Redescription. Male. Stridulatory area of left tegmen roughly triangular, 3.24 mm long, 1.85 mm wide ( Fig. 9 G); stridulatory file on underside of left tegmen concave and slightly sinuate, 1.59 mm long; teeth faint and slightly dense in basal fifth; with 120–130 teeth ( Figs. 4 C, 11K); mirror roughly oval, 3.25 mm long, 1.98 mm wide ( Fig. 9 H). Cerci long, surpassing apex of subgenital plate ( Fig. 5 J); baso-interal side expanded; moderately curved inwards; apex with a wide, slightly curved, sclerotized tooth. Phallus with two pairs of complex sclerites: lateral sclerites slightly wide, denticulate apex curved inwards; medial sclerites divided into dorsal and ventral lobes, both lobes widely spaced, dorsal lobe with apical margin denticulate. Subgenital plate curved dorsally before middle; lateral carinae distinct on ventral surface; basal part broad, medial area equal width with apical part, apico-lateral margins parallel, posterior margin excised widely, bottom of excision nearly straight, apico-lateral projections narrow ( Fig. 5 K).
