| Reference | Diagnosis | |
|---|---|---|
| F. Y. Mao and J. Meng 2019 | Among known euharamiyidans, Qishou jizantang is most similar to Shenshou lui (represented by the holotype LDNHMF2001), sharing the features outlined in the family diagnosis. Qishou jizantang differs from S. lui in having the upper incisor with a curved mesial surface (Fig. 1B), somewhat procumbent position and three cusps (Fig. 1D); upper molars more spindleshaped, with cusp A1 being more distally extended and the mesial end of the central valley at the mesial-most point (Figs 3A, B, 4); upper and lower molars bearing more cusps on both the lingual and labial cusp rows; row-b cusps of lower molars aligning mesially with a1 (not mesially extended); m2 longer than m1; functional cusp denoted as AA1(C1) on the labial side of P4 (P3 and P4 unknown in S. lui; Figs 3A, B, 4B). |
