barnesi

Barnesi is a Latinized species epithet used in biological nomenclature to honor a person with the surname Barnes. In zoological, botanical, and microbial naming, barnesi appears as the second part of a binomial name and is written in lowercase, even when the genus is capitalized. The form is typically derived from the honoree’s name and conforms to Latin grammar and the rules of the relevant nomenclatural code. For a male honoree, barnesi is the common form; for a female honoree, barnesae is typically used, with other forms such as barnesorum sometimes employed to indicate multiple honorees, depending on the taxon and code.

The epithet barnesi is used across various taxonomic groups, including animals, plants, fungi, and bacteria. The choice of epithet rests with the taxonomist describing the species and must be published with a formal description that meets the rules of the respective nomenclatural code. Because the same epithet can appear in different genera, the full binomial name is necessary to uniquely identify a species.
