Syneta is a genus of leaf beetles in the subfamily Synetinae.

[1][2][3][4][5] The genus is entirely holarctic in distribution, with species appearing in North America, Siberia, East Asia and Northern Europe.

[6] The generic name Syneta, derived from the Greek word συνετός meaning "sagacious",[7] was first used by Eschscholtz in his collection, though he never published it.

Syneta was then listed in the last two editions of Dejean's Catalogue of Coleoptera.

No characters for the genus were mentioned in the Catalogue, though three species were listed; of these species, only one (Syneta betulae) was considered valid, the other two being nomina nuda, automatically making it the type species of the genus.
