That would be the combination, yes.
The genus "Syntarsus" (or even worse, Syntarsus) should not be used for 
kayentakatae though, as Tykoski and Rowe (2004) have already published the 
combination Megapnosaurus kayentakatae.  Since Syntarsus is a beetle, it's more 
correct to use Megapnosaurus, even in quotation marks.

Also Cryolophosaurus.  My Kayentavenator work should certainly not be published 
without actually checking the material.  Note I didn't actually use any matrix 
to analyze its position, I merely criticized Gay's matrix.  But if somebody 
publishes on Kayentavenator and agrees with my conclusions, I would indeed like 
to be cited.
