Duxeratis

Duxeratis is a fictional genus name commonly used in educational materials to demonstrate the structure and rules of taxonomic nomenclature. It does not correspond to any described taxon in major biological databases, and there is no formal circumscription, diagnosis, or type specimen published under this name.

In teaching contexts, duxeratis is often paired with an example species epithet to form a full binomial, such as Duxeratis nocturnus, to illustrate how species names reflect descriptive traits or locality. The designation helps learners practice publication requirements, holotypes, and the handling of synonyms and homonyms in nomenclatural work, without implying the existence of a real organism.

Because the term is widely used as a pedagogical placeholder rather than as an accepted taxon, it can be applied across different imaginary groups (plants, animals, or microbes) in various textbooks. When encountered outside a classroom, authors typically clarify that the name is hypothetical.
