Abdomen. Cercus slightly curved, apex acuminate ( Figs. 41H–J View FIGURE 41 ). Subgenital plate triangular, apex rounded and stylus absent ( Fig. 41H View FIGURE 41 ). Ovipositor curved; apex of ventral valve surpassing the apex of dorsal valve; apical region of dorsal and ventral valve with rectangular teeth ( Fig. 41J View FIGURE 41 ).
Coloration. Described based on photos of live specimens ( Fig. 42B View FIGURE 42 ). General color of the body light green. Eyes dark green with whitish spots. Apical half of tegmina and apex of membranous wing with yellow edges. Tegmina with Cu and M veins marginally with small dark green spots and several small rounded yellow spots; margins of tegmina and apex of the membranous wing with a narrow yellow band. Abdomen whitish. Ovipositor with whitish base and light green apex.
Etymology. The epithet is in apposition, igapó comes from the Brazilian indigenous language Nheengatu and means “river of roots”, this being the popular name given to the environment of seasonally flooded Amazonian forests in which the specimens were found.
Distribution. Brazil: Amazonas ( Fig. 45 View FIGURE 45 ).

Observation of behavior. A. igapo sp. nov. is one of the most fascinating species of the genus, as it specializes in seasonally flooded forest environments of várzea (bathed by whitewater rivers) and igapó (bathed by blackwater rivers) ( Fig. 43A View FIGURE 43 ). The specimens were collected in Ipixuna, Negro, Nhamundá and Solimões rivers, occurring in area of endemism of the Guianas, Imeri and Inambari. Collections and observations were carried out at night in boats during the flood period (about 10m deep). It was observed that the specimens were between 20 cm to 200 cm from the surface of the water, usually at the tips of the branches of the plants ( Fig. 43B View FIGURE 43 ). In Reserva de Desenvolvimento Sustentável Amanã, during May 2024, a female was observed laying eggs on a leaf about 15 cm from the surface of the water ( Fig. 44A–B View FIGURE 44 ).
