Cyclaxyridae are a family of beetles in the superfamily Cucujoidea. The only living genus is Cyclaxyra, with two species endemic to New Zealand. Other species have been named from fossils. They are also known as sooty mould beetles due to the association of Cyclaxyra with sooty mould. The extant species are mycophagous, feeding on spores, conidia, and hyphae.
