Description. Male c. 18 mm long, H = 1.6 mm. In alcohol, well-coloured specimens under low magnification with pale brown body colour, red-purple speckling on metatergites and intense red-purple transverse banding along posterior margins of prozonites. Antenna with relatively large antennomere 6 ( Fig. 69 View Figure 69 gip). Paranota fairly wide with strongly produced anterior “shoulders” and two inconspicuous posterior marginal teeth, R = 1.5 ( Fig. 70 View Figure 70 gip), posterior corners not turned up. Legs robust, tarsus longer than femur, tibia with prominent ventral distal swelling ( Fig. 71 View Figure 71 gip). Telopodite ( Figs 36 View Figure 36 , 37 View Figure 37 ) almost reaching leg 4 when retracted. Solenomere arising at about half the telopodite height, directed distally with a slight posterior curvature, terminating with prominent subapical collar at about half the prefemoral process height. Tibiotarsus origin on posteromesal surface of telopodite, not close to solenomere origin; tibiotarsus a thin, pointed rod directed posterodistally at a small angle to telopodite axis, about one-quarter the length of the solenomere. Femoral process arising well proximal to solenomere origin, blade-like with a deeply notched tip, curved anteriorly and pressed close basally to prefemoral process, terminating at less than one-quarter the prefemoral process height (well proximal to solenomere tip). Prefemoral process about half as wide at origin as telopodite base, tapering slightly to mid-length but distally widening and flexing posteromesally, the tip pointed posteromesally, the lateral edge of the process a comb of c. 20 long, mainly posterobasally directed teeth from about two-thirds the process length. Uncus prominent, arising near base of prefemoral process on mesal side, with a widened, deeply notched tip.

Distribution and habitat. In wet eucalypt forest in West and South Gippsland ( Fig. 79 View Figure 79 ), often locally abundant. The Thorpdale specimens were collected in 1899, before the densely forested Thorpdale area was cleared for farming. The pre-European range of this species may have been as much as 1000 km 2, but is now possibly only a third of that figure.

Etymology. Named for the Gippsland district, the southern and western parts of which are home to this species.
