From Kundrata et al., 2020: The monotypic Elaterina Gardiner, 1961 from the Jurassic of the United Kingdom was originally placed in Elateridae, but Whalley  questioned that placement because the holotype elytron of E. liassica Gardiner, 1961 shows none of the diagnostic characters of Elateridae. Carpenter  classified it in Coleoptera incertae sedis.
