Diagnosis. Tegmina with an pentagonal cell present between veins MP and CuA ( Fig. 8 View FIGURE 8 ). Cercus apex rounded, with a hook-like spine ( Fig. 7K View FIGURE 7 ). Lateral lobes of mesosternum triangular, narrowed, parallel, with rhomboid apex Description. Male.

Head. Rugose. Fastigium dorsally short, gently bilobed. Vertex trapezoidal, frontally bilobed.

Thorax. Dorsal pronotal disc rugose with slight linear depression ( Figs. 7 View FIGURE 7 C–D). Dorsolateral and furcal sutures deeply marked ( Fig. 7C View FIGURE 7 ). Furcal sutures connected. Meso- and metasternum laterally compressed ( Fig. 7C View FIGURE 7 ). Mesosternum anteriorly rhomboid. Lateral lobes of mesosternum with apex rhomboid ( Fig. 7E View FIGURE 7 ). Metasternum diamondshaped ( Fig. 7E View FIGURE 7 ). Lateral lobes of metasternum curved with rounded apex ( Fig. 7E View FIGURE 7 ).

Wings. A pentagonal cell present between veins MP and CuA ( Fig. 8 View FIGURE 8 ). Vein CuA with five bifid branches with bifurcations at apex ( Fig. 8 View FIGURE 8 ). Left stridulatory with basal teeth short, gradually increasing in length towards median region ( Fig. 9A View FIGURE 9 ). Median teeth slender, close to each other. Left stridulatory file with 78 teeth, length of 3.2 mm and greatest width of the vein of 0.4 mm ( Fig. 9A View FIGURE 9 ). Left stridulatory sinuous, with convex base, median region nearly straight, distally concave ( Fig. 9B View FIGURE 9 ). Basal and distal teeth short, widened. Median teeth slender, close to each other ( Fig. 9A View FIGURE 9 ). Right stridulatory file with 67 teeth, length of 2.3 mm and greatest width of the vein of 0.1 mm ( Fig. 9B View FIGURE 9 ).

Legs. Mid tibia slightly widened basally, with three ventral spines ( Fig. 7G View FIGURE 7 ). Hind femur with six ventral spines, wider basally ( Fig. 7H View FIGURE 7 ).

Abdomen. Cercus inward curved; apex rounded with small hook-shaped spine ( Fig. 7H View FIGURE 7 ). Subgenital plate trapezoidal, with length not reaching half of cerci length ( Fig. 7I View FIGURE 7 ). Apex of subgenital plate inconspicuously emarginated ( Figs. 7 View FIGURE 7 I–J). Stylus rectangular and short ( Figs. 7 View FIGURE 7 I–J). Cercus and subgenital plate covered with numerous bristles ( Figs. 7 View FIGURE 7 I–K).

Internal male genitalia. Not examined.

Coloration. Based on photos of preserved specimen ( Fig. 7 View FIGURE 7 ). Generally yellowish-brown, with some light green tegmina parts. Compound eyes brown. Sternites, cercus, subgenital plate and stylus yellow.

Female. Unknown.

Etymology. The species is named after the Solimões river, the main river in the species locality.
