Taxonomic Levels:
* Genus: A group of closely related species.
* Family: A group of closely related genera.
* Order: A group of closely related families.
* Class: A group of closely related orders.
* Phylum: A group of closely related classes.
* Kingdom: A group of closely related phyla.
Other terms:
* Clade: A group of organisms that share a common ancestor. This term is often used in cladistics, which is a method of classifying organisms based on their evolutionary relationships.
* Taxon: A general term for any group of organisms that is given a formal scientific name.
* Assemblage: A group of species that occur together in a particular habitat or geographic area.
* Guild: A group of species that share a similar ecological role, such as herbivores, carnivores, or insectivores.
Example:
Instead of saying "a subset of species," a zoologist might say "the genus *Panthera*" to refer to the group of species that includes lions, tigers, leopards, and jaguars.
In summary:
The specific term used to describe a subset of species will depend on the context and the nature of the relationship between the species within the subset.
