( Figs.1 View FIGURE 1 D, 8 and 9)

Etymology. The specific name is in honor to the orthopterologist and cytogeneticist Alejo Mesa.

Holotype: Brasil, Amazonas, Manaus, Tarumã-Mirim River, 03º02’S, 60º17’W, Male holotype: TM BOF 32, 24.iii.1977. Adis, J. leg. MZSP.

Diagnosis: Male forewing without glandular hairs, stridulatory vein and glandular border ( Fig. 1 View FIGURE 1 D); Metanotal glands present. Male terminalia: pseudepiphallic arms parallel, straight, not jagged ( Fig. 8 View FIGURE 8 A), with reduced secretor orifice (Fig, 8A); pseudepiphallic paramere 2 not jagged ( Fig. 8 View FIGURE 8 A, B); pseudepiphallic paramere 1 draped in ventral view ( Fig. 8 View FIGURE 8 B); ectophallic fold localized in the base of paramere ( Fig. 8 View FIGURE 8 A), not visible in ventral view; ectophallic apodeme longer than endophallic apodeme, apex without two apical projections; rami short ( Fig. 8 View FIGURE 8 A, C). Female copulatory papilla sclerotized, long and narrow ( Fig. 9 View FIGURE 9 A, B), dorso-ventrally flattened ( Fig. 9 View FIGURE 9 C), anterior portion rugged and posterior portion smooth ( Fig. 9 View FIGURE 9 A-C).

Male. Head: vertex dark brown with five light stripes, three toward each ocellus and two laterals toward the compound eye. 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 View FIGURE 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 View FIGURE 8 A-C). Pseudepiphallic arms parallel, straight, not jagged ( Fig. 8 View FIGURE 8 A), whit reduced secretor orifice (Fig, 8A); pseudepiphallic paramere 2 without teeth ( Fig. 8 View FIGURE 8 A, B), with the same length of pseudepiphallic arms; pseudepiphallic paramere 1 draped in ventral view ( Fig. 8 View FIGURE 8 B); ectophallic fold localized in the base of paramere ( Fig. 8 View FIGURE 8 A), not visible in ventral view; ectophallic apodeme longer than endophallic apodeme, apex without two apical projections; endophallic sclerite present ( Fig. 8 View FIGURE 8 B); rami short ( Fig. 8 View FIGURE 8 A, C); Supra-anal plate dark brown, small, wider than long ( Fig. 8 View FIGURE 8 D). Subgenital plate dark brown longer than wide, with inconspicuous indented apex ( Fig. 8 View FIGURE 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 View FIGURE 9 A, B), dorso-ventrally flattened ( Fig. 9 View FIGURE 9 C), anterior portion waved and posterior portion smooth ( Fig. 9 View FIGURE 9 A-C). Median valve of ovipositor as in figure 9D. Supra-anal plate triangular ( Fig. 9 View FIGURE 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. (Male (n=6) min. – max. values, followed by female (n=13) min. – max. values) Body length: 4.00–5.12, 4.52–5.64; head width: 0.82–0.93, 0.86–0.98; intra-ocular distance: 0.47, 0.40–0.52; pronotum length: 0.75–0.93, 0.88–1.01; pronotum width: 0.68–0.95, 0.86–0.97; femur III length: 2.80–3.00, 2.91–3.39; tibia III length: 2.13–2.40, 2.60–3.82; female ovipositor: 2.33–2.59.
