Diagnosis. The epigyne of B. cooki resembles that of B. ensigera and B. hakani by having a narrow and crescent-shaped epigynal hood, but differs by the relative size of the vertical part of the copulatory ducts as compared to the total epigynal plate, which is about 2/3 ( Figs 6 , 8 ) (vs. 1/ 3 in the other two species, Panayiotou et al. 2010: figs 12, 23). Males of B. cooki are also very similar to those species in their genital structures (long embolus and conductor conformation), but can be distinguished by the presence of a patellar apophysis ( Fig. 5C ) (absent in the other two species) and the very short retrolateral tibial apophysis, ca 1/10 of the cymbium length ( Fig. 5C ) (1/2 of the cymbium or longer) (compare Fig. 7C with Panayiotou et al. 2010: figs 10, 16.).

Carapace reddish brown with distinct fovea, abdomen with triangular small scutum, oval, covered with yellowish-grey pubescence. Legs uniformly brown. Chelicerae, sternum, labium and maxillae brown. Cheliceral promargin with 4 and retromargin with 2 teeth. Eyes in two rows, anterior row slightly recurved, posterior row procurved with posterior median eyes oblique.

Palpal patella with a small apophysis. Retrolateral tibial apophysis short, horn-shaped with slightly curved tip ( Fig. 5C ). Cymbium with retrolateral extension. Conductor with: broad membranous anterior bladder (a) ( Fig. 5B ), sickle-shaped guiding structure (b) beginning at the 12 o’clock position of the tegulum and extending retrolaterally in a wide C-shape curl to reach the 6 o’clock position with a posterior hook (c) ( Fig. 5A–C ). Embolus long, filiform, originating at about 6:00 o’clock and making a full circle ( Fig. 5A–C ).

Description. Female ( Fig. 4C, D ). Measurements: TL: 8.0, PL: 3.5, PW: 2.5, OL: 4.5, OW: 2.5, Eye sizes and inter-distances: AME 0.0875, ALE 0.125, PME 0.1375, PLE 0.0875, AME–AME 0.0875, AME–ALE 0.025, AME–PME 0.15, PME–PME 0.05, PME–PLE 0.0875, PLE–ALE 0.0875. Lengths of leg segments: I: 8.875 (2.25, 1.5, 2.125, 1.75, 1.25); II: 7.5 (2.125, 1.25, 1.625, 1.5, 1.0); III: 6.625 (1.75, 0.875, 1.5, 1.625, 0.875); IV: 11.125 (2.25, 1.5, 2.125, 2.75, 1.25).
