The family is based on a monotypic genus, Cheiropleuria, of montane areas in east Asia. The spores are trilete, essentially plain with a prominent flange near the aperture. The exospore is composed of three layers, the middle one extending between the aperture and flange. The perispore is thin and usually plain or slightly rugulate.
