Description. Head ovoid, occiput convex and smooth. Fastigium verticis well-produced, dorsally sulcate, distinctly narrower than first segment of antenna, with apex approximately rounded. Fastigium frontis inversely ovoid; dorsal apex slightly narrower than fastigium verticis, separated by a distinct gap. Compound eyes semi-spherical, ventral margin extending over ventral margin of antennal scrobe. Antenna thread-like, long and breakable. Pronotal disc smooth, with distinct longitudinal median line; median groove distinct, “U”- shaped, lying before middle; anterior margin approximately straight, posterior margin rounded and various, lateral margin outspreading backwards; paranota generally deeper than long, rarely as high as long; humeral sinus distinct. Anterior coxae armed. Each femur with distinct ventro-anterior spinules. Anterior tibiae dorsally sulcate, widened at and abruptly constricted below tympana. Outer tympanum open, oval, membranous; inner tympanum conchate. Each tibia usually with dorsal spinules on both margins. Tegmen well developed, stridulatory file on underside of left tegmen not elevated above wing plane ( Figs. 1–9 ); mirror of right tegmen irregular quadrangular ( Figs. 10–18 , 20). Male terminalia ( Figs. 31–47 ). Tenth abdominal tergum normal, slightly concave in middle. Epiproct triangular, with apex obtuse. Cerci simple, apex pointed or not ( Figs. 49–57 ). Subgenital plate robust, with emargination at the apex; with styli ( Figs. 58–66 ). Male phallic organ membranous. Female terminalia ( Figs. 67–74 ). Tenth abdominal tergum not produced, with dorso-medial groove; posterior margin obtusely emarginated. Epiproct usually wider than long, about semicircular. Cerci short, slightly curved, uneven; gradually tapering into pointed apex. Subgenital plate generally triangular (Figs. 75– 82). Ovipositor robust, wide; lateral surface with very conspicuous transverse convex fold at base; with some sharp dark serrate lines in distal region; both margins serrate ( Figs. 67–74 ).

Diagnosis. Each femoral genicular lobe round, without any spines; tegmen without distinct Costa vein; male tympanal area with two very much swollen diagonal veins, the posterior one about one-half as long as the anterior one; male stridulatory vein cambered, simple, with dense fine teeth ( Figs. 21–30 ); male tenth abdominal tergum not produced ( Figs. 31–47 ); male subgenital plate with short styli ( Figs. 58–66 ); female ovipositor with an abrupt sharp tip, rugose on the sides and both apical margins ( Figs. 67–74 ).
