vanhenevia

Vanhenevia is a fictional genus created for instructional demonstrations of biological nomenclature and for use in speculative fiction. There is no corresponding fossil record, published description, or recognized specimen linked to this name in peer‑reviewed science. The term has circulated primarily in teaching materials and fan projects as a placeholder taxon used to illustrate how a genus name might be formed and how a species within it would be diagnosed.

Because vanhenevia is not a real taxon, there is no established type species, holotype, locality, age, or diagnostic features. In fictional contexts, authors may freely assign imagined characteristics, but such descriptions do not meet the criteria required for formal scientific naming, diagnosis, or acceptance by taxonomic databases such as the Index Fungorum, ZooBank, or the ICZN.

Usage notes: If you encounter vanhenevia in online content, treat it as a fictional or hypothetical name unless a peer‑reviewed source provides a formal description. The name is sometimes used to discuss concepts like etymology, priority, and the requirements for valid publication in taxonomy.
