Decelle, 1972

Peltophorus is a of in the ( Baridinae, tribe Zygopini). The genus contains multiple distributed in Mexico, including P. polymitus and P. adustus. Species in this genus are associated with succulent plants, particularly agaves and cacti. P. polymitus has been documented feeding on at least seven Agave species and has been recorded in wild agave plantations, though it has not been formally designated as an agricultural pest.
