Tegmen deep brown at apex, and with black spot and strips, black spot near basal margin of 2nd apical cell, black strips along cross veins of costal cell, and a shorter stripe within 4th apical cell. | | Head： | Head elongate, the lateral sides parallel for a distance in front of eyes and then converging to apex; the median coronal suture through vertex prominently; the lateral margin suture from base to ocelli weakly; ocelli lie at apical three-fifths; ocelli nearer to each other than distance between ocular; vertex in middle line 1.03-1.1 times in male and 1.17-1.31 times in female longer than wide of anteocular; the median length of vertex 1.15-1.22 times in male and 1.43-1.62 times in female longer than pronotum. | | Thorax： | Pronotum broad, 0.58-1.62 times in female longer than pronotum; pronotum broad, 0.58-0.63 times in male and 0.54-0.60 in female longer than wide, the lateral side slightly converging to rounding apex, the later posterior side convex, and the posterior side concave; scutellum width 1.28-1.42 times in male and 1.32-1.44 times in female wider than length. | | Tegmina： | 1st apical cell 3.1 times longer than widest part; 2nd apical cell base broader than apex; 3rd apical cell narrow, base narrower than apex; 4th apical cell outer side broader than inner side. | | Measurements： | Body length (excluding tegmen): 4.68-5.25 mm in male, 5.41-5.86 mm in female.
Tegmen length: 4.03-4.46 mm in male, 4.76-5.22 mm in female. | | Description╱Male | | Genitalia： | Pygofer with a pair of process which near dorsocaudal margin, inner side, directed ventrad, with many macrosetae in dorsal and lateral side; plate length 7.43 times longer than width at middle, and blunt at apex, with many long setae apex and lateral margin; style acute at apex and at base, concave at apical third and at half; aedeagus in lateral view downcurved at apex, with a pair of upcurved process at apical third, and with four stings at apex, the outer ones longer than inner two. | |
