Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. Velez-Juarbe 2017 | Small sized pinniped, with an estimated body length of 1.25 m (based on mandible length and toothrow length formulas of Churchill, Clementz & Kohno, 2014). Differing from Eotaria citrica by the following combination of characters: p3–4 and m1 with less trenchant paraconid, p2–4 with smooth lingual cingula, absence of metaconid cusp in the premolars, m2 root rounded, genial tuberosity at the level of p2 (c. 72[0]; shared with the Thalassoleon + Eumetopias clade) and p1 root larger (c. 96[0]; shared with most other pan-otariids).
