#LHT System of Virus Classification
The LHT System of Virus Classification is based on chemical and physical characters like nucleic acid (DNA or RNA), Symmetry (Helical or Icosahedral or Complex), presence of envelope, diameter of capsid, number of capsomers. This classification was approved by the Provisional Committee on Nomenclature of Virus (PNVC) of the International Association of Microbiological Societies in 1962. It is as follows
#Phylum Vira (divided into 2 subphyla)
Subphylum Deoxyvira (DNA viruses)
Class Deoxybinala (dual symmetry)
Order Urovirales
Family Phagoviridae
Class Deoxyhelica (Helical symmetry)
Order Chitovirales
Family Poxviridae
Class Deoxycubica (cubical symmetry)
Order Peplovirales (mantle viruses)
Family Herpesviridae (162 capsomeres)
Order Haplovirales (no envelope)
Family Iridoviridae (812 capsomeres)
Family Adenoviridae (252 capsomeres)
Family Papiloviridae (72 capsomeres)
Family Parvoviridae (32 capsomeres)
Family Microviridae (12 capsomeres)
Subphylum Ribovira (RNA viruses)
Class Ribocubica (cubical symmetry)
Order Togovirales
Family Arboviridae
Order Lymovirales
Family Napoviridae
Family Reoviridae
Class Ribohelica (helical symmetry)
Order Sagovirales
Family Stomataviridae
Family Paramyxoviridae
Family Myxoviridae
Order Rhabdovirales
Suborder Flexiviridales (Plant viruses)
Family Mesoviridae
Family Peptoviridae
Suborder Rigidovirales (Plant viruses)
Family Pachyviridae (20 nm)
Family Protoviridae (15 nm)
Family Dolichoviridae (12-13
