Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. Bianucci et al. 2023 | Ihlengesi differs from all other Hype- roodontinae for the following unique combination of char- acters: narrow rostrum in dorsal view; presence of a distinct maxillary tubercle and a wide and shallow prominental notch anteromedial to the antorbital notch; dorsal infraorbital fo- ramen close to the prominental notch at the rostrum base; premaxillary foramen distinctly posterior to the antorbital notch; roughly flat dorsal surface of the preorbital area with- out distinct maxillary crest; moderate elevation of the vertex (less than in the other hyperoodontines but Khoikhoicetus); ascending process of the premaxilla in lateral view concave with posterodorsal portion partly overhanging the bony na- res; transverse distance between the lateral margins of the premaxillary crests less than in the other hyperoodontines; wide space between the premaxillary crests (greater than in Mesoplodon and Hyperoodon); inclusion of the nasal into the premaxillary crest with the at least the left nasal covering about half the length of the median margin of the crest; deep anteromedian excavation of the nasals. |
