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. 13AView FIGURE 13). 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. 13AView FIGURE 13). Teeth in median portion rectangular, narrow and very close to each other ( Fig. 13AView FIGURE 13). Right file of teeth sinuous, forming three curves from base to the apex ( Fig. 13BView FIGURE 13). 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. 13BView FIGURE 13). Teeth of median region of the right file similar to teeth of the median region of left file ( Fig. 13BView FIGURE 13).

Abdomen. Tergite X with posterior margin expanded, forming a diagonally bilobated sclerite. ( Fig. 11I –KView FIGURE 11). Cerci covered with numerous bristles, those at the base of the cerci longer ( Fig. 11I –KView FIGURE 11). 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. 11JView FIGURE 11); short, slender, dorso-ventrally flattened, parallel to base of the median portion and curved inward at the apex ( Fig. 11I –KView FIGURE 11); apex of styli blunt. Styli half the length of the cerci.

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

Wings. Tegmina long, with apex extending beyond the cerci apex ( Fig. 11AView FIGURE 11). 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 –BView FIGURE 16). 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 –KView FIGURE 15), except for the following features: Abdomen. Cerci conical, longer than ovipositor base, slightly curved inward, with acuminate apex ( Fig. 15IView FIGURE 15), and cerci covered by numerous bristles. Subgenital plate trapezoidal with bilobate apex ( Fig. 15JView FIGURE 15). Ovipositor curved, with the base expanded and moderately narrowing to the beginning of the distal region; acuminate tip ( Fig. 15KView FIGURE 15); ventral valves with delicate serrated margins in apical portion ( Fig. 15KView FIGURE 15).

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. 16CView FIGURE 16).

Nymph. Very similar to the adult, with differences in the coloration of the terminalia ( Fig. 17A –BView FIGURE 17). 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. 19View FIGURE 19).
