Indivirus
Indivirus (IndV) is a genus of giant double-stranded DNA-containing viruses (NCLDV). This genus was detected during the analysis of metagenome samples of bottom sediments of reservoirs at the wastewater treatment plant in Klosterneuburg, Austria. New "Klosneuvirus" (KNV), "Hokovirus" and "Catovirus" genera (all found in these sewage waters) were also described together with "Indivirus", building up a putative virus subfamily "Klosneuvirinae" (Klosneuviruses) with KNV as type genus. "Indivirus" has a genome of 0.86 million base pairs (660 gene families). This is the smallest genome among Klosneuviruses as mentioned above. GC content is 26.6 % Classification of metagenome, made by  analyzing 18S rRNA indicate that their hosts are relate to the simple Cercozoa. Phylogenetic tree topology of "Mimiviridae" is still under discussion. Some authors (CNS 2018) like to put Klosneuviruses together with "Cafeteria roenbergensis virus" (CroV) and "Bodo saltans virus" (BsV) into a tentative subfamily called "Aquavirinae". Another proposal is to put them all together with Mimiviruses into a subfamily "Megavirinae".
