T5likevirus [SEP] parent taxon
T5likevirus
T5likevirus (synonyms "T5-like phages", "T5-like viruses") is a genus of viruses in the order Caudovirales, in the family Siphoviridae. Bacteria serve as the natural host, with transmission achieved through passive diffusion. There are currently eight species in this genus, including the type species "Enterobacteria phage T5".

Structure.
T5likeviruses are nonenveloped, with a head and tail. The head is icosahedral (T=13) and is about 90 nm in diameter.
Taxon in disguise
In bacteriology, a taxon in disguise is a species, genus or higher unit of biological classification whose evolutionary history reveals has evolved from another unit of similar or lower rank, making the parent unit paraphyletic. This happens when rapid evolution makes a new species appear radically different from the ancestral group, so that it is not (initially) recognised as belonging to the parent phylogenetic group, leaving the latter an evolutionary grade.
While the term is from bacteriology, parallel examples are found throughout the tree of
