New bacterial phylum?

So The Scientist wonders:

“It’s always difficult to claim absolutely a new lineage until you’ve done some biochemical tests,” said microbial ecologist Jack Gilbert of Argonne National Laboratory and the University of Chicago, who was not involved with the study, “but, genomics-wise, this thing appears to fit outside of our current understanding.”

Genomic analyses place Kryptonia in the Bacteroidetes superphylum, whose members thrive in the gut and in marine environments. If confirmed, Kryptonia would be the first extreme thermophile found in this group. Kryptonia appears to have acquired this characteristic through horizontal gene transfer from Archaea.
