Material examined. Holotype. Male , Australia, Victoria. 3 km NW of Blackwood, 37°27'25'S 144°16'09''E, 560 m, 9.ix.2004, R. Mesibov & T. Moule, NMV K-8933.

Paratypes. 3 males, details as for holotype, AM KS91168 ; 10 males, details as for holotype, NMV K-8923 to K-8932 ; 13 females, details as for holotype, NMV K-8934 to K-8946 ; 13 males, 1 km NE of Blakeville , 37°29'45''S 144°13'07''E, 680 m, 10.ix.2004, R. Mesibov & T. Moule, NMV K-8947 to K-8959 GoogleMaps ; 8 females, same details, NMV K-8960 to K-8967 .

Description. Male c. 16 mm long, H = 1.4 mm. In alcohol, well-coloured specimens under low magnification with very pale brown body colour, red speckling dorsally on both prozonites and on metatergites, a well-defined transverse band of red speckling near posterior metatergal margins. Antenna moderately long ( Fig. 69 View Figure 69 bla). Paranota reduced but prominent, R = 1.4 ( Fig. 70 View Figure 70 bla); posterior corners not turned up, two inconspicuous posterior marginal teeth on each side. Legs robust, tarsus about as long as femur ( Fig. 71 View Figure 71 bla). Telopodite ( Figs 19 View Figure 19 , 20 View Figure 20 ) with sparse, long, setae extending posterolaterally to just distal of tibiotarsus origin, reaching leg 4 when retracted. Solenomere arising at one-third the telopodite height, directed posterodistally at about 45° to telopodite axis, gradually curving distally, terminating with very small subapical projection at one-quarter to one-third the prefemoral process height. Tibiotarsus more or less parallel to solenomere but shorter, about as wide as solenomere at base and widening distally, forking near tip and terminating in two blunt points. Femoral process arising proximal to solenomere origin, mesolaterally flattened and pressed close at base to prefemoral process, directed distally and widening before terminating in bluntly pointed apex just distal to solenomere tip, anterior to a slightly projecting “shoulder”. Prefemoral process very long, about half as wide as telopodite base, bending laterally just distal to solenomere tip, then bending mesally and curving anterodistally before flexing at nearly 180° to point basally, the lateral edge a comb of c. 40 long, mainly posteriorly directed teeth for nearly its entire length, a few small teeth on mesal edge close to apex. Uncus small, arising near base of prefemoral process on a ridge formed by the mesal edge of the process.

Distribution and habitat. Known from wet eucalypt forest at two localities 6 km apart in the southern portion of Wombat State Forest ( Fig. 78 View Figure 78 ).

Etymology. Named for Blackwood, the town closest to the type locality, 65 km north-west of Melbourne.
