Material examined. (2♂ Specimens) India (Kerala, Tamil Nadu): 21.i.2014, Coll. Rajendra Nagar (Thiruvananthapram); 22.ii.2014, Coll. Rajendra Nagar ( TNAU, Coimbatore).

Description. Fastigium verticis narrow, deeply furrowed, apex sub-acute; step-like declined to fastigium frontis. Pronotum with a distinct humeral sinus; anterior coxa without spine, though in some species a minute spinule may be present; Genicular lobes bi-spinose in all legs. Anterior femur curved; on ventral side furrowed, provided with small spines; anterior tibia dorsally furrowed with spines and dorso-apical spurs; tibial tympana covered with conchate fold with wider anterior slit on both sides or on the internal side only; tegmina fully developed, hind wings surpassing tegmina in both sexes; male sub-genital plate without styli.

Male: Pronotum dorsal view with broad V-shaped transverse sulcus; posterior margin rounded; paranota about as high as long, lateral margin rounded. Greatest width of tegmina wider than length of pronotum; radius sector branching about in middle of tegnima, rarely before middle. Stridulatory file on underside of left tegmina with ca 85 teeth; anterior part of file with the teeth larger, widely spaced; in the middle part teeth are small and spaced moderately; whereas, in the posterior part, teeth are closely spaced and smaller. Cerci strongly curved with acute apices. Sub-genital plate split into two lobes for more than apical half.
