Sphaeritidae

Definition

A small family of beetles (order Coleoptera) containing the single genus Sphaerites, commonly called false clown beetles. The five known species are distributed across temperate regions of the Northern Hemisphere, typically in forested or upland habitats. Though historically grouped with clown beetles (Histeridae) due to convergent rounded body forms, Sphaeritidae are now placed in the superfamily Hydrophiloidea based on larval and adult morphology.

Etymology

Example

Sphaerites glabratus, a widespread Palearctic species, exemplifies the family's characteristic compact, convex body shape and association with decaying fungal fruiting bodies.

Synonyms

• false clown beetles

Related Terms

• Sphaerites
• Coleoptera
• Hydrophiloidea
• Histeridae
• family (taxonomy)
• monotypic family

Usage Notes

The common name 'false clown beetles' reflects historical taxonomic confusion with Histeridae; specialists now emphasize Hydrophiloidea affinities. The family is monotypic at the generic level, making Sphaerites and Sphaeritidae effectively coextensive in practice.
