Epifamily

An epifamily is a rank between a superfamily and a family. Epifamilies usually end in -oidae. The ranks of epifamily, infrafamily and infratribe (in animals) are used where the complexities of phyletic branching require finer-than-usual distinctions. Although they fall below the rank of superfamily, they are not regulated under the International Code of Zoological Nomenclature and hence do not have formal standard endings. The suffixes listed here are regular, but informal.

Examples

 * Icteroidae is an epifamily in the Passeroidea superfamily.
 * Termitoidae is an epifamily in the Blattodea order.
