Holotype (male): Indonesia: West Sumatra, Fort de Kock [Bukittinggi], [0°15'S, 100°23'E], 920 m, 1.i.– 31.xii.1924, leg. E. Jacobson ( RMNH).

Material studied: 1 male, Indonesia: Sumatra, " Elimaea sp.n. vicina: roseae Br.", " Type Brunn." ( MHNG).

Diagnosis. The species is unique for the stridulatory area with acute process on the left and rounded process on the right tegmen, and for the short male cerci with the huge compressed towards apex acute apical tooth.

Description. Fastigium verticis slightly declining and constricted in circa middle of length, anterior half narrow, shallowly furrowed on dorsal surface; step-like descending to fastigium frontis. Pronotum long and narrow, posterior margin rounded; paranota nearly twice as long as high, ventral margin slightly convex, humeral sinus distinct.

Male. Stridulatory area of left tegmen with inner margin angularly projecting ( Fig. 2 View FIGURE 2 L), on right tegmen roundly projecting forming a small "secondary mirror"; mirror proper nearly circular ( Fig. 2 View FIGURE 2 M). Stridulatory file on underside of left tegmen sinuate, carrying 39–45 teeth: about 18–19 teeth from base medium sized, thereafter becoming gradually narrower and smaller towards apex ( Fig. 3 View FIGURE 3 A). Cerci short, curved, at apex with a large, compressed, at tip acute tooth ( Fig. 4 View FIGURE 4 P–Q). Subgenital plate with basal quarter rather wide, thereafter strongly narrowed into a long process that is narrowing to behind middle and moderately widening again towards apex; less than apical quarter divided into two lobes with finely spinulose internal margins ( Fig. 5 View FIGURE 5 D). Phallus with a pair of conchate semi-hyaline sclerites with stiffened, brown, denticulate margin ( Fig. 6 View FIGURE 6 K–L).

Female unknown.

Measurements (1 male). Body w/o wings: 20; pronotum: 4.7; tegmen: 29; tegmen width: 3.3; hind femur: 22 mm (after Karny 1926a).

Etymology. Named for the white stridulatory area of male tegmen.
