Figures 2–10  
 Type-species. Capanema pocanga sp. nov., here designated.   
 Grammatical gender. Feminine.   
 Diagnosis. Fore femur without ventral spines; Fore tibia with closed tympanum (Figs. 3F, 6F). Mid tibia without dorsal spines (Figs. 3G, 6G). Vein CuA with four bifurcations branches reaching wing margin; fourth and fifth branches connected by transverse vein, forming a pentagonal cell (Figs. 4, 7). Vein MP with a single branch (Figs. 4, 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, 7); other branches of CuA and MP with a narrow hyaline region also with several small circular spots, forming stripes (Fig. 4) or asymmetric spots (Fig. 7).   
 Description. Head dorsally round and frontally flat, in lateral view (Figs. 3A, 6A). Globular eyes (Figs. 3A, 6A). Pronotal disc rectangular, without carina, with several small bristles, anteriorly and laterally straight and posteriorly convex, in dorsal view (Figs. 3C, 6C). Dorsal-lateral suture sinuous and black (Figs. 3C–D, 6C–D). Furcal suture concolorous with pronotal disc (Figs. 3C, 6C). Mesobasisternum sublozenge-shaped, anteriorly convex (Figs. 3E, 6E). Lateral lobes of metabasisternum anterolaterally convex, laterally and posteriorly straight, posterolaterally forming an angle of 140° (Figs. 3E, 6E). Vein R sinuose and with small branches, most of them bifurcated near the apex (Figs. 4, 7). Vein MP with a single branch (Figs. 4, 7). Vein CuA with four bifurcations branches reaching wing margin; fourth and fifth branches connected by transverse vein, forming a pentagonal cell (Figs. 4, 7). Left stridulatory file curved; Teeth in basal half larger and more widely spaced (Figs. 5A, 8A). Fore femur slightly curved and without ventral spines (Figs. 3F, 6F). Fore tibia with close tympanum and four spines in ventral region (Figs. 3F, 6F). Mid femur straight and without ventral spines (Figs. 3G, 6G). Mid tibia with enlarged basal half, without dorsal spines and five ventral spines (Figs. 3G, 6G). Hind femur enlarged at basal half (Figs. 3H, 6H). All legs with short bristles (Figs. 3F–H, 6F–H). Cercus inward curved with rounded apical region (Figs. 3J, 6J). Subgenital plate trapezoidal (Figs. 3I, 6I). Stylus small, rectangular with rounded apex (Figs. 3I–J, 6I–J). Titillator sclerite absent (Fig. 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.
