Redescription. Male. Thorax . Mesobasisternum triangular, anteriorly straight; lateral lobes anterolaterally convex, laterally and posteriorly straight, forming a posterolateral blunt tip ( Fig. 134E ). Metabasisternum triangular, anteriorly straight with two small convex lateral protuberances; lateral lobes anterolaterally convex, laterally straight and posteriorly slightly convex, posterolaterally forming an angle of 90° ( Fig. 134E ). Wings. Vein MA with six main branches reaching wing margin ( Fig. 135 ). Tegmina with six narrow and well-defined hyaline bands, overlapping the branches of the M and CuA veins; hyaline bands with small circular patches lined up ( Fig. 135 ). Left stridulatory file curved; apical teeth small ( Fig. 136A ). Total file length of 3.5 mm, greater vein width of 0.5 mm and a total of 52 teeth. Rigth stridulatory file curved; middle and basal teeth large and spaced ( Fig. 136B ). Total length file of 3.1 mm, widest vein of 0.2 mm and total of 59 teeth. Legs . All femora ventrally with several small spines ( Fig. 134H ). Abdomen . Cercus curved inwards, with the apex not expanded ( Figs. 134I–K ).
