Bioacoustics of Brinckiella karooensis

Thorax. Lateral lobe of pronotum about twice as long as high; anterior margin of pronotum flat; broadly rounded; metazona flat, posterior edge of metazona broadly rounded. Legs. Genicular lobes of front femur armed with one spine on posterior (outer) and two spines on anterior (inner) side. Front tibia usually unarmed dorsally, except for one or two apical spines. Genicular lobes of mid femur armed with single spines on both sides. Genicular lobes of hind femur unarmed. Wings. Stridulatory file flat, weakly bent, 6.0 mm long, 0.2 mm wide, with 47 teeth ( Fig. 1 N.) Abdomen. Tenth tergite with posterior edge sclerotized and somewhat extended, completely covering epiproct. Cercus short, nearly straight; apex slightly thickened, blunt; unarmed ( Fig. 3 F); phallus mostly membranous, with central, inner lobes somewhat sclerotized and covered with minute teeth ( Fig. 3 B.) Subgenital plate broadly trapezoidal, straight apically; styli cylindrical, more than 3 times as long as wide, parallel, widely separated and held horizontally ( Fig. 2 Q.) Female subgenital plate about 2.5 times as wide as long, with two short lateral lobes and convex central portion, posterior lobes rounded ( Fig. 2 I.) Ovipositor. Ovipositor strongly curved, shorter than half of hind femur, dorsal edge of upper valvula parallel to lower valvula; apex pointed, with minute dentitions on both lower and upper valvulae ( Fig. 2 J.) Coloration. Coloration light green ( Figs. 5 C–D), antennae concolorous; antennal scapus without markings. Face pale green; eyes uniformly colored. Pronotum green, with dark and light stripes on upper edge of lateral lobe, continuous with those on thorax and abdomen. 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; genicular lobes of front legs without markings; abdominal sterna without markings; abdominal terga with horizontal dark and light stripes laterally, area between stripes sometimes lighter then rest of abdomen; subgenital plate without markings; ovipositor green, apex brown.
