Brachyamytta maculipes n. sp.

(Figs. 3 C, D, G, H; 4G, Q; 7A, B)

Differential diagnosis. This species is similar to B. mcculloughae, but differs in the general coloration, the shape of the male cerci (Figs. 3 A, B; 3C, D), the shape of the tegmen (Figs. 4 P, Q), and the significantly shorter stridulatory file.

Description.

General. As in generic (Figs. 7 A, B).

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

Wings. Tegmen distinctly narrowed towards apex, not reaching middle of abdomen; anterior margin rounded; hind wing rudimentary, about as long as fifth of tegmen. 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 Q). Stridulatory file flat, weakly bent, with 87 teeth, 0.8 mm long, 0.05 mm wide (Fig. 4G).

Abdomen. Cercus long and slender, straight, bent outwards under right angle in apical fourth; apex tapered and distinctly bent downwards (Figs. 3 C, D). Subgenital plate broadly trapezoidal; styli vertical, pointing down; cylindrical, about twice as long as wide, parallel, very close together, nearly touching. Female subgenital plate with two narrow, rounded lobes on posterior margin (Fig. 3 G).

Ovipositor. Ovipositor normally developed, slightly curved; shorter than hind femur (ratio femur/ovipositor 1.83–1.91) (Fig. 3 H); apex with both valvulae smooth; pointed, dorsal edge of upper valvula parallel to lower valvula;.

Coloration. Coloration olive green; antennal scapus without markings; antennae concolorous; eyes uniformly colored; face without darker markings; occiput without markings; pronotum olive green, without markings; prozona green; tegmen with small, brown patch behind stridulatory area; hind wing hyaline; genicular lobes of front legs without markings; hind femur green, with small, gray, dorsal patch in proximal third; hind tibia olive green.

Measurements (2 males, 2 females). female; body w/o wings: male 9–9.5 (9.3±.4), female 9.5–11 (10.3±1.1); pronotum: male 4, female 4; tegmen: male 3–3.5 (3.3±.4), female 3–3.5 (3.3±.4); hind femur: male 9.5–10 (9.8±.4), female 10.5–11 (10.8±.4); ovipositor: 5.5–6 (5.8±.4) mm.

Etymology. The specific epithet refers to the presence of darker maculation on the hind femora in this species.
