Description. Medium sized species; fastigium verticis slender; dorsally furrowed, separated from fastigium frontis by a large gap; pronotum ( Fig.7 ) with a fine median carina, the transverse sulcus beyond middle V-shaped or short Y-shaped; humeral sinus distinct; paranota with rounded ventral margins; tegmina with costal field widened in basal third; dorsal field dilated for1/ 2.3 of tegminal length; margin sub-parallel behind the dilation; tegmina surpassing hind knee; radius sector branching between 11.50–13.50 mm from the base of tegmina.

Male. Stridulatory file ( Fig.10 ) with a break shortly before posterior end, ca. 135–145 teeth; anterior coxae with a small spine and femora dorsally rounded, straight, and of equal width over the whole length; internal and external tympana open ( Fig.5 ) and conchate; tenth tergite large, apex slightly concave; supra anal plates subquadrate, apex slightly excised in middle, apical angles rounded, a shallow medial impression at base; cerci securiform ( Fig.9 ), sub-genital plate behind basal fourth part suddenly narrowed and divided into two sub-parallel lobes, external apex of lobes sub-acute ( Fig.8 ); median area of both lobes densely covered by small, strong spinules.

Female. Tenth abdominal tergite with apex sub-truncate and notched; epiproct curved upwards, apex broadly sub-truncate; cerci regularly curved, apex acute ( Fig.1 ); sub-genital plate sub-truncate, faintly furrowed, apex rounded ( Fig.2 ); gonangulum ( Fig.3 ) of ovipositor with a short obtuse ventral projection; ovipositor falcate with valves upturned and serrate ( Fig.4 ).
