Eupholus petitii is a disputed species of beetle belonging to the family Curculionidae.
Eupholus petitii is now considered by some authors a subspecies of Eupholus schoenherri.
The species name schoenherri honours the Swedish entomologist Carl Johan Schönherr.
This species can be found in New Guinea
Eupholus (schoenherri) petiti is usually metallic bright blue-green, with four transverse unequally spaced black shining bands on elytra. The last band is strongly arched. Antennae are club-shaped, it has a longitudinal groove on the vertex and the extremity of thighs is blue. The blue-green colour derives from very small scales, covering all over the elytra.
