A partial skeleton of the ornithomimid dinosaur, 
discovered from the Late Cretaceous Qiupa Formation of 
Luanchuan County, Tantou Basin, Henan Province, China, is 
described here and assigned to a new genus and species, 
Qiupalong henanensis, with unique features (a notch on 
the lateral surface of the lateral posterior process of 
the proximal end of tibia and a small pit at the contact 
between astragalus and calcaneum). A phylogenetic 
analysis in this study suggests that it is a derived 
ornithomimid and form a monophyly with North American 
ornithomimids (Struthiomimus altus and Ornithomimus 
edmontonicus), sharing two characters (straight pubic 
shaft and large acute angle between pubic shaft and 
boot). Some characters (small anterior process of the 
pubic boot and curved pedal unguals) are seen in basal 
ornithomimosaurs as well, but these features in Qiupalong 
henanensis are reversal. Qiupalong is the first 
definitive ornithomimid from outside of the Gobi Desert 
and is the southern-most occurrence of Late Cretaceous 
ornithomimid from eastern Asia, demonstrating southern 
extension of ornithomimid distribution in Asia.
