We describe a morphologically remarkable new species of the Epicauta cupraeola species group from the highlands of the State of Nayarit, Mexico. The external appearance of Epicauta cora sp. nov., is similar to that of Epicauta rufipennis and Epicauta diana, but it is distinct from both species based on male antennae structure, shape and pilosity of the head and pronotum, color of pronotal pilosity, and male fore-tarsal structure. The nine species integrating now the E. cupraeola species group have been revised. This study of 323 specimens, including diverse type material, confirms the synonymy of Cantharis rufescens with Epicauta basimacula first proposed by Pinto (1991), and reports new geographic records for Mexican taxa. The species of the E. cupraeola group are included in a key and illustrated photographically, including type specimens of five taxa. A phylogenetic re-analysis of the E. cupraeola species group results in the placement of the new species as sister to E. rufipennis, which together form a sister clade to the remaining species of the E. cupraeola group.
