%X A new parvicursorine alvarezsauroid theropod specimen IVPP V20341 from the Upper Cretaceous Wulansuhai Formation of Bayan Mandahu, Inner Mongolia, China is described. IVPP V20341 appears to be distinguishable amongst alvarezsauroids by cervical proceoly and relatively larger semi-circular neural canals, but these features are not proposed as autapomorphies because current knowledge of alvarezsauroid necks and tails remains sparse. IVPP V20341 is distinguishable from Linhenykus - the sole parvicursorine at Bayan Mandahu - by 13 anatomical features that mostly relate to cervical and caudal vertebrae. However, it is unclear how these vertebral elements compare positionally along the spine, so more complete future finds could revise the observed differences. Thus, there are still seven parvicursorine species from the Cretaceous Gobi Basin after the discovery of IVPP V20341.
