The nomenclature of animals using the three terms genus, species and subspecies is called tripartite nomenclature. German scientist Hermann Schlegel (1884) introduced tripartite nomenclature. For example – Khaiya Gokhra (Naja naja naja), Padma Gokhra (Naja naja kauthia), Lice (Pediculus humanus humanus), African lion (Panthera leo leo).
