Diagnosis
ReferenceDiagnosis
B. Mennecart et al. 2021Chiyoumeryx nov. gen. flavimperatoris nov. sp. shows the above-mentioned characteristics of the
genus. Chiyoumeryx nov. gen. flavimperatoris nov. sp. is smaller than Chiyoumeryx nov. gen. shinaoensis and
?Chiyoumeryx nov. gen. turgaicus. The p4 of Chiyoumeryx nov. gen. flavimperatoris nov. sp. differs from Chi-
youmeryx nov. gen. shinaoensis by an oblique anterior conid, which is labio-lingually oriented in the larger spe-
cies. A very short posterolingual conid is located between the posterolabial cristid and the transverse cristid in
the p4 of Chiyoumeryx nov. gen. flavimperatoris nov. sp., while it is absent on Chiyoumeryx nov. gen. shinaoensis.
In Chiyoumeryx nov. gen. flavimperatoris nov. sp., there is a tiny anterior cingulid, while it is absent in Chiyoumeryx nov. gen. shinaoensis.
