Answer the following question: Information: - Borophagina is a hypocarnivorous subtribe of Borophaginae, a group of terrestrial canines which inhabited most of North America during the Hemingfordian stage of the Early Miocene subepoch to the Zanclean stage of the Pliocene epoch 20.63.6 Mya existing approximately . - The subfamily Borophaginae is an extinct group of canids called "bone-crushing dogs" that were endemic to North America during the Oligocene to Pliocene and lived roughly 362.5 million years ago and existing for about . - Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the Cretaceous period, about 99 million years ago and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists. - A clade (from , "klados", "branch") is a group of organisms that consists of a common ancestor and all its lineal descendants, and represents a single "branch" on the "tree of life". - Cynarctina is an extinct hypocarnivorous canine sub-tribe clade of Borophaginae ( bear - dog ) . Cynarctina lived during the Hemingfordian stage of Early Miocene through Clarendonian stage of the Middle Miocene 20.6 -- 10.3 Ma , existing for approximately 4.3 million years . - The Serravallian is in the geologic timescale an age or a stage in the middle Miocene epoch/series, that spans the time between 13.65 0.05 Ma and 11.608 0.005 Ma (million years ago). The Serravallian follows the Langhian and is followed by the Tortonian. - The Langhian is, in the ICS geologic timescale, an age or stage in the middle Miocene epoch/series. It spans the time between 15.97 0.05 Ma and 13.65 0.05 Ma (million years ago) during the Middle Miocene. - The Middle Miocene is a sub-epoch of the Miocene Epoch made up of two stages: the Langhian and Serravallian stages. The Middle Miocene is preceded by the Early Miocene. - In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". What is the relationship between 'cynarctina' and 'subtribe'?
Answer:
