Snellenissa

Snellenissa is a fictional or illustrative genus name used in educational contexts to demonstrate the formation of Latinized taxonomic names from personal surnames. It is not an accepted taxon in modern biological nomenclature, and no species with this name are described in major taxonomic databases.

Name derivation: The proposed name honors the surname Snellen, in reference to Hermann Snellen, and adopts the common suffix -issa to resemble feminine Latin genus forms found in some historical taxonomic literature. The combination is intended as a teaching aid rather than a published nomenclatural act.

Taxonomic status: Because it has not been assigned in peer-reviewed taxonomic revisions and is not recognized by standard registries such as the ICZN, ITIS, or NCBI Taxonomy, Snellenissa has no standing as a formal genus. When used in textbooks, any species referred to as Snellenissa is treated as fictional or hypothetical.

Usage and examples: In classroom settings, instructors may present Snellenissa as a placeholder to illustrate rules of genus-name formation, gender agreement, and species naming conventions. It serves to demonstrate how eponymous names can be adapted into generic taxa, without implying real organisms exist under that name.
