In zoological taxonomy, the names of specific ranks are standardized by convention and international codes to ensure consistency. The following endings are used for these groups:

Superfamily: -oidea
Family: -idae
Subfamily: -inae
Tribe: -ini

These standardized suffixes help biologists identify the rank of a taxon within the animal kingdom. While these rules provide stability for these specific levels, other higher-ranking groups often lack such standardized endings and must be memorized based on their individual taxonomic history.1
