new combination (noun, pl. new combinations;nomenclature term) – a new binominal created by the transfer of a species from one genus into another; also see species name. New combinations are a necessary change in the Linnaean nomenclature resulting from new evidence in interpreting phylogenetic relationships. Apart from name changes caused by the principle of priority, new combinations are the most common nomenclatural changes violating the general goal to establish a stable system of classification. New combinations are a direct result of the binominal, a naming convention deemed superfluous by some authors, but strongly defended by others.
