(SDSM 82103)--Wang's (5) diagnosis for the subfamily is based on cranial characters and dental characters of P4, M1, and m1 which cannot be used to determine the identification of the tooth and "the subfamily is mainly defined by its lack of synapomorphics for the other two subfamilies." The lack of the paraconule and metaconule suggest a primitive morphology and support the assignment to the Hesperocyoninae.

The tooth can be described as follows: ectoloph is typically W-shaped; hypocone is absent but a postprotocrista extends posteriad from the metaconule as a curved sloping ridge with a small talon formed by its base.
