Historically, these beetles were placed in a superfamily "Cantharoidea", which has been subsumed by the superfamily Elateroidea; the name is still sometimes used as a rankless grouping, including the families Cantharidae, Drilidae, Lampyridae, Lycidae, Omalisidae, Omethidae, Phengodidae (which includes Telegeusidae), and Rhagophthalmidae.
