Aagh! He got me!
To be honest, I had to google for it. :-)
Shouldn't that be "Dermatoptera", anyway?
Yes, but I hate the idea of having a taxonomic system that includes a "Euarchonta" without an "Archonta".
I agree. The PhyloCode may even outlaw this in the near future.
I prefer to use "Archonta" for 'primates and their closest relatives' (these days, equals Primates, Scandentia, Derm_o_ptera, Rodentia, and Lagomorpha) and to say that it has been determined that bats are not, in fact, archontans after all.
