Brachyamytta rapidoaestima View in CoL n. sp.

( Figs. 3 View FIGURE 3 E, F, I, J, L; 4E, O; 7C–E)

Differential diagnosis. B. rapidoaestima can be distinguished from the remaining species of the genus by the shape of male cerci (apex unmodified, bent outwards under right angle in other Brachyamytta spp.), and coloration (stridulatory area bright yellow, posterior margin of pronotum dark brown.)

Description.

General. As in generic ( Figs. 7 View FIGURE 7 C–E).

Legs. Front tibia with 4 spines on posterior and 4 on anterior ventral margin. Mid tibia with 2 spines on posterior and 3 on anterior ventral margin.

Wings. Tegmen distinctly narrowed towards apex, not reaching middle of abdomen; anterior margin straight. Costal field not dilated at base; veins Sc and R close together, parallel along their entire length; left stridulatory area with large, fully developed, roughly rectangular mirror ( Fig. 4 View FIGURE 4. A – J O). Stridulatory file flat, weakly bent, with 100 teeth, 1.05 mm long, 0.05 mm wide ( Fig. 4E View FIGURE 4. A – J ).

Abdomen. Cercus unarmed, long and slender, slightly bent inwards; apex narrowed, blunt ( Figs. 3 View FIGURE 3 E, F); styli horizontal; cylindrical, about twice as long as wide, parallel, separated by small gap. Female subgenital plate with two narrow lobes on posterior margin; posterior lobes acute to rounded, slightly divergent ( Fig. 3 View FIGURE 3 I).

Ovipositor. Ovipositor normally developed, slightly curved; shorter than hind femur (ratio femur/ovipositor 1.68–1.75) ( Fig. 3 View FIGURE 3 J); apex with both valvulae smooth; pointed, dorsal edge of upper valvula parallel to lower valvula;.

Coloration. Coloration green, with brown and yellow markings; antennal scapus without markings; antennae concolorous; eyes uniformly colored; face without darker markings; occiput without markings; pronotum light green (Ghanaian population) to brown, posterior edge of metazone darker brown; prozona light brown; tegmen with basal part bright yellow, and small, brown patch behind stridulatory area; hind wing hyaline; genicular lobes of front legs without markings; hind femur with basal part light green, apical part gradually turning brown; hind tibia brown.

Measurements (2 males, 5 females). body w/o wings: male 10, female 9–10 (9.7±.4); pronotum: male 4.5, female 4–4.5 (4.3±.3); tegmen: male 3.3, female 3.3–4 (3.6±.4); hind femur: male 10, female 10–10.5 (10.1±.2); ovipositor: 6 mm.
