Bioacoustics of Brinckiella wilsoni

Thorax. Anterior margin of pronotum flat; broadly rounded; metazona flat, posterior edge of metazona slightly raised ( Fig. 1 C), straight when seen from above ( Fig. 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 L.) Abdomen. Tenth tergite unmodified. Cercus short, slightly bent inwards, distinctly thickened basaly ( Fig. 3 G); straight when seen from side; apex tapered, with small apical tooth. Phallus entirely membranous, without sclerotized elements ( Fig. 3 C.) Subgenital plate broadly trapezoidal, straight apically ( Fig. 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 G). Ovipositor. Ovipositor slightly curved, shorter than half of hind femur, dorsal edge of upper valvula parallel to lower valvula ( Fig. 3 K); apex pointed, with minute dentitions on both lower and upper valvulae ( Fig. 2 H). Egg. Egg elongate, cylindrical in crosssection, straight ( Fig. 3 N). Coloration. Coloration green, with variable markings ( Figs. 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 F); subgenital plate without markings; ovipositor green, apex brown.
