Diagnosis . Concealed male genitalia with large titillator as a pair sclerites hook–shaped, which protrude from the abdomen and enveloped by subgenital plate and styles ( Figs. 6E–F , 11E–F ); styles elongated, laterally flattened and curved ( Figs. 3K , 8K ), rendering a unique aspect to this katydid among Microcentrini genera. Tympanum partially closed ( Figs. 3F – 8F ). Internal male genitalia with apodemes sclerites long, narrow sclerites, curved and protruding above ejaculatory vesicles ( Figs. 6A–D , 11A–D ). Redescription . Head dorsally rounded and frontally flat, in lateral view ( Figs. 3D , 8D ). Frons, clypeus and labrum smooth in frontal view ( Figs. 3B , 8D ). Compound eyes globular ( Figs. 3B–C , 8B–C ). Fastigium-vertex short and conic in frontal view ( Figs. 3B , 8B ). Pronotal disc rectangular, without carina, with small bristles, anteriorly slightly concave, laterally straight, and posteriorly convex, in dorsal view ( Figs. 3B–C , 8B–C ). Pronotal disc without spots ( Figs. 3C–D , 8C–D ). Dorsolateral suture sinuose ( Figs. 3C–D , 8C–D ). Dorsolateral and furcal sutures light brown ( Fig. 3C–D , 8C–D ). Lateral lobe of pronotum anteriorly straight and posteriorly convex ( Figs. 3D , 8D ). Mesobasisternum triangular, anteriorly straight ( Figs. 3E , 8E ). Tegmina elongated ( Figs. 4 , 9 ). Vein R with straight branches, parallel and with several small bifurcations; vein CuA with several bifurcated branches; vein MP with two bifurcated branches reaching wing margin ( Figs. 4 , 9 ). Left stridulatory file convex ( Figs. 5A , 10A ). Right stridulatory file sinuous, convex at base and median region, distally concave ( Figs. 5B , 10B ). Teeth from both rows short, narrow and very close to each other; basal teeth and apical teeth smaller and gradually increasing in length towards median region ( Figs. 5A–B , 10A–B ). Tympanum partially closed ( Figs. 3F – 8F ). Fore femur straight, with three ventral spines ( Figs. 3F – 8F ). Fore tibia with five ventral spines ( Figs. 3F – 8F ). Mid femur straight with two ventral spines ( Figs. 3G – 8G ). Mid tibia straight, with basal region slightly expanded, two dorsal spines and twelve ventral spines ( Figs. 3G – 8G ). Hind femur straight, with expanded base and with small black ventral spines ( Figs. 3H – 8H ). Hind tibia slightly curved, ventral margin medially with numerous small thick and curved spines ( Figs. 3H – 8H ). Apex of cercus expanded, with an inward laminar projection with a row of small black triangular teeth ( Figs. 3I–J , 8I–J ). Subgenital plate small, with apex bifurcated between base of stylus, with convex recess in ventral view ( Figs. 3I – 8I ). Styles elongated, laterally flattened and curved ( Figs. 3K , 8K ). Internal male genitalia with large titillator a double hook-shaped sclerite, which protrudes out of the abdomen and is enveloped by the subgenital plate and styles ( Figs. 6E–F , 11E–F ). Ejaculatory vesicle reniform with short ejaculatory ducts ( Figs. 6A–D , 11A–D ). Dorsal lobes curved, posteriorly rounded ( Figs. 6A–D , 11A–D ). Apodemes sclerites long, narrow sclerites, curved and protruding above ejaculatory vesicles ( Figs. 6A–D , 11A–D ). Titillator process elongated and asymmetrical ( Figs. 6C–D , 11C–D ). Dorsal fold short, wide and with rounded apex ( Figs. 6C–D , 11C–D ). Upper folds of ventral lobe wide, with rounded apex ( Figs. 6A–B , 11A–B ). Distribution. Brazil (new record) and Peru ( Fig. 13 ). Included species. Raggophyllum spinosum ( type species). Raggophyllum rubrofemoratum sp. nov. Key to males of Raggophyllum ( Fig. 2 ) Comments . Raggophyllum species distribution is restricted to Inambari, the second larger Amazonian area of endemism, comprising 1.327.00 km², limited to the north by the Amazon river, to the south by the Madeira river and southwest by the Andes mountain range ( Da Silva et al ., 2005 ) ( Fig. 13 ). Information on invertebrate groups associated with this area is scarce. Thus, this is the first study that associates a group of katydids with this region.
