Strictly speaking, species names are synonymized, not species. (The species is, ostensibly, the actual entity, i.e., the population, and the species name is the label we use to refer to it.) Thus, the number of synonyms doesn't affect your formula. (In practice, people do often use "species" when they mean "species name".) -- T.
