Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. Lu et al. 2015 | A large rhamphorhynchine pterosaur with a wing span about 1.1 meters, bearing the following
unique combination of characters: ratio of wing metacarpal to humerus 0.38 (it is smaller than those in other basal pterosaurs); the ulna shorter than each wing phalanx (similar to basal pterosaurs such as Preondactylus and Dimorphodontidae, but it is reversed condition in Scaphognathus); the ulna shorter than tibia (ratio of ulna to tibia 0.92; it is greater than 1 in other rhamphorhynchine pterosaurs); tibia nearly equal to femur in length; length ratio of pteroid to humerus 0.21. |
