The Hybosoridae is considered as a family within the Scarabaeoidea. The family Hybosoridae includes 32 genera and 220 species. This is a cosmopolitan family, which is best represented in the tropics.
Results of phylogenetic analyses of the family Hybosoridae based on 120 morphological characters and DNA 28S D2 and D3 regions are presented. According to the phylogenetic analyses the family Ocahodaeidae is the sister group of Hybosoridae. The family Hybosoridae is a paraphyletic group and includes the family Ceratocanthidae. Two new subfamilies were described and are presented here: Liparochrinae (Hybosoridae) and Pachyplectrinae (Hybosoridae). A new classification scheme is presented. The Neotropical tribe Anaidini is revised and phylogenetic and historical biogeographic analyses of the tribe are presented.
