Universal rules of Binomial nomenclature:-

• Scientific names are in Latin or Latinised and written in italics.
• When handwritten, they are underlined separately.
• The first word is the genus name (Generic name), and the second word is the species name (specific epithet).
  E.g. Homo sapiens: Homo represents the genus name, and sapiens represents the species name.
• The genus name starts with a capital letter, and the species name starts with a small letter.
• The name of the author (in abbreviated form) appears at the end of the biological name.
  E.g., Mangifera indica Linn. It indicates that this species was first described by Linnaeus.
