Redescription. Male. Stridulatory area of left tegmen roughly triangular, 2.98 mm long, 1.81 mm wide ( Fig. 9 C); stridulatory file on underside of left tegmen concave and slightly curved, 1.58 mm long; teeth slightly dense in basal quarter; with about 132 teeth ( Figs. 3 D, 11B); mirror roughly oval, 3.15 mm long, 1.85 mm wide ( Fig. 9 D).
