Figures 142–146 View FIGURE 142 View FIGURE 143 View FIGURE 144 View FIGURE 145 View FIGURE 146

Diagnosis. Vein MA with three main branches reaching wing margin ( Fig. 143 View FIGURE 143 ). Mesobasisternum anteriorly straight; lateral lobes anterolaterally convex, laterally straight, posteriorly slightly concave, forming a posterolateral blunt tip ( Fig. 142E View FIGURE 142 ). Metabasisternum anteriorly convex; lateral lobes anterolaterally convex, laterally straight and posteriorly convex, posterolaterally forming an angle of 90° ( Fig. 142E View FIGURE 142 ). Left stridulatory file curved with total of 48 teeth; apical teeth small and gradually smaller towards the apex; apical teeth large ( Fig. 144C View FIGURE 144 ).

Description. Holotype Male.

Thorax. Mesobasisternum triangular, anteriorly straight; lateral lobes anterolaterally convex, laterally straight, posteriorly slightly concave, forming a posterolateral blunt tip ( Fig. 142E View FIGURE 142 ). Metabasisternum triangular, anteriorly convex; lateral lobes anterolaterally convex, laterally straight and posteriorly convex, posterolaterally forming an angle of 90° ( Fig. 142E View FIGURE 142 ).

Wings. Vein MA with three main branches reaching wing margin ( Fig. 143 View FIGURE 143 ). Tegmina with six asymmetric hyaline bands with wide and narrow regions, overlapping the branches of the M and CuA veins ( Fig. 143 View FIGURE 143 ). Hyaline bands medially with asymmetric white spots with dark green circular spots and apically asymmetric black spots ( Fig. 143 View FIGURE 143 ). Left stridulatory file curved; apical teeth small and gradually smaller towards the apex ( Fig. 144A View FIGURE 144 ). Total file length of 1.7 mm, greater vein width of 0.5 mm and a total of 48 teeth. Right stridulatory with curved basal half and straight apical half; medium teeth larger and more spaced apart ( Fig. 144B View FIGURE 144 ). Total length file of 1.7 mm, widest vein of 0.1 mm and total of 48 teeth.

Legs. All femora with long triangular ventral spines ( Figs. 142F–H View FIGURE 142 ).

Abdomen. Cercus curved inwards, with the apex not expanded ( Figs. 142I–K View FIGURE 142 ). Apex of cercus with curved convex projection and lateral spine, with a dark brown color ( Fig. 142K View FIGURE 142 ). Stylus large and fusiform ( Fig. 142I View FIGURE 142 ).

Internal male genitalia. Ejaculatory vesicles reniform ( Figs. 145A–D View FIGURE 145 ). Upper folds of ventral lobe large, trapeziodal and connected ( Figs. 145A–B View FIGURE 145 ). Titillator process large and asymmetrical ( Figs. 145A–D View FIGURE 145 ). Lower folds of ventral lobe large, trapeziodal and posteriorly convex ( Figs. 145A–B View FIGURE 145 ). Dorsal lobes anteriorly with median triangular projection, laterally and posteriorly convex ( Figs. 145A–D View FIGURE 145 ). Dorsal folds elongated and asymmetrical ( Figs. 145C–D View FIGURE 145 ).

Coloration. Based on photos of preserved specimen ( Fig. 142 View FIGURE 142 ). Body yellowish-brown. Eyes brown.

Female: Unknown.

Etymology. This species is dedicated to the Orthopterologist and friend Oscar Cadena-Castañeda.

Coments. Group formed by three species of the Amazon rainforest biome ( Figs. 147 View FIGURE 147 , 154 View FIGURE 154 , 158 View FIGURE 158 ). It is the most distinctive and iconic group of species among the Tropicophyllum , as they have a very small size, being equivalent to about half the length of the species of groups T. colloseum and Tropicophyllum sentum ( Fig. 152 View FIGURE 152 ). In addition, they are differentiated by elongated tegmina ( Figs. 148 View FIGURE 148 , 155 View FIGURE 155 , 159 View FIGURE 159 ); vein MA with five main branches reaching wing margin ( Figs. 148 View FIGURE 148 , 155 View FIGURE 155 , 159 View FIGURE 159 ); tegmina with six large asymmetric hyaline bands ( Figs. 148 View FIGURE 148 , 155 View FIGURE 155 , 159 View FIGURE 159 ). Posterior region of tegmina with several small black spots ( Figs. 148 View FIGURE 148 , 155 View FIGURE 155 , 159 View FIGURE 159 ); vein MP and last branch of CuA vein forming a large pentagonal cell ( Figs. 148 View FIGURE 148 , 155 View FIGURE 155 , 159 View FIGURE 159 ); all femora ventrally with several small spines ( Figs. 147F–H View FIGURE 147 , 154F–H View FIGURE 154 , 158F–H View FIGURE 158 ).
