Pronotum slightly longer than head and distinctly shorter than mesonotum excluding cruciform elevation. Lateral pronotal collar dentate. Mesonotum greenish or ochraceous with black marks. Wings hyaline, with eight and six apical cells on fore wing and hind wing, respectively. Fore wing with apical cells in short length. Fore wing with infuscations on radial and radiomedial crossveins. Male operculum short and comparatively narrow, longer than wide, extending slightly beyond posterior margin of abdominal sternite II. Male opercula widely separated. Male abdomen about as long as head and thorax together. Male abdominal tergite 3 wider than mesonotum. Timbal cover widely open dorsally. Male pygofer obovate in ventral view. Clasper and upper lobes of pygofer absent. Uncus thick and short, with uncal lobes fused at base, bifurcate distally; curved inwardly in lateral view.
