There have been 2 major competing taxonomic schemes for this genus in the late 20th century.

In this taxonomic scheme, moths belong to the suborder Heterocera.

Other taxonomic schemes have been proposed, but none of them is perfect.

Some taxonomic schemes recognize it, others do not, and individual taxonomists are free to use it if they so choose.

The word is also used as a count noun: a taxonomy, or taxonomic scheme, is a particular classification.

Each of them would go on to produce their own taxonomic schemes, though Cronquist's would prove to be the most widely adopted.

The phylogeny of the Acari is still disputed and several taxonomic schemes have been proposed for their classification.

In earlier taxonomic schemes it was known as Acanthophthalmus.

Most of the academic literature provides a basic framework for primate taxonomy, usually including several potential taxonomic schemes.

The most critical point is that different taxonomic schemes should not be mixed in one context.
