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

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

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

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

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 View Figure ).

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