sclerotized coil.

Notes. Several features of the venation set this species apart from others described here.

Etymology. Latin for disturber, alluding to the venation disturbing the generic definition; noun in apposition.
