Diagnosis. Separated from all species except B. yabbra   by the thick, flattened embolic tip. Embolus longer than in B. yabbra   and embolus and conductor groove reach almost to the end of the conductor (ventral view). Epigynal fossa trapezium-shaped, lateral margins usually straight.

Male (holotype). BL 4.73, CL 2.29 (2.29–3.31), CW 1.63, CapW 0.82, EGW 0.67 LL 0.35, LW 0.35, SL 1.14, SW 1.08. Legs: 1243 (I: 12.49; II: 10.16; III: 8.33; IV: 10.08); ratio tibia I length:CW = 1:0.51. (Male palp of KS77105 illustrated in Fig. 4a,b). Patella only slightly longer than wide. RTA robust, tapers rapidly from subapical region. Conductor a thick, sclerotized stalk, distally expanded with deep, wide groove supporting distal part of embolus. Embolus a thick, strongly curved rod, flattened distally, tip extending almost to end of conductor. Tegular window of moderate size.

Female (KS70125). BL 4.98, CL 2.33 (1.92–2.65), CW 1.55, CapW 1.02, EGW 0.75, LL 0.33, LW 0.35, SL 1.10, SW 1.06. Legs: 1423 (I: 9.43; II: 7.51; III: 6.29; IV: 7.63); ratio tibia I length:CW = 1:0.64. Epigynum: (KS70126: Fig. 4c). Shallow, trapezium-shaped fossa, narrowestanteriorly; lateral margins more or less straight, rather than concave. Internal genitalia: (KS70126: Fig. 4d). Copulatory ducts broad, lateral margins strongly convex. Spermathecae in broad contact medially.

Variation. Shape of epigynal fossa sometimes less symmetrical.

Distribution. Bellinger to Nymboidea River region, eastern slopes of Great Dividing Range, mid northeastern New South Wales.
