Dehalococcoidetes
Dehalococcoides is a class of Chloroflexi, a phylum of Bacteria. It is also known as the DHC group.
The name Dehalococcoidetes is a placeholder name given by Hugenholtz and Stackebrandt, 2004, after Dehalococcoides ethenogenes, a partially described species in 1997, whereas the first species fully described belonging to this class was Dehalogenimonas lykanthroporepellens by Moe et al. 2009, but no emendations to the name were made.
