Croft, Site 17C, Trap 9. <b>Diagnosis</b>. Separated from all species except <i>B. dorrigo</i> by the thick, flattened embolic tip. Distal conductor more expanded and angular, and embolus shorter than in <i>B. dorrigo</i>. Epigynal fossa trapezium-shaped, lateral margins usually concave. <b>Male</b> (holotype). BL 7.04, CL 3.24 (2.65–3.24), CW 2.25, CapW 1.31, EGW 0.99, LL 0.47, LW 0.47, SL 1.50, SW 1.39. Legs: 1243 (I: 18.53; II: 15.13; III: 11.85; IV: 15.00); ratio tibia I length:CW = 1:0.45. Male Palp: (Fig. 5a,b). Patella only slightly longer than wide. RTA robust, tapering from broad base. Conductor a thick, sclerotized stalk, strongly expanded distally (angular, box-like) and extending retrolaterally and ventrally beyond the end of the wide embolic groove and embolus apex. Embolus a relatively short, thick, curved rod, distal part flattened and curving ventrally in the embolic groove. Tegular window smaller than in <i>B. dorrigo</i>. <b>Female</b> (KS57382). BL 5.76, CL 2.73 (2.20–2.73), CW 1.88, CapW 1.27, EGW 0.92, LL 0.41, LW 0.41, SL 1.33, SW 1.14. Legs: 1423 (I: 10.86; II: 8.78; III: 7.47; IV: 9.18); ratio tibia I length:CW = 1:0.69. Epigynum: (KS57682; Fig. 5c,d). Shallow, trapezium-shaped fossa, narrowestanteriorly; lateral margins usually weakly concave, rather than straight. Internal genitalia:(KS57682; Fig. 5e). Copulatoryducts broad, lateral margins weakly concave proximally, then convex. Spermathecae in broad contact medially. <b>Distribution</b>. Clarence River catchment from the northern Richmond Range to the Washpool State Forest region, NE New South Wales. Nov 1969, M. R. Gray, damp forest. PARATYPE &amp;female; KS77192, data as holotype. <b>Diagnosis</b>. Male palpal patella clearly longer than in other species (Fig. 6b [cf. Fig. 7b]). Epigynal fossa ovoid. <b>Male</b> (holotype). BL 5.02, CL 2.45, CW 1.84, CapW 1.02, EGW 0.75, LL 0.35, LW 0.35, SL 1.16, SW 1.14. Legs: 1423 (I: 10.94; II: 9.18; III: 7.92; IV: 9.47); ratio tibia I length:CW = 1:0.69. Legs somewhat shorter than in other species. Male Palp: (Fig. 6a,b). Femur and patella relatively elongate, patella about 2.5× longer than wide; tibia robust. RTA large and very thick basally. Cymbium apical area relatively shorter and with fewer bristles (0–1); cymbial flange of moderate size. Conductor T-shaped; “head of T” short and wide, the retrolateral end shallowlybifurcate with the broad embolic groove ending upon the upper, sclerotized, beak-like process. Embolus thick basally, gradually tapering until flattening distally into a wide, translucent flange with a thicker dorsal edge and pointed apex. Tegular window small. <b>Female</b> (KS77192). BL 6.04, CL 2.37, CW 1.67, CapW 1.10, EGW 0.73, LL 0.33, LW 0.37, SL 1.12, SW 1.06. Legs: 1423 (I: 8.49; II: 7.02; III: 6.04; IV: 7.31); ratio tibia I length:CW = 1:0.82. Legs somewhat shorter than in other species. Epigynum: (KS77192; Fig. 6c). Strongly straight and relatively narrow. Spermathecae adjacent, slightly separated medially. <b>Distribution</b>. Known only from the type locality on the edge of the New England escarpment.
