In biological taxonomy, a species nova (plural: species novae; abbreviation: sp. nov. plural abbreviation: spp. nov.) is a new species.[2] The phrase is Latin,[2] and is used after a binomial name that is being published for the first time.[3] The equivalent for a new genus name is genus novum, and familia nova for a biological family.
An example is the species of miniature frog, Paedophryne amauensis, originally described as Paedophryne amauensis sp. nov. in PLOS ONE in 2012.[1]
The term should not be confused with combinatio nova, used when a previously named taxon is moved to a different genus or species, or its rank is changed.
