Fastigium, gena and rostrum dark brown; Clypeus, labrum and labial palpi medium brown. Maxillary palpi: medium brown from the first to the third segment, fourth and fifth segment light brown, truncated apex. Antennae: medium brown, scape and pedicel medium brown; flagellum medium brown with white color in some segments. Thorax: ventrally light brown. Pronotum: medium brown, with light brown median and dark brown lateral lobes. Metanotal glands present. Forewings reduced, covering less than first abdominal tergite, without glandular hairs, inflated border, stridulatory vein and specialized veins; first tergite medium brown. Apical border rounded ( Fig. 1 D). Legs: uniformly medium brown. Femur III: medium brown with transversal dark brown stripe; tibia III medium brown, serrulated: 12 spines on inner and 10 on outer margin, in the spaces separating dorsal spurs. Abdominal tergites: medium brown dorsum, dark brown laterally; abdominal sternites pale yellow. Cerci medium brown. Terminalia: Phallic gland, secretor duct and orifice present. ( Fig. 8 A-C). Pseudepiphallic arms parallel, straight, not jagged ( Fig. 8 A), whit reduced secretor orifice (Fig, 8A); pseudepiphallic paramere 2 without teeth ( Fig. 8 A, B), with the same length of pseudepiphallic arms; pseudepiphallic paramere 1 draped in ventral view ( Fig. 8 B); ectophallic fold localized in the base of paramere ( Fig. 8 A), not visible in ventral view; ectophallic apodeme longer than endophallic apodeme, apex without two apical projections; endophallic sclerite present ( Fig. 8 B); rami short ( Fig. 8 A, C); Supra-anal plate dark brown, small, wider than long ( Fig. 8 D). Subgenital plate dark brown longer than wide, with inconspicuous indented apex ( Fig. 8 E). Female. Coloration darker than adult male. Fourth article of maxillary palpi medium brown. Ovipositor of the same length as cerci, medium brown. Terminalia: female copulatory papilla sclerotized, long and narrow ( Fig. 9 A, B), dorso-ventrally flattened ( Fig. 9 C), anterior portion waved and posterior portion smooth ( Fig. 9 A-C). Median valve of ovipositor as in figure 9D. Supra-anal plate triangular ( Fig. 9 E). Subgenital plate wider than long, without indented apex (9F). Nymphs. Males and females with coloration pattern similar to adults, although pronotum and abdomen darker than in adults, mixed with medium brown, light brown and white. Dorsal spurs of tibia III as the adult. Measurements in mm .
