You misspelled it and it is two words, not one.
Scientific naming is called "binomial" naming meaning that there are always two names, 1) the genus which is always capitalized and the 2) species which is never capitalized. If we had the ability here I would have either underlined or italicized it, also always done. Only one or the other not both.
