Italicize family, genus, species, and variety or subspecies. Begin family and genus with a capital letter. Kingdom, phylum, class, order, and suborder begin with a capital letter but are not italicized. If a generic plural for an organism exists (see Dorlandâs), it is neither capitalized nor italicized.inary genus-species combinations are always used in the singular.
