Redescription. Male. Stridulatory area of left tegmen roughly oval, 2.28 mm long, 1.74 mm wide ( Fig. 9 E); stridulatory file on underside concave and slightly curved; 1.48 mm long; extremely dense in basal third; with 130– 138 teeth ( Figs. 3 K, 11C); mirror oval, 2.98 mm long, 1.85 mm wide ( Fig. 9 F). Male cerci comparatively short, not reaching apex of subgenital plate ( Fig. 6 A); baso-interal side expanded; moderately curved inwards in apical third; apex with heavily sclerotized apical ridge ( Fig. 6 C). Phallus with two pairs of sclerites: lateral sclerites wider and longer, apex with 2 apical spines directed backwards, medial sclerites short with apical notch (dorsal part membranous with few denticles, ventral part without denticles). Subgenital plate curved dorsally before middle; basal part broad, medial area narrow and apical part widened, apex longitudinally split into two wide lobes, posterior margins truncated ( Fig. 6 B).
