atlanticus

Atlanticus is a genus name used in biological classification. The name has been applied to more than one taxonomic group, resulting in several independent usages that are not all related.

The term derives from Latin Atlanticus, meaning “of the Atlantic,” and it is often chosen for taxa that have some association with the Atlantic regions or oceans, such as the location of the type specimen or notable distribution.

Nomenclatural considerations: Under the codes of nomenclature (the ICZN for animals and the ICN for plants and fungi), each usage is evaluated within its own group. If two genera share the same name within the same code, the later application is illegitimate and must be replaced. The same string, however, can be used in different codes without conflict. Consequently, Atlanticus may be a valid genus in one taxonomic group and a junior or unavailable name in another.

Current usage: Because of its generic nature and the existence of homonyms, the precise identity of Atlanticus depends on the taxonomic group being discussed. Readers should consult authoritative databases or the original descriptions for the exact circumscription and the species included in any particular usage.
