Length of male 7.1–7.5 mm, female 8.7 mm. Crown anterior margin, lateral margin of pronotum and costal margin of forewing bordered with pale yellow contrasting with darker adjacent areas; dorsal margin of face and dorsal surface of front tibia dark brown, other legs without dark markings. Crown distinctly shorter than pronotum, broadly rounded, only slightly longer medially than next to eye, anterior margin broadly rounded. Hind tibial rows PD, AD and AV with 19, 12 and 10 macrosetae, respectively. Male pygofer without ventral process. Style apophysis with dense patch of denticuli preapically on ventrolateral surface; aedeagal shaft with gonopore-bearing apical process very short and ventral branch also shorter and strongly asymmetrical, unpaired ventral process surpassing shaft and strongly hooked apically.Aedeagus with atrium disc-like, shaft arising dorsally with short, stout recurved process bearing gonopore and longer falcate process with excavated anteroventral surface curved ventrad; unpaired long, slender, slightly asymmetrical process arising ventrally from atrium and curved dorsad. Female abdominal sternite VII with pair of short, narrow median lobes.
