Diagnosis. The species can be distinguished from B. simoni , new species, by the lighter carapace (scarlet red vs. carmine red) and by the structure of the male and female copulatory organs: a terminal part of the tegular apophysis with a fairly developed bifurcation ( Figs. 3C, D View Fig , 4C, D View Fig ) vs. a shallow, almost indistinct depression in B. simoni , new species ( Fig. 4 View Fig G–I); the endogyne is ca. 3 times wider than long and the pore glands are located anteriorly ( Fig. 5A, B View Fig ), while in B. simoni , new species, the endogyne is about 1.5 times wider than long and the pore gland is located posteriorly.

Description. Male (from Bukit Frazer, ZMUT). Habitus as in Fig. 2A, B View Fig . Colour in alcohol: carapace, sternum, labium, chelicerae, maxillae, and dorsal abdominal scutum bright scarlet red; coxae and femora I–IV, and entire palp light orange; other segments of legs I–IV, and unsclerotised part of abdomen including spinnerets milky white.

Measurements: TL 2.36, CL 1.14, CW 0.87, CH 0.64, CyL 0.20, femur I L/W 3.44 (0.93/0.27). Carapace with moderately coarse granulations ( Fig. 3A View Fig ). Eye sizes and interdistances: AME 0.14, ALE 0.05, PLE 0.04, PME 0.05, AME–AME 0.04, AME–ALE 0.04, AME–PME 0.09, PLE–PME 0.11, PME–PME 0.14.

Palp and leg measurements: palp 0.99 (0.34 + 0.12 + 0.24 + 0.29), leg I 2.91 (0.93 + 0.64 + 0.60 + 0.31 + 0.43), leg II 2.51 (0.76 + 0.43 + 0.50 + 0.43 + 0.39), leg III 2.34 (0.67 + 0.39 + 0.46 + 0.46 + 0.36), leg IV 3.15 (0.94 + 0.43 + 0.71 + 0.64 + 0.43).

Palp ( Figs. 3C, D View Fig , 4 View Fig A–D, 5A–F). Tegular apophysis ( Ta) long (subequal to the length of tegulum), straight, with bent and bifurcated tip; embolus ( Em) well sclerotised, relatively long (ca. 1.5 times shorter than tegular apophysis), partly screwed (bent around the axis), with thin apophysis ( Ea).

Female (from Bukit Frazer, SMF). Habitus as in Fig. 2C, D View Fig . Colour in alcohol as in male.

Measurements: TL 2.65, CL 1.21, CW 0.91, CH 0.6, CyL 0.21, femur I L/W 2.97 (1.07/0.36). Carapace: longer, with less coarse granulations than in male ( Fig. 3E View Fig ). Eye sizes and interdistances: AME 0.11, ALE 0.06, PLE 0.04, PME 0.06, AME–AME 0.06, AME–ALE 0.06, AME–PME 0.06, PLE–PME 0.11, PME–PME 0.13.

Palp and leg measurements: palp 0.75 (0.24 + 0.09 + 0.21 + 0.21), leg I 3.20 (1.07 + 0.67 + 0.67 + 0.36 + 0.43), leg II 2.68 (0.86 + 0.43 + 0.57 + 0.43 + 0.39), leg III 2.39 (0.71 + 0.39 + 0.50 + 0.46 + 0.33), leg IV 3.47 (1.07 + 0.47 + 0.79 + 0.71 + 0.43).

Copulatory organ ( Fig. 6A, B View Fig ). Posterior edge of epigastric furrow (postgastric area) with a pair of lateral ( Ls) scuta, median scutum indistinct, lateral scuta almost invisible after maceration; endogyne almost three times wider than long; atrium ( At) large; lateral parts (receptacles?) suboval, well sclerotised, receptacles seem fused anteriorly; anterior part with pore-gland field ( Pg); grape-shaped glands very large, about 1/6 of endogyne width.

Note. Endogyne was lost during preparation of the figure.

Distribution. South part of the Malay Peninsula: Singapore and Malaysia ( Pahang State). See Fig. 8 View Fig .
