Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. Wang et al. 2014 | An enantiornithine because it has autapomorphies of this clade, as follows: proximal profile of humerus concave, cranial facies immediately distal to head concave, deltopectoral crest narrower than shaft width, and ventral side of distal humerus extending more distally than dorsal side. A small species, with humerus less than half as long as that of Longipteryx, distinguished from other known enantiornithine birds by the following combination of characters: metatarsals II and IV terminate proximal to the entire trochlea of metatarsal III; the trochlea of metatarsal II broader than those of other metatarsals (widely distributed in enantiornithines, e.g., Eoenantiornis, Vescornis); and ungual of digit IV reduced (among other enantiornithines, found only in Vescornis and Qiliania). |
