Scirtoidea is a superfamily of beetles. [1] It is traditionally considered to consist of four families: Clambidae, Decliniidae, Eucinetidae and Scirtidae. [2] However, genetic studies have suggested that Clambidae and Eucinetidae belong to a separate superfamily Clamboidea, which also includes Derodontidae. Scirtoidea and Clamboidea are the two earliest diverging lineages of living polyphagans. [1]
Two extinct families have also been assigned to this group:
- † Mesocinetidae Kirejtshuk and Ponomarenko 2010 Late Jurassic-Early Cretaceous (Asia)
- † Elodophthalmidae Kirejtshuk and Azar 2008 monotypic, Lebanese amber, Barremian
