Diagnosis
ReferenceDiagnosis
R. Pei et al. 2022Papiliovenator neimengguensis can be distinguished from all other troodontids by a unique combination of the following features: lateral groove of the dentary not posteriorly expanded, deep surangular fossa hosting the surangular foramen anteroventral to the glenoid fossa, ventral ridge of the surangular fossa mainly on surangular, anterolaterally broadened and butterfly-shaped neural arches of the first and second dorsal vertebrae in dorsal view.
Among the troodontids from the Wulansuhai Formation at Bayan Manduhu, Papiliovenator neimengguensis can be additionally differentiated from Linhevenator in the presence of unserrated teeth and the proportionally longer humeri (humerus more than half the length of the skull in BNMNH-PV030). Papiliovenator neimengguensis can be differentiated from Philovenator in having a less mediolaterally compressed metatarsus and the mid-shaft of metatarsal II significantly narrower mediolaterally than metatarsal IV in anterior view.
