Phlaocyonini † is a hypocarnivorous clade or tribe of Borophaginae. This is an extinct group of canids that were endemic to North America and which lived during the Oligocene epoch (Whitneyan stage) to the Miocene (Early Barstovian) living ~33.3–5.3 Ma, existing for approximately . 〔(PaleoBiology Database: Phlaocyonini )〕 Phlaocyonini The clade includes ''Cynarctoides'' and ''Phlaocyon''. These two genus members represent differing approaches of hypocarnivory. The ''Cynarctoides'' trend toward having molar teeth with crowns formed of crescent-shaped cusps and remain small in size. ''Phlaocyon'' specialize toward rounded cusps on the molar teeth but of increasing size, with an unusual trend toward being hypercarnivores by two terminal species in the clade. Four transitional species of ''Cormocyon'' and ''Desmocyon'' occupy intermediate positions between the ''Phlaocyonini'' and ''Cynarctina''. These represent a gradual size increase toward medium-size individuals.〔(Phylogenetic systematics of the Borophaginae (Carnivora, Canidae).
