Redescription. Male. Stridulatory area of left tegmen oval, 3.25 mm long, 1.77 mm wide ( Fig. 10 E); stridulatory file on underside of left tegmen concave and slightly curved, 1.56 mm long; teeth faint in basal fifth; with 135–146 teeth ( Figs. 4 D, 11A); mirror long oval, 3.16 mm long, 1.8 mm wide ( Fig. 10 F). Tenth abdominal tergite with posterior margin concave; epiproct small, tongue-shaped; cerci long, but not reaching apex of subgenital plate ( Fig. 6 J); baso-internal side expanded; in apical one - third curved inwards rectangularly, then curled upwards; apex with a wide, slightly curved, sclerotized tooth ( Fig. 6 L). Phallus with two pairs of sclerites: lateral sclerites narrowly sheet-shaped, apical half curled longitudinally, top denticulate; medial sclerites much small, apex divided into dorsal lobe denticulate and wider ventral lobe. Subgenital plate curved dorsally before middle; lateral carinae distinct on ventral surface; basal part broad, medial area narrow and apical part widened, posterior margin longitudinally split into two wide lobes ( Fig. 6 K).
