Green to ochraceous. Spot at base of forewing appendix piceous.
Head slightly longer medially than next to eyes. Disc of vertex slightly depressed. Face rather flat, with upper margin transversely striated. Clypellus strongly broadened apicad, with median ridge in basal half. Ocellus situated on front margin of crown next to corresponding eye, separated from eye by distance equal to ocellus diameter. Pronotum more than 3 times as long as head, slightly wider than long, scutellum as long as pronotum. Male eighth sternite with hind margin slightly concave.

(Fujian, Zhejiang, Guangdong, Hainan).
Remarks:
This species is peculiar and can be distinguished by the shape of the aedeagus, with the preatrium well developed, a basal triangular process and many tiny teeth.
Etymology:
The new species is named after Prof. Dr. C. A. Viraktamath, University of Agricultural Sciences, Bangalore,
India
, in recognition of his work on leafhoppers.
