Diagnosis.

This species is distinguished by the acute end of anal segment process, suspensorium with dorsal part Y-shaped stubby, phallus strongly compressed laterally with large plate-like process turning left dorsomedially, diaphragm with moderate and plate-like process at each side of dorsal margin.

Description.

Macropterous: Body length (from apex of vertex to the tip of forewing): male 4.76 mm, female 5.56 mm; forewing length: male 4.24 mm, female 4.66 mm.

Coloration: General color pale yellowish brown to dirty yellowish brown. Vertex with outer area to submedian carinae black brown, frons with narrow stripe, brown, genae yellowish brown. Ocelli dark. Eyesdark brown to black. Dorsum of abdomen brown.

Structure: Head including eyesnarrower than pronotum (0.79:1), Vertex longer submedially than wide at base about 1.3:1, as wide at apex as at base, apical margin transverse, lateral margins of vertex in dorsal view subparallel, submedian carinae originating from near 1/4 base of lateralcarinae, not uniting at apex, basal compartment wider at base than greatestlength. Frons longer in middle line than wide at widest part about 2.2:1, widest at level of ocelli, lateral carinae straight, median carina forked at base. Postclypeus large, as wide at base as frons at apex. Rostrum reaching to mesochanters. Antennae cylindrical, reaching slightly beyond frontoclypeal suture, basal segment longer than wide about 1.4:1, shorter than second about 1:2.5. Lateral carinae of pronotum curved. Post-tibial spur with about 20-23 teeth. Tegmina longer than widest part about 3.5:1, rounded at apex.

Male genitalia: Anal segment of male large, with a stout, twist median spinose process which pointing to the right apically, with a small process in ventral margins each side. Pygofer in profile distinctly wider ventrally than dorsally, laterodorsal angle not produced, in posterior view with opening longer than wide. Phallus strongly compressed laterally with large plate-like process turning left dorsomedially, which gradually tapering to apex. Suspensorium with the dorsal portion Y-shaped and stubby. Diaphragm broad, dorsomedially with a large process, with a pair small plate-shaped projection at each side. Opening for genital styles, with a small process at dorsal margin medially, with curved at ventral margin. Genital styles long and slender, narrowed near apex, evenly convex laterad medially.
