( Figs. 1 View FIGURE 1 C–F, L; 2G–H, P; 3C, G, K, N; 4A–B)
Type locality. Republic of South Africa: Western Cape, 24 km S of Clanwilliam, on rt. N7 (32°22'48.5''S, 18°56'41.4''E), 124 m, 7.x.2008, coll. P. Naskrecki & C. Bazelet - male holotype ( SAMC)
Diagnostic description (male, except where specified). General characteristics as for the genus, diagnostic characters listed below. B. wilsoni differs from other species within the genus in the unique shape of the male cercus ( Fig. 3 View FIGURE 3 G) and the female subgenital plate ( Fig. 2 View FIGURE 2 G.)
Thorax. Anterior margin of pronotum flat; broadly rounded; metazona flat, posterior edge of metazona slightly raised ( Fig. 1 View FIGURE 1 C), straight when seen from above ( Fig. 1 View FIGURE 1 E, F.)
Legs. Genicular lobes of front femur armed with two small spines on both sides. Mid femur unarmed ventrally, genicular lobes of mid femur armed with two small spines on both sides. Hind femur unarmed ventrally to armed with small spines on both ventral margins, genicular lobes of hind femur armed with single spines on both sides.
Wings. Stridulatory file flat, weakly bent, 6.5 mm long, 0.28 mm wide, with 55 teeth ( Fig. 1 View FIGURE 1 L.)
Abdomen. Tenth tergite unmodified. Cercus short, slightly bent inwards, distinctly thickened basaly ( Fig. 3 View FIGURE 3 G); straight when seen from side; apex tapered, with small apical tooth. Phallus entirely membranous, without sclerotized elements ( Fig. 3 View FIGURE 3 C.) Subgenital plate broadly trapezoidal, straight apically ( Fig. 2 View FIGURE 2 P); styli cylindrical, about twice as long as wide, parallel and separated by small gap, held horizontally. Female subgenital plate with short lateral lobes and small median incision, posterior lobes rounded ( Fig. 2 View FIGURE 2 G).
Ovipositor. Ovipositor slightly curved, shorter than half of hind femur, dorsal edge of upper valvula parallel to lower valvula ( Fig. 3 View FIGURE 3 K); apex pointed, with minute dentitions on both lower and upper valvulae ( Fig. 2 View FIGURE 2 H).
Egg. Egg elongate, cylindrical in crosssection, straight ( Fig. 3 View FIGURE 3 N).
Coloration. Coloration green, with variable markings ( Figs. 1 View FIGURE 1 E, F; 4A, B), antennae concolorous; antennal scapus without markings. Face pale green; eyes uniformly colored. Pronotum green, with darker markings dorsally, bordered by light stripes continuous with those on rest of thorax. Tegmen mostly dark brown, with costal area lighter than rest of wing. Legs with basal parts sometimes darker or lighter than distal parts; hind femur uniformly colored; abdominal sterna with median white stripe and pair of lateral, longitudinal white stripes; abdominal terga with oblique, white stripe on each lateral margin; terga 1, 3 and 6 sometimes with large, dark brown patches laterally ( Fig. 1 View FIGURE 1 F); subgenital plate without markings; ovipositor green, apex brown.

Etymology. Named in honor of Edward O. Wilson, a biologist, a writer, and an inspiration to several generations of scientists and naturalists.
Remarks. This species was very abundant in arid proteoid fynbos (Leipoldtville Sand Fynbos) biome ( Mucina and Rutherford 2006) between Citrusdal and Clanwilliam (Western Cape) ( Fig. 5 View FIGURE 5 F.) Most individuals were collected or seen during the day on tall shrubs, and in places their density was 5–10 individuals/m2.
