Gergithus is a genus of tropical Asian planthoppers in the family Issidae, erected by Carl Stål in 1870.[1] Like all planthoppers, adults feed on plant sap and are capable of escaping by leaping. The genus like other members in the tribe appears somewhat rounded and beetle-like, in some cases, with a mimetic resemblance to ladybird beetles. Species are mostly distributed in the Indomalayan Realm.

Description
editThe genus is closely related to Hemisphaerius but differs in having longer frons (forehead) and legs. The frons lacks a median keel (carina) or tubercles on the frons, pronotum or mesonotum. The rounded tegmen which resembles the elytra of beetles are often patterned. Although some species show variations in pattern, many species can be recognized on the basis of the patterns.[2]
