Subgenital plate small, with apex bifurcated between base of stylus, with convex recess in ventral view ( Figs. 3I View FIGURE 3 – 8I View FIGURE 8 ). Styles elongated, laterally flattened and curved ( Figs. 3K View FIGURE 3 , 8K View FIGURE 8 ). 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 View FIGURE 6 , 11E–F View FIGURE 11 ). Ejaculatory vesicle reniform with short ejaculatory ducts ( Figs. 6A–D View FIGURE 6 , 11A–D View FIGURE 11 ). Dorsal lobes curved, posteriorly rounded ( Figs. 6A–D View FIGURE 6 , 11A–D View FIGURE 11 ). Apodemes sclerites long, narrow sclerites, curved and protruding above ejaculatory vesicles ( Figs. 6A–D View FIGURE 6 , 11A–D View FIGURE 11 ). Titillator process elongated and asymmetrical ( Figs. 6C–D View FIGURE 6 , 11C–D View FIGURE 11 ). Dorsal fold short, wide and with rounded apex ( Figs. 6C–D View FIGURE 6 , 11C–D View FIGURE 11 ). Upper folds of ventral lobe wide, with rounded apex ( Figs. 6A–B View FIGURE 6 , 11A–B View FIGURE 11 ).

Distribution. Brazil (new record) and Peru ( Fig. 13 View FIGURE 13 ).

Included species.

Raggophyllum spinosum (type species).

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 View FIGURE 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.
