Description. Male and female as shown in Figs. 1 A, B, 2A, B, and 4A, B. Head . ( Figs. 1 C, D, E and 2C, D, E). Face a little longer than broad ( Figs. 1 C, 2C). Eyes vertically elongated, large in relation to the size of the head, and weakly protruding ( Figs. 1 C, D, E and 2C, D, E). Frons flat and smooth. Thorax and wings . Pronotal disc very convex and metazona strongly projecting behind ( Fig. 1 D). Anterior margin of pronotum straight; posterior margin strongly convex ( Fig. 1 E). Lateral lobes rounded. Humeral sinus poorly developed ( Figs. 1 A and D). Mesosternum with two tubercles with rounded tips. Metasternum unarmed. Fore femora (n=4) armed ventrally with 2 spines on inner and 3 on outer margins; mid and hind femora unarmed. Foretibiae armed ventrally with 5 movable spines on inner and 6 on outer margins. Mid tibiae armed ventrally with 2–4 movable spines on inner and 4–5 on outer margins. Hind tibiae armed dorsally with 21–28 spines on inner and 20–28 on outer margins. Genicular lobes unarmed. Tarsal claws of all legs similar, with little denticles ventrally. Tympana on fore tibiae open; tympanal slits facing laterally ( Figs. 1 F and G). Abdomen . Dorsal surface of tergites smooth, unmodified. Genus Mandibles Tegmen Cerci Paraprocts Subgenital plate Titillator Description of male. Head in frontal view more rounded than in female. Mandibles strongly asymmetrical; left mandible longer ( Figs. 1 C and D). Pronotum is more bulging than in female, reaching the second abdominal tergite ( Figs. 1 A and D). Prosternum armed. Thoracic auditory spiracle was not observed. Tegmina as shown in Figs. 1 H and I, almost entirely covered by pronotum. Stridulatory region well-developed, and both tegmina translucent. Left stridulatory file (n=1) 0.346 mm long, with 59 teeth; width of the smallest teeth 0.009 mm and of the largest ones 0.032 mm . Right stridulatory file 0.446 mm long; width of the smallest teeth 0.016 mm and of the largest ones 0.024 mm ; number of teeth 33 ( Figs. 3 E and F). Right mirror rectangular. Tergite X as long as the remaining tergites. Epiproct modified in two elongated ramifications, projecting behind, as long as the cerci, and apically covered with coarse bristles ( Figs. 3 B and C); the two ramifications are subapically in contact. Paraprocts modified in an elongated sclerite, longer than epiproct and covered with coarse bristles. The two paraprocts are apically in contact and located below the epiproct ( Fig. 3 B). Cercus simple, curved inward, width decreasing from the base to the apex; apical portion strongly sharpened ( Figs. 3 A, B, and C). Subgenital plate as long as cerci, with a short and V-shaped emargination at apex ( Fig. 3 D). Styli as long as the subgenital plate ( Figs. 3 C and D). Phallus devoid of titillators.

Head in frontal view more triangular than in male. Mandibles symmetrical ( Fig. 2 C). Pronotal disc reaching the first abdominal tergite; tegmina partially covered by pronotum ( Figs. 2 B, D, and E). Prosternum armed with two tubercles with rounded tips. Thoracic auditory spiracle is composed by a tiny cavity which is partially covered by a bilobed sclerite. Subgenital plate strongly modified and saclike, with a long appendix ( Figs. 2 F and G). Ovipositor shorter than hind femur, upcurved; dorsal valves about three times as wide as ventral ones; apex of ovipositor narrowly rounded ( Figs. 2 A, F, H and I). Coloration. General coloration light greenish ( Fig. 4 ). Metazona, tegmina, mandibles, movable spines of fore- and middle tibiae, tarsomeres and apex of male cerci light brownish. Flagellomeres and apical part of ovipositor dark brownish. Immature with little brownish spots on pronotum, on head above the eyes, and legs ( Fig. 5 ). Measurements (mm). Two males: TL 11.5–12; PL 4–4.8; PW 2.8; TegL 3.5; FF 3–3.5; FT 4; HF 10–11; HT 9.5–10. Two females: TL 11–14; PL 4–4.2; PW 2.8–3; TegL 2; FF 3.5; FT 4–4.3; HF 11; HT 11; OL 4.5.
