Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| I. G. Danilov et al. 2015 | A species of Khunnuchelys which can be differentiated from other species of this genus in that the palatines not only form the lateral walls of the grooves that open posteriorly from the apertura narium interna, but also form part of the floor of these grooves, leaving the grooves less ventrally exposed. In addition, it can be differentiated from K. erinhotensis in that the upper margin of the external nares is located dorsal to the ventral orbit margins, and in that the foramen jugularis posterius is confluent with the fenestra postotica. |
