[Taxacom] Now 2 species/genera in Placozoa...

Sure they "can be" placed in distinct genera. I was just suggesting that genera (or higher Linnean ranks) are not really, in my opinion, suitable as proxies for "distinctiveness". They are just ways to break down complexity into convenient monophyletic groups, but with just two species, there is no complexity. Anyway [Big sigh!], the paper appears to be published e-only without ZooBank preregistration, so the new names don't exist anyway!!

 Hi
 Stephen,
 From my (limited)
 comprehension of the molecular data, the 2 presently
 described species are just representatives of 2 very
 distinct molecular groupings, see diagram at http://journals.plos.org/plosbiology/article/figure?id=10.1371/journal.pbio.2005359.g003
 On a purely hypothetical basis, I do
 not see why a newly described species could not be placed in
 its own genus or any other desired higher taxon (even
 kingdom), if that is used as a proxy for its claimed
 morphological or genetic distinctiveness.

 don't agree with putting the new species in a new genus!
 Genera cannot be correlated consistently with degree or
 "depth" of divergence, and really only serve to
 separate convenient monophyletic groups, but there is no
 gain in separating two species into two separate genera.

  In case anypne interested missed it, there
 
  are now 2 described
 
  species/genera in Placozoa, doubling
 
  the size of that curious phylum:

  They still all look the same,
 
  apparently, but that's another issue.
