cathayensis

Cathayensis is a Latinized species epithet used in the scientific names of organisms to indicate origin from Cathay, an historical name for China. It is not a taxon by itself; rather, it functions as part of a binomial name that designates the geographic provenance of a species when combined with a genus.

Etymology: The term derives from Cathay, the older Western designation for China, together with the Latin suffix -ensis, meaning “from” or “belonging to.” The form cathayensis is typically written to agree with the gender of the genus it accompanies.

Taxonomic usage: The epithet appears across a range of living and extinct groups in zoological and botanical nomenclature. Because it conveys geographic origin rather than a specific character, cathayensis does not imply a particular evolutionary relationship. The same epithet may be used in different genera for different species described from China, and the correct identification of such species relies on the full binomial name and the associated author citation in taxonomic records.

Notes: Epithets such as cathayensis can be confused with similar geographic terms like sinensis or chinensis, which reflect different historical sources or conventions. When citing or researching a species with the epithet cathayensis, it is important to reference the complete scientific name and the original description to confirm its taxonomic status and provenance.
