Figures 11 View FIGURE 11 , 14–19 View FIGURE 14 View FIGURE 15 View FIGURE 16 View FIGURE 17 View FIGURE 18 View FIGURE 19

Diagnosis. Tegmina with first branch of MP vein and last branch of CuA vein connected by two transverse veins, forming a hexagonal cell ( Fig. 15 View FIGURE 15 ). Lateral lobes of mesobasisternum laterally straight, posteriorly slightly convex, posterolaterally forming an angle of 60° and blunt tip ( Fig. 14E View FIGURE 14 ).

Description. Holotype Female.

Thorax. Lateral lobes of mesobasisternum anterolaterally convex, laterally straight and posteriorly slightly convex, posterolaterally forming an angle of 60° and blunt tip ( Fig. 14E View FIGURE 14 ). Lateral lobes of metabasisternum anterolaterally and laterally straight, posteriorly convex, posterolaterally forming an angle of 90° ( Fig. 14E View FIGURE 14 ).

Wings. First branch of MP vein and last branch of CuA vein connected by two transverse veins, forming a hexagonal cell ( Fig. 15 View FIGURE 15 ).

Coloration. Described based on photos of live specimens ( Fig. 16 View FIGURE 16 ). Body general color light green, with yellow asymmetric regions. Eyes with the upper half yellow and lower half dark purple. Dorsal region of the head and pronotal disc with dark coloring and numerous small black punctuations. Thorax laterally with a dark purple spot. Tegmina dark green with small yellow spots; veins Cu and M associated with wide hyaline regions, marginally with small black spot. Fore femur dark yellow with three light purple bands with small black punctuations. Mid femur with dark green basal half with whitish spots and dark yellow apical half with two light purple bands with small black punctuations. Hind femur dark green with the apical region with two light purple bands separated by a gray band. All femora with yellow ventral spines. Fore and mid tibia grayish-purple with three bands formed by numerous black punctuations. Hind tibia grayish-purple with four bands formed by small black dots. Tarsi I to IV dark yellow; tarsus V light purple with small black punctuations. Abdomen dorsally with three large asymmetrical light pink spots, with dark purple edges and small black spots inside the spot; ventrally whitish. Ovipositor light green. Cercus light green with light purple apex.

Male: unknown.

Nymph. Nymphs are very similar to adults, with differences only in the coloration and terminalia morphology ( Fig. 17A–B View FIGURE 17 ). Compound eyes with the upper half beige and lower half dark purple. Body light green. Dorsal region of head and pronotal disc with several small black spots. Pronotal disc light green, dorsally keeled with a beige stripe. Thorax laterally with a dark purple spot. Legs coloration similar to that of adults, with the exception of dark yellow bands, which in nymphs have a beige coloration. Abdomen dorsally with three large asymmetrical light pink spots, with dark purple edges and small black spots inside the spot; ventrally slightly whitish.

Etymology. The epithet is in apposition, from the Brazilian indigenous Tupi language: pinima meaning “painted, spotted, with spots” + una meaning “black”, in reference to the various black spots on the tegmina of this katydid.

Natural history notes. Tukunha pinimauna   sp. nov. is registered in Terra Firma forest ( Fig. 18 View FIGURE 18 ) in the endemic areas of Guiana and Tapajós. All adult specimens were collected using light traps and a single nymph was found in shrubby vegetation on leaves of Triplophyllum discksonioides   ( Tectariaceae   )( Fig. 17B View FIGURE 17 ). It is likely that adults inhabit the upper strata of the forest (understory and canopy), as observed in most phaneropterine species in Central Amazonia.
