Antennal scape shaped as round shield. Genae slightly convex. Labrum apical margin broadly concave. Terminal maxillary palpus bevelled apically, almost equal to length of 3rd palpus; terminal labial palpus rod-like, almost equal to total length of remaining palpi. Pronotum trapezoidal, disc flattened and broad, anterior margin weakly concave, posterior margin slightly convex ( Fig. 3A View FIGURE 3 ). Harp area bearing 5 harp veins. False veins distributed in harp field and mirror. Forewing dorsum broad ( Fig. 3A View FIGURE 3 ). Apical field of elytra armed with 7 branches ( Fig. 3A View FIGURE 3 ). Exposed part of hind wings slightly shorter than hind tarsus ( Fig. 3A View FIGURE 3 ). External tympanum large and shaped as elongate-ovoid. Hind tarsus armed with dorsal spines, numbered 9:9 for inner and outer.

In lateral view, epiphallic apex slightly expanded, angled at distal margin and armed with small denticles ( Fig. 3F View FIGURE 3 ); in dorsal view, epiphallic apex possessing obtuse angle at inner margin and outside widely concave ( Fig. 3E View FIGURE 3 ).

Female. Similar to male ( Fig. 3B View FIGURE 3 ). Ovipositor very longer than hind tibia; its apex of rather acute and episternites blunt ( Figs. 13B View FIGURE 13 , 14B View FIGURE 14 ).
