Diagnosis
ReferenceDiagnosis
R. H. Tedford et al. 2009Differs from all other species of Leptocyon in being approximately 40% smaller; premolar cusplets and cingular cusps generally weaker and especially weaker than those of contemporaneous taxa; m1 metaconid proportionally larger and taller crowned relative to size and height of protoconid; and m2 lacks a paraconid.
