Genus Ihlengesi Bianucci, Lambert, and Post, 2007
Type species: Ihlengesi saldanhae Bianucci, Lambert, and Post, 2007 , by original designation; from the sea floor off Saldanha Bay , South Africa; age unknown.
Species included: Type species and Ihlengesi changoensis sp. nov.
Emended diagnosis.— Ihlengesi differs from all other Hyperoodontinae for the following unique combination of characters: 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 foramen 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 without 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 nares; 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.
