Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. K. O'Connor et al. 2016 | A small enantiornithine bird with the unique combination of the following features: shallow pneumatic excavations on the lateral surfaces of the thoracic vertebrae; ilium with a very small cuppedicus fossa; robust, curved, weakly retroverted pubis with a dorsally tapered pubic boot; ischium weakly sigmoid with a delicate ridge inferred for muscle attachment on the cranial half of the lateral surface; medial plantar crest well developed on the tarsometatarsus, but lateral plantar crest minimally developed; penultimate pedal phalanges the longest in each digit; non-ungual phalanges of digit II are dorsoplantarly compressed and mediolaterally wide; and pedal unguals large and relatively weakly recurved with long horny sheaths. The species can further be distinguished by its unique tail plumage, which is composed of several different rectricial morphotypes (all other known enantiornithines preserve only a single rectricial morphotype). |
