Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. M. Schlaikjer 1935 | Orbit incompletely closed. Tympanic bullae relatively small. Molars brachyodont, relatively small and without mesostyles, except a faint indication of one on M3. Postcranial skeleton, as indicated by the pelvis, probably proportionately small and of light construction. | |
| D. R. Prothero 1996 | Stenomyline camels with highly reduced premolars and elongate rostra. Differs from Pseudolabis in these two features and in the lack of a pseudolabine flexure on P4 lingual selene. Differs from the Stenomylini in having lower-crowned teeth; P l / l - C l / 1 diastemata still present; and no diastemata between P2/2 and P3/3. Differs from all other camels in having high-crowned teeth with very weak or no mesostyles, and dorsal premaxilla extended posterior to the level of PL Size quite variable. P2-M3 length ranges from 65 to 84 mm. |
