Usage notes

At species level or below, a name-bearing type is a physical specimen or illustration (usually the holotype, but it can be a lectotype, neotype or other type). For higher-level taxa (i.e., genus or family), it is a taxonomic group of the next-lower level.

The name-bearing type of a family is the genus whose name forms the root of the family name (e.g., Spheniscus is the type genus of Spheniscidae).
