classified as a member of the Nyctosauridae by the original describers because of the two edentulous pterosaurs they possessed good descriptions of, Pteranodon and Nyctosaurus, Zhejiangopterus more resembled the latter. At the time of the description, there was a lack of data on Quetzalcoatlus. In 1997 David Unwin determined that Zhejiangopterus was more closely related to this giant American form and thus belonged to Azhdarchidae. No other azhdarchid is known from such complete skeletal material. Below is a cladogram showing the phylogenetic placement of Zhejiangopterus within the clade Neoazhdarchia. The cladogram is based on a topology recovered by Brian Andres and Timothy Myers in 2013.
