Cucujoidea is a superfamily of beetles. This group formerly included all of the families now included in the superfamily Coccinelloidea.[1] They include some fungus beetles and a diversity of lineages of "bark beetles" unrelated to the "true" bark beetles (Scolytinae), which are weevils (superfamily Curculionoidea).

## Morphology

The morphology of Cucujoidea is varied and there are no features uniting all members of the superfamily.[1]

Adults can be recognised by the procoxal cavities being internally open in most taxa, females having tarsal formula 5-5-5 and males 5-5-5 or 5-5-4 (rarely 4-4-4), females with tergite VIII concealed dorsally by tergite VII, and males with tergite X completely membraneous.[1]

Larvae have frontal arms usually lyriform, the mandible mesal surface usually with well-developed mola, a maxillary articulating area usually present, a hypopharyngeal sclerome usually present, and two pretarsal setae.[1]
