Type-species. Ibityraboia caraguata sp. nov.

Grammatical gender. Feminine.

Diagnosis. Fastigium-vertex proportionally small in relation to head (about 5x smaller). Basal half widened with small frontal triangular projection and narrow apical half, curved and acuminate, in lateral view ( Fig. 2B View FIGURE 2 ). Tergite X with posterior margin expanded, forming two subtriangular projections slightly inward curved, in dorsal view ( Fig. 2J View FIGURE 2 ). Cercus elongated, wide, anteriorly straight, and posteriorly inward curved; apical region with small curved internal spine with black apex; apex of cercus curved and acuminate, with a keel on the inner margin ( Figs. 3I–J View FIGURE 3 ). Ejaculatory vesicle rounded ( Figs. 5A–D View FIGURE 5 ). Titillator segmented as two large sclerites, anteriorly curved, opposing and posteriorly parallel straight ( Figs. 5A–D View FIGURE 5 ). Ovipositor straight with apex of triangular.

Description.

Head dorsally with elongated fastigium-vertex, length equivalent to 1.5x the width of the base, in lateral view ( Fig. 2D View FIGURE 2 ); basal half widened with small frontal triangular projection and narrow apical half, curved and acuminate, in lateral view ( Fig. 2B View FIGURE 2 ). Globular eyes ( Figs. 2B–D View FIGURE 2 ). Head laterally enlarged, gena with smooth margins, in frontal view ( Fig. 2B View FIGURE 2 ). Pronotal disc rectangular, without carina, with several small rounded depressions, in dorsal view ( Fig. 2C View FIGURE 2 ); Dorsal-lateral suture slightly curved ( Figs. 2C–D View FIGURE 2 ). Furcal suture curved ( Fig. 2C View FIGURE 2 ). Dorsal-lateral suture and furcal suture concolorous with pronotal disc ( Fig. 2C View FIGURE 2 ). Tegmina narrow with rounded apex ( Fig.3 View FIGURE 3 ). Vein R slightly sinuous and with small branches, most of branches bifurcated near the apex ( Fig. 3 View FIGURE 3 ). Vein MP with three bifurcated branches reaching wing margin ( Fig. 3 View FIGURE 3 ). Vein MA with only one branch ( Fig. 3 View FIGURE 3 ). Vein CuP with one bifurcation and vein CuA with six bifurcated branches reaching wing margin ( Fig. 3 View FIGURE 3 ). Subcostal vein bifurcated near the apex ( Fig. 3 View FIGURE 3 ). Fore femur slightly sinuous, with apex narrower than the base, presence of three ventral spines and a pair of apical spines ( Fig. 2F View FIGURE 2 ). Fore tibia straight, with partially closed tympanum and six pairs of spines in ventral region ( Fig. 2F View FIGURE 2 ). Mid femur slightly sinuous, with four ventral spines and a small pair of apical spines ( Fig. 2G View FIGURE 2 ). Mid tibia with enlarged basal half with eight pairs of small ventral spines ( Fig. 2G View FIGURE 2 ). Hind femur enlarged at basal half, with seven long curved ventral spines and a small pair of apical spines ( Figs. 2H View FIGURE 2 ). Hind tibia straight, narrow, with several small ventral and dorsal spines ( Figs. 2H View FIGURE 2 ). All legs with short bristles ( Figs. 2F–H View FIGURE 2 ). Tergite X with posterior margin expanded, forming two subtriangular projections slightly inward curved and with rounded apex, in dorsal view ( Fig. 2J View FIGURE 2 ). Cercus elongated, wide, anteriorly straight, and posteriorly inward curved; apical region with small curved internal spine with black apex; apex of cercus curved and acuminate, with a keel on the inner margin ( Figs. 2I–J View FIGURE 2 ). Subgenital plate elongated, medially narrow and apically bifurcated ( Figs. 2I–J View FIGURE 2 ). Stylus small, ensiform-shaped and curved outward ( Figs. 2I–J View FIGURE 2 ). Ejaculatory vesicle rounded ( Figs. 5A–D View FIGURE 5 ). Titillator segmented as two large sclerites, anteriorly curved, opposing and posteriorly parallel straight ( Figs. 5A–D View FIGURE 5 ). Apodemes sclerites large and narrow ( Fig. 5A–D View FIGURE 5 ).

Additional taxonomic notes. Ibityraboia gen. nov. appears most closely related with the type-genus of Copiphorini , Copiphora Serville, 1831 . Copiphora currently has 26 Neotropical species and 1 Ethiopian species. The group needs taxonomic review and, therefore, we opt to compare the new genus with the type-species of Copiphora , Copiphora longicauda Serville, 1831 ( Fig.1 View FIGURE 1 ). Ibityraboia gen. nov. differs from Copiphora by having: fastigium-vertex almost 5x smaller than head (versus fastigium-vertex larger than head in Copiphora ); fastigium-vertex curved in lateral view, and laterally rounded in frontal view (versus fastigium-vertex straight in lateral view, with two triangular lateral projections in frontal view in Copiphora ); subgenital plate short, round, with two long projections on apex (versus subgenital plate elongated, sub-triangular, with two short projections on apex in Copiphora ); concealed male genitalia anteriorly and posteriorly straight, laterally concave (versus internal male genitalia anteriorly acuminated, laterally and posteriorly elongated in Copiphora ); ejaculatory vesicles rounded (versus ejaculatory vesicles ensiform in Copiphora ); titillator segmented as two large sclerites (versus titillator segmented as two short sclerites in Copiphora ).

Etymology. The epithet is in apposition, Ibityraboia comes from the Brazilian indigenous language Tupi: Ibityra [ybytyra] = hill, mountain + boia [îyboîa] = jibóia, red-tailed boa ( Boa constrictor ), in reference to the Serra da Jiboia ( Boa constrictor mountain). The epithet is a homage to the type locality of this new katydid.

Distribution. Brazil (Bahia).
