Description. Male. Here we include features not included in the original description (Nickle 2003).

Wings. Left stridulatory file sinuous, with four curves regions from base to the apex (Fig. 13A). Total length of the left file 0.8 mm, larger width of vein 0.2 mm and with 67 teeth; basal and apical teeth small, increasing in size towards median portion of file (Fig. 13A). Teeth in median portion rectangular, narrow and very close to each other (Fig. 13A). Right file of teeth sinuous, forming three curves from base to the apex (Fig. 13B). Total length of the right file 0.6 mm, larger width of vein 0.1 mm and with 45 teeth; basal teeth increasing in size towards the median portion of the file, but smaller than the basal teeth of the left file (Fig. 13B). Teeth of median region of the right file similar to teeth of the median region of left file (Fig. 13B).

Abdomen. Tergite X with posterior margin expanded, forming a diagonally bilobated sclerite. (Fig. 11I –K). Cerci covered with numerous bristles, those at the base of the cerci longer (Fig. 11I –K). Cerci elongate, conical, curving inwards from the base to the beginning of the apical region, apical portion sharply curved outwards. Inner margin of cerci with a short and curved black projection before the apex. Styli connected postero-laterally to subgenital plate (Fig. 11J); short, slender, dorso-ventrally flattened, parallel to base of the median portion and curved inward at the apex (Fig. 11I –K); apex of styli blunt. Styli half the length of the cerci.

Phallus: Ejaculatory vesicles reniform (Fig. 14A–D). Upper folds of ventral lobe subtriangular, anteriorly connected, with the external margin sinuous (Fig. 14A–B). Anterior margin with two acuminate parallel projections (Fig. 14A–B). Lower folds asymmetrical, ending after margin of dorsal lobe and with several short bristles (Fig. 14A–B). Dorsal lobes narrow in the median portion and posterior portion expanded laterally, forming a structure similar to an inverted T (Fig. 14A–D). Dorsal folds narrow, elongated (Fig. 14C–D). Titillatory and tittilator sclerite undeveloped.

Wings. Tegmina long, with apex extending beyond the cerci apex (Fig. 11A). Costal margin of tegmen with base curved, median region slightly curved and posterior region straight; base of the anal margin of the tegmen expanded to the cubital vein, posterior region straight; apex blunt.

Coloration (description based on photos of live specimens). Body light green with darker marks (Fig. 16A–B). Antennal segments light brown with black bands apically. Eyes mainly yellow, dorsally yellow yolk color, and with a horizontal red band. Pronotum mainly light green, with the posterior portion of the pronotal disc brownish. Tegmina green, dorsally brownish. Legs light green and tarsi brown. Abdomen, cerci and subgenital plate light green.

Female. Similar to male (Fig. 15A–K), except for the following features: Abdomen. Cerci conical, longer than ovipositor base, slightly curved inward, with acuminate apex (Fig. 15I), and cerci covered by numerous bristles. Subgenital plate trapezoidal with bilobate apex (Fig. 15J). Ovipositor curved, with the base expanded and moderately narrowing to the beginning of the distal region; acuminate tip (Fig. 15K); ventral valves with delicate serrated margins in apical portion (Fig. 15K).

Coloration. Posterior region of the pronotum dorsally dark brown and with an elliptical black spot that connects to a similar spot on the base of the tegmen (Fig. 16C).

Nymph. Very similar to the adult, with differences in the coloration of the terminalia (Fig. 17A–B). Apex of hind femora and tibiae brownish. First and second abdominal segments with yellowish spot dorsally.

Geographical records. Peru: Loreto; Brazil (new record): Amazonas (Fig. 19).
