Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. Hoffstetter and M. Soria 1986 | Didolodontidae a little smaller than D. multicuspis, half less than M. molariformis. Molar and premolar brachyodonts and bunodonts. P3P4 more elongated than in these two species; Highly advanced P4 molarization; A little less in P3, which is remarkably narrow and long; Paraconide present on P3 P4. M1-M3 without paraconide, but with a short preprotocristide: independent entoconide; No mesoconide, but a "cristida" obliqua as with Ernestokokenia. Dimensions (mm). - Length x width ant. (Trigonide) x post width. (Talonide): P3 8.2 x 4.2 x 4.5: P4b 7.5 x 5.2 x 5.6; M1 6.5 x 5.4 x 5.8; M, 7.5 x 6.2 x 6.5; M3 8.0 x 6.0 x 5.6. Length P3-M1 = 41.7. | |
| A. McGrath et al. 2020 | Brachydont proterotheriid smaller than all other
Neogene proterotheriids. Mesostyle absent in P3–4 unlike Lambdaconus lacerum, Lambdaconus suinus, Paramacrauchenia scamnata, Picturotherium migueli, and Proterotherium cervioides Ameghino, 1883. Hypocone absent in P3–4 unlike Protero. cervioides. P3–M3 with strong interstylar folds as in Lambdaconus spp. Ameghino, 1897, Paramacrauchenia spp. P3 with a continuous cingulum around the lingual edge of the tooth. P4 with distal cingulum that turns mesially and joins protocone. M1–3 with labial cingula. M1– 3 with mesiolingual cingula that join the base of the protocone unlike Param. scamnata and Pi. migueli. M1–2 with metaconule and hypocone subequal to protocone in size unlike Lambdaconus suinus, Paramacrauchenia spp., Pi. migueli, and Protero. cervioides. M1–2 with metaconule not connected to protocone or hypocone unlike Param. scamnata, Pi. migueli, and Protero. cervioides. M3 with a small hypocone connected to the protocone by a crest and an isolated metaconule unlike Lambdaconus suinus, Param. scamnata, and Pi. migueli. M3 with smaller paraconule and stronger mesiolingual cingulum than Lambdaconus inaequifacies and Pi. migueli. Entoconid absent in p3. Paraconid absent in p4– m3, and paralophid terminates at or labial to the labiolingual midline of the tooth unlike Paramacrauchenia spp. p4–m3 with strong labial cingulids unlike Lambdaconus lacerum, Lambdaconus suinus, Param. scamnata, and Pi. migueli. Entoconid of m1–2 larger than hypoconulid. Sulci separating the hypoconid, hypoconulid, and entoconid on m3 unlike Lambdaconus suinus. |
