What is "hepsetus"

Hepsetus is a genus of African fishes, the African pikes, in the order Characiformes. It is the sole genus in the family Hepsetidae. It was long believed that only a single widespread species existed, H. odoe, but studies in 2011-2013 have shown that this species is restricted to parts of West and Middle Africa. The well-known species of southern Africa, including Kafue River, is Hepsetus cuvieri. These predatory fish reach up to in length.
