Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| W. W. Dalquest 1986 (Agriotherium coffeyi) | Simiilar to Agriotherium schneideri but lower P3 a two-rooted tooth rather than absent. | |
| Q. Jiangzuo et al. 2023 (Huracan coffeyi) | Differs from H. schneideri in having slightly larger dental size; narrower M2 with proportionally longer talon; p4 with less distinct anterior accessory cusp and weaker medial ridge; m1 with stronger mesoconid and larger posterior entoconid; m2 with stronger metaconid and better subdivided entoconid. Differs from Huracan qiui in having more reduced P4 anterior hypocone, shorter M1 and M2. | |
| Q. Jiangzuo et al. 2023 | Differs from Huracan coffeyi in H. schneideri by having smaller size, wider M2 with proportionally shorter talon, p4 with weaker anterior accessory cusp and stronger medial ridge, m1 with weaker mesoconid and smaller posterior entoconid, m2 with weaker and more posteriorly located metaconid and poorly subdivided entoconid; differs from Huracan qiui in H. schneideri by having distinctly shorter M1 and M2. |
