Type-species. Capanema pocanga sp. nov., here designated.
Grammatical gender. Feminine.
Diagnosis. Fore femur without ventral spines; Fore tibia with closed tympanum ( Figs. 3F View FIGURE 3 , 6F View FIGURE 6 ). Mid tibia without dorsal spines ( Figs. 3G View FIGURE 3 , 6G View FIGURE 6 ). Vein CuA with four bifurcations branches reaching wing margin; fourth and fifth branches connected by transverse vein, forming a pentagonal cell ( Figs. 4 View FIGURE 4 , 7 View FIGURE 7 ). Vein MP with a single branch ( Figs. 4 View FIGURE 4 , 7 View FIGURE 7 ). First branch of the CuA vein with a hyaline region associated with small circular patches grouped, forming black stripes aligned laterally on both sides of the branch ( Figs. 4 View FIGURE 4 , 7 View FIGURE 7 ); other branches of CuA and MP with a narrow hyaline region also with several small circular spots, forming stripes ( Fig. 4 View FIGURE 4 ) or asymmetric spots ( Fig. 7 View FIGURE 7 ).
Description. Head dorsally round and frontally flat, in lateral view ( Figs. 3A View FIGURE 3 , 6A View FIGURE 6 ). Globular eyes ( Figs. 3A View FIGURE 3 , 6A View FIGURE 6 ). Pronotal disc rectangular, without carina, with several small bristles, anteriorly and laterally straight and posteriorly convex, in dorsal view ( Figs. 3C View FIGURE 3 , 6C View FIGURE 6 ). Dorsal-lateral suture sinuous and black ( Figs. 3C–D View FIGURE 3 , 6C–D View FIGURE 6 ). Furcal suture concolorous with pronotal disc ( Figs. 3C View FIGURE 3 , 6C View FIGURE 6 ). Mesobasisternum sublozenge-shaped, anteriorly convex ( Figs. 3E View FIGURE 3 , 6E View FIGURE 6 ). Lateral lobes of metabasisternum anterolaterally convex, laterally and posteriorly straight, posterolaterally forming an angle of 140° ( Figs. 3E View FIGURE 3 , 6E View FIGURE 6 ). Vein R sinuose and with small branches, most of them bifurcated near the apex ( Figs. 4 View FIGURE 4 , 7 View FIGURE 7 ). Vein MP with a single branch ( Figs. 4 View FIGURE 4 , 7 View FIGURE 7 ). Vein CuA with four bifurcations branches reaching wing margin; fourth and fifth branches connected by transverse vein, forming a pentagonal cell ( Figs. 4 View FIGURE 4 , 7 View FIGURE 7 ). Left stridulatory file curved; Teeth in basal half larger and more widely spaced ( Figs. 5A View FIGURE 5 , 8A View FIGURE 8 ). Fore femur slightly curved and without ventral spines ( Figs. 3F View FIGURE 3 , 6F View FIGURE 6 ). Fore tibia with close tympanum and four spines in ventral region ( Figs. 3F View FIGURE 3 , 6F View FIGURE 6 ). Mid femur straight and without ventral spines ( Figs. 3G View FIGURE 3 , 6G View FIGURE 6 ). Mid tibia with enlarged basal half, without dorsal spines and five ventral spines ( Figs. 3G View FIGURE 3 , 6G View FIGURE 6 ). Hind femur enlarged at basal half ( Figs. 3H View FIGURE 3 , 6H View FIGURE 6 ). All legs with short bristles ( Figs. 3F–H View FIGURE 3 , 6F–H View FIGURE 6 ). Cercus inward curved with rounded apical region ( Figs. 3J View FIGURE 3 , 6J View FIGURE 6 ). Subgenital plate trapezoidal ( Figs. 3I View FIGURE 3 , 6I View FIGURE 6 ). Stylus small, rectangular with rounded apex ( Figs. 3I–J View FIGURE 3 , 6I–J View FIGURE 6 ). Titillator sclerite absent ( Fig. 9 View FIGURE 9 ).
Additional taxonomic notes. Capanema gen. nov. appears most closely related to Tropicophyllum Koçak & Kemal, 2008 . Capanema gen. nov., differs from both genera by black bands marginally associated with the branches of vein CuA (versus absent in Tropicophyllum ); Vein CuA four branches reaching wing margin (versus three branches in Tropicophyllum ); Third and fourth branches of vein CuA forming a pentagonal cell (versus tetragonal cell in some species of Tropicophyllum ).
Etymology. The epithet is in apposition, capanema comes from the Brazilian indigenous language Nheengatu: Ca meaning “forest” + panema meaning “unlucky”, used for difficult hunting grounds. The name is given about the rarity of this katydid, having been collected only one specimen in an area widely collected for years.
