DIAGNOSIS. — Diaphorocetus ortegai n. sp. is a small- to medium-sized physeteroid (BZW c. 500 mm) differing from Diaphorocetus poucheti by the following cranial characters: smaller cranial dimensions; higher number of alveoli per length unit along the alveolar groove (5.2-5.4/ 100 mm), most likely resulting in a higher tooth count (>18 per upper toothrow); right premaxillary foramen located posterior to the level of the antorbital notch; and absence of a large dorsal infraorbital foramen in the posterodorsal region of the right maxilla, nearly in line with the nuchal crest. HOLOTYPE. — MUSM 3246, a partly complete cranium lacking the distal tip of the rostrum, lateral portions of the neurocranium (including ... : Published as part of Lambert, Olivier, Collareta, Alberto, Benites-Palomino, Aldo, Merella, Marco, Muizon, Christian de, Bennion, Rebecca, Urbina, Mario & Bianucci, Giovanni, 2023, A new platyrostrine sperm whale from the Early Miocene of the southeastern Pacific (East Pisco Basin, Peru) supports affinities with the southwestern Atlantic cetacean fauna, pp. 659-679 in Geodiversitas 45 (22) on pages 663-672, DOI: 10.5252/geodiversitas2023v45a22, http://zenodo.org/record/10228752 ...
