---|---|---|
R. H. Tedford et al. 2009 | Distinguished from Xenocyon lycaonoides, the only other species of the genus to occur in North America, by slightly larger size, m1 talonid wider relative to trigonid; hypoconid more marginal on the talonid; and M1 metaconule more salient than in most X. lycaonoides. |
