guineensis

Guineensis is a Latin-derived species epithet used in the scientific names of numerous organisms to denote origin from Guinea, a region of West Africa. In zoological and botanical nomenclature, guineensis is not a taxon or a rank by itself; it is part of a binomial name (genus and species) or trinomial name used to describe a particular species or subspecies. The epithet reflects geographic association—often the locality where the type specimen was collected or where the species was first described—and it may refer to the historic Guinean region rather than to present-day political boundaries.

The term is widely employed across many biological groups, including plants, animals, and microbes. Because the genus name governs the gender of the epithet, the form of guineensis can vary to harmonize with the Latin grammar of the full species name. For example, it appears in diverse genera such as those in plants, birds, insects, and mammals.

Geographic epithets like guineensis are common in taxonomy and are often useful for indicating provenance, but they do not reliably indicate the current distribution of a species. Modern taxonomic work may revise range boundaries or reclassify taxa, so the name should be interpreted primarily as a historical and descriptive label rather than a precise geographic map.

In summary, guineensis is a widespread geographic epithet used to signal a connection to Guinea in West Africa within the scientific names of many organisms.
