It's true there aren't any recognized flightless stem-bats, but what do you 
mean by "enormous range"? Archonta is dead, including the "flying primate" 
hypothesis, and the sister-group relationship of Chiroptera and Zooamata 
(Ferae + Perissodactyla) is supported by molecular data, including LINE 
insertion sites. Have I missed something?
