Other Material. South Australia: 1♂, Naracoorte Caves Reserve, 37°02'S, 140°48'E, 18 Feb 1995, A. Baynes, WAM 95 /410.
Diagnosis. Males are similar to those of B. bidgemia sp. nov. and B. microspinosus sp. nov. in the structure of the embolic flange (Fig. 32b); the rugose coxa I (Fig. 31a, e) of both males and females readily distinguish it from other species.
Etymology. The species epithet refers to the rugose surface of coxa I.
Description holotype male WAM 98/1639
Carapace 4.48 long, 3.04 wide. Abdomen 4.96 long, 2.32 wide. Total length 9.5.
Colour: carapace dark red brown, strial edges darker; abdomen dorsally brown with two large white spots in anterior third, a much smaller pair behind that and inverted U-shaped band in front of spinnerets; laterally a small pallid triangular area near booklungs and larger comma-shaped mark mid-laterally; dorsal scute narrow, almost for half length; abdomen ventrally centrally a pallid quadrangle. Chelicerae, fangs, sternum, maxillae and labium red brown; coxae and legs yellowish (I and II) to pallid (III and IV). Femora bicolored, basally half orange, distally dark brown; otherwise legs yellow to orange brown. Carapace: with uniform cover of fine hair; fovea short, deep. Posterior slope gradual from anterior third. Chilum entire but deeply incised ventrally. Chelicerae: large; anterior process a rounded flange, hair horizontal, slender. Fangs moderately long, diagonal. Furrow long; promargin with one large and one smaller tooth; retromargin with two similar medium-sized teeth, all teeth set well back from fang base. Maxillae: rhomboidal with long groove along ental edge; sternum broadly cordate but narrowing moderately strongly from coxae I; almost flat, indented behind labium. Legs: lightly hirsute. Spines: ventrally on tibiae I and II, three pairs of long, strong, attenuate spines on raised bases, plus shorter distal pair. I: fe pv1 long p2d3; ti p2r2v2.2.2.2; me v2.2. II: fe pv1p2d3; ti p2r1v2.2.2.2; me p2r2v2.2. III: fe p3d3r3; ti p2r2v2.2.1; me p3r3v2.2.3. IV: fe p2d3r1; pa0; ti p2r2v2.2.2; me p3r4v2.2.3. Palp: fe p1d2v0; pa p1; ti p2d1. Scopula: weak but distinct for length of tarsi I–III; divided in distal half of metatarsi I and II. Claws: similar sized tufts and length on all legs, tufts project forward and above claws. Palp: tibia with prolateral glabrous saddle; cymbium fusilliform with small nubbin-like paracymbial spine; narrow scopula dorsally for distal half; bulb pyriform with very shallow pro- and retrolateral parategular indentations; spermatic duct medial and very close to secondary loop; pre-embolic ridge short, low; distal flange flat, wide, short, not behind short spike-like embolus; two apices evident from below. Abdominal scutes: dorsal, narrow ovoid with smooth margin, almost to midlength and not extending to flank, genital scute not enclosing pedicel, lightly sclerotised over genital region and booklungs, no post-epigastric sclerites; tracheal slightly raised ridge wide, weakly sclerotised. Spinnerets: ALS wider than PLS but of similar length.
Allotype Female. As for ♂ except:
Carapace 4.40 long, 2.96 wide. Abdomen 5.76 long, 3.52 wide. Total length 10.2.
Colour: carapace lighter; abdomen (contracted away from cuticle) dorsally fawn brown with spots as ♂; lateral triangles much larger; regenerated femur I orange brown, not bicoloured. Ovoid PME. Chelicerae: stout vertical, with pronounced fang shield with 10–15 long curved black setae; fang shorter than in ♂; dentition 2R, 2P. Sternum with separated weak pre-coxal sclerites on III and IV. Legs: trochanters with very shallow notches. Spines: on tibiae (I) II, as in ♂. I: regenerated. II: fe pv1p2d3; ti p2v2.2.2.2; me p2v2.2. III: fe p2d3r2; ti p1r2v2.2.1; me p3r3v2.2.3. IV: fe p2d3r1; ti r2v2.2.2; me p3r3v2.2.3. Palp: fe p1d2; pa p1d1 apical; ti p2 (basal) d1; ta p1. Palp: tarsus long, distinctly subdistally incrassate, with slender finely dentate claw with cluster of short thick setae and hairs predistally on dorsal mound. Abdomen: with small triangular scute dorsally just over anterior shoulder ca. for 1/8th length, genital scute not as sclerotised as epigyne edges; tracheal scute ridge short, low, in small ovoid area. Epigyne: with two relatively large ovoid fossae laterally.
Distribution. Known only from south-western Western Australia and the Baird Bay area, South Australia.
