Four new species of Buprestidae from Mexico are described and figured. They are Acmaeodera chamelensis sp. nov., A. rodriguezae sp. nov. and Mastogenius aliciae sp. nov. from Jalisco, and M. cyanelytra sp. nov. from the state of Mexico.

Se describen e ilustran cuatro nuevas especies de Buprestidae de México. Las especies son: Acmaeodera chamelensis sp. nov., A. rodriguezae sp. nov. y Mastogenius aliciae sp. nov. de Jalisco, y M. cyanelytra sp. nov. del Estado de México.
