:It is normal for species to be listed as in Alligator gar, with abbreviated genuses in the  template.  

 :What I noted about families (Blaberidae,Blattellidae) treated as if they were species was my mistake:  these are incorrect taxoboxes that should not use either  or . Since I am currently converting/fixing taxoboxes for all bird species, a daunting task if I ever performed one, I am less than inclined to work on these, but I am sure there are plenty folks at WP:TOL and it's subprojects (which you might want to alert to the problem) to help in this.
