Ommatidae
Family of beetles
From Wikipedia, the free encyclopedia
The Ommatidae are a family of beetles in the suborder Archostemata.[1] The Ommatidae are considered the extant beetle family that has most ancestral characteristics.[2] There are only seven extant species, confined to Australia and South America. However, the geographical distribution was much wider during the Mesozoic spanning across Eurasia, South America,[3] and Australia, suggesting that they were widespread on Pangea.[4] So far, over 26 extinct genera containing over 170 species of these beetles have been described.[5] Three extant genera have been assigned to this family: Omma, Tetraphalerus and Beutelius.[6] The family is considered to be a subfamily of Cupedidae by some authors,[7] but have been found to be more closely related to Micromalthidae in molecular phylogenies.[8] A close relationship with Micromalthidae is supported by several morphological characters, including those of the mandibles and male genitalia.[9] Due to their rarity, their ecology is obscure, it is likely that their larvae feed on deadwood.[10]
