Brachyamytta mcculloughae View in CoL n. sp.

( Figs. 3 View FIGURE 3 A, B, K; 4F, P; 7F)

Differential diagnosis. This species is similar to B. maculipes n. sp., but differs in the general coloration, the shape of the male cerci ( Figs. 3 View FIGURE 3 A, B; 3C, D), the shape of the tegmen ( Figs. 4 View FIGURE 4. A – J P, Q), and the significantly longer stridulatory file.

Description.

[General.] As in generic ( Fig. 7 View FIGURE 7 F); female unknown.

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

Wings. Tegmen distinctly narrowed towards apex, not reaching middle of abdomen; anterior margin straigh. Costal field not dilated at base; veins Sc and R diverging towards apex of tegmen; left stridulatory area with large, fully developed, roughly rectangular mirror ( Fig. 4 View FIGURE 4. A – J P). Stridulatory file flat, weakly bent, with 88 teeth, 1.2 mm long, 0.06 mm wide ( Fig. 4F View FIGURE 4. A – J ).

Abdomen. Cercus long and slender, straight, bent outwards under right angle in apical fourth; apex tapered, bent slightly downwards ( Figs. 3 View FIGURE 3 A, B). Subgenital plate broadly trapezoidal; styli vertical, pointing down, cylindrical, about twice as long as wide, parallel, very close together, nearly touching.

Coloration. Coloration reddish brown; antennal scapus without markings; antennae concolorous; eyes uniformly colored; face without darker markings; occiput with dark brown markings around posterior margins of eyes; pronotum light brown dorsally, lateral lobe with small, dark brown patch, and lower edge of pronotum dark brown; prozona light brown; tegmen with small, brown patch behind stridulatory area; veins light, with membrane between veins brown; hind wing hyaline; genicular lobes of front legs without markings; hind femur with dark brown patch at base and wide, irregular, dark brown band in proximal third ( Fig. 3 View FIGURE 3 K); hind tibia brown.

Measurements (2 males). body w/o wings: 10–11 (10.5±.7); pronotum: 4–4.3 (4.2±.2); tegmen: 3–3.7 (3.4±.5); hind femur: 10 mm.
