Description. Male c. 14 mm long, H = 1.3 mm. In alcohol, under low magnification with uniformly very pale brown body colour. Antenna short ( Fig. 69 View Figure 69 mil). Paranota reduced, R = 1.4, anterior shoulders squared rather than rounded ( Fig. 70 View Figure 70 mil), posterior corners slightly turned up. Legs moderately robust, tarsus shorter than femur, tibia with slight ventral distal swelling, sphaerotrichomes on tibia and tarsus only of leg 6 ( Fig. 71 View Figure 71 mil). Telopodite ( Fig. 51 View Figure 51 ) reaching leg 5 when retracted. Solenomere arising at half the telopodite height, directed posterobasally at large angle to telopodite axis but bending at about one-third the process length distally and slightly mesally, terminating with small subapical projection at between one-third and half the prefemoral process height. Tibiotarsus origin on posteromesal surface of telopodite, not close to solenomere origin; tibiotarsus a posterobasally flattened triangular plate with a bluntly pointed tip, directed at c. 45° to telopodite axis, about one-third the solenomere length. Femoral process arising at level of solenomere origin, directed distally and pressed close to prefemoral process, blade-like with a slight anterior shoulder distally, tip rounded, terminating at one-third to half the prefemoral process height (at level of solenomere tip). Prefemoral process somewhat narrower than telopodite base, tapering, the distal one-third curving posterobasally and slightly mesally and bearing a comb of c. 15–20 long, mainly basally directed teeth; a cluster of three small tooth-like projections on mesal edge of prefemoral process at about two-thirds the process height. Uncus prominent, arising at level of solenomere and femoral process tips towards lateral edge of prefemoral process.

Distribution and habitat. Known from three localities in cool temperate rainforest in the Yarra Ranges east of Melbourne ( Fig. 78 View Figure 78 ).

Etymology. Named for Graham Milledge, who collected this and many other interesting invertebrate species in the mid-1990s from Nothofagus forest in Victoria.
