Figures 142–146
Diagnosis. Vein MA with three main branches reaching wing margin (Fig. 143). Mesobasisternum anteriorly straight; lateral lobes anterolaterally convex, laterally straight, posteriorly slightly concave, forming a posterolateral blunt tip (Fig. 142E). Metabasisternum anteriorly convex; lateral lobes anterolaterally convex, laterally straight and posteriorly convex, posterolaterally forming an angle of 90° (Fig. 142E). Left stridulatory file curved with total of 48 teeth; apical teeth small and gradually smaller towards the apex; apical teeth large (Fig. 144C).
Description. Holotype Male.
Thorax. Mesobasisternum triangular, anteriorly straight; lateral lobes anterolaterally convex, laterally straight, posteriorly slightly concave, forming a posterolateral blunt tip (Fig. 142E). Metabasisternum triangular, anteriorly convex; lateral lobes anterolaterally convex, laterally straight and posteriorly convex, posterolaterally forming an angle of 90° (Fig. 142E).
Wings. Vein MA with three main branches reaching wing margin (Fig. 143). Tegmina with six asymmetric hyaline bands with wide and narrow regions, overlapping the branches of the M and CuA veins (Fig. 143). Hyaline bands medially with asymmetric white spots with dark green circular spots and apically asymmetric black spots (Fig. 143). Left stridulatory file curved; apical teeth small and gradually smaller towards the apex (Fig. 144A). 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). 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).
Abdomen. Cercus curved inwards, with the apex not expanded (Figs. 142I–K). Apex of cercus with curved convex projection and lateral spine, with a dark brown color (Fig. 142K). Stylus large and fusiform (Fig. 142I).
Internal male genitalia. Ejaculatory vesicles reniform (Figs. 145A–D). Upper folds of ventral lobe large, trapeziodal and connected (Figs. 145A–B). Titillator process large and asymmetrical (Figs. 145A–D). Lower folds of ventral lobe large, trapeziodal and posteriorly convex (Figs. 145A–B). Dorsal lobes anteriorly with median triangular projection, laterally and posteriorly convex (Figs. 145A–D). Dorsal folds elongated and asymmetrical (Figs. 145C–D).
Coloration. Based on photos of preserved specimen (Fig. 142). Body yellowish-brown. Eyes brown.
Female: Unknown.
Etymology. This species is dedicated to the Orthopterologist and friend Oscar Cadena-Castañeda.
Distribution. Costa Rica: Alajuela (Fig. 146).

Species-group Tropicophyllum mirim Mendes & Rafael sp. nov.
Figures 147–162
Coments. Group formed by three species of the Amazon rainforest biome (Figs. 147, 154, 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). In addition, they are differentiated by elongated tegmina (Figs. 148, 155, 159); vein MA with five main branches reaching wing margin (Figs. 148, 155, 159); tegmina with six large asymmetric hyaline bands (Figs. 148, 155, 159). Posterior region of tegmina with several small black spots (Figs. 148, 155, 159); vein MP and last branch of CuA vein forming a large pentagonal cell (Figs. 148, 155, 159); all femora ventrally with several small spines (Figs. 147F–H, 154F–H, 158F–H).
