Figures 2–5 and 10 Diagnosis. Tegmina with distal region upward, forming an angle of 130° ( Fig. 4 ). Fourth branch of vein CuA and vein MP not connected by transverse vein ( Fig. 4 ). First three branches of vein CuA associated with hyaline regions with dark bands lined up ( Fig. 4 ). Apex of cercus with square expansion and small spiny ( Fig. 3K ). Lateral lobes of mesobasisternum forming an acute posterolateral angle of 40° slightly curved outward ( Fig. 3E ). Description. Holotype Male. Thorax . Lateral lobes of mesobasisternum anterolaterally, laterally and posteriorly straight, forming an acute posterolateral angle of 40° slightly curved outwards ( Fig. 3E ). Metabasisternum triangular, anteriorly straight ( Fig. 3E ). Wings . Tegmina broad, posterior margin somewhat convex, distal region upward, forming an angle of 130° ( Fig. 4 ). MA with four branches ( Fig. 4 ). Vein CuA connected with vein MP ( Fig. 4 ). Fourth branch of vein CuA, vein MP and first branch of vein MA with asymmetrical dark spots ( Fig. 4 ). First three branches of vein CuA associated with hyaline regions with dark bands lined up ( Fig. 4 ). FIGURE 2. Pictorial key for adult male species of Capanema nov. gen. Total length of left stridulatory file 2 mm , greater vein width of 0.4 mm and a total of 49 teeth ( Fig. 5A ). Right stridulatory file straight, with basal and apex region concave ( Fig. 5B ). Total length file of 1.8 mm, widest vein of 0.2 mm and total of 51 teeth. Teeth rectangular, narrow and far apart; teeth basal and apical minor ( Figs. 5B ). Abdomen . Apex of cercus with square expansion and small spiny, both with dark brown coloration ( Fig. 3K ). Internal male genitalia. Not examined. Coloration. Based on photos of preserved specimen ( Fig. 3 ). Body yellowish-brown. Eyes dark brown. Female: unknown. Etymology. The epithet is in apposition, capara [kapara] comes from the Brazilian indigenous language Tupi and means “crooked leaf”, in reference to the shape of tegmina this species, similar to crooked leaf.

FIGURE 5. Capanema capara sp. nov. , stridulatory file of male. A: left file; B: right file. Natural history notes. The specimen was collected in the Biological Reserve of Cuieras, in an Terra Firma forest, at a 40 m high scientific tower. This tower is designed to allow access to the forest canopy and has been widely used for insect collection for several years. In 2014, nightly collections with light traps were carried out monthly, method that the most effective for collecting Phaneropterinae . In 2017, malaise traps were set up at different heights in the tower and they remained active for one year. However, even with all this collection effort employed in the area, a single specimen from a malaise installed in the tower at 8 m from the ground was collected. Capanema capara sp. nov. is probably an exclusive resident of the forest canopy and his rarity may suggest that the natural density is very low (possibly temporal or spatial) or that the collection methods used until today are not effective for their capture.
