Utilising phylogenetic estimates inferred from molecular sequences, the superfamily Lepocreadioidea Odhner, 1905 is re-organised, with the major family, the Lepocreadiidae, split into three separate families, the Lepocreadiidae Odhner, 1905, Aephnidiogenidae Yamaguti, 1934 and Lepidapedidae Yamaguti, 1958. These families have been widely recognised as subfamilies. Also recognised are the families Enenteridae Yamaguti, 1958, Gorgocephalidae Manter, 1966 and Gyliauchenidae Fukui, 1929. The constituent genera of these families are listed, some relying on molecular data and others on morphological similarity to molecularly-typed genera. Nine genera have not been placed in families and are considered incertae sedis
