Other species
  • †Stichopterus gracilis (Rohon, 1890)
  • †Stichopterus popovi Jakovlev, 1986[1]
  • †Stichopterus reissi Jakovlev, 1977

The type species, Stichopterus woodwardi, was named and described in 1909. Since then, up to three other species have been named or were reallocated to Stichopterus, respectively.[3]

Stichopterus is similar to Peipiaosteus from China. Both genera belong to the family Peipiaosteidae, together with Liaosteus, Spherosteus, and Yanosteus.[3][4] Peipiaosteidae are extinct relatives of Modern sturgeons and paddlefishes (Acipenseroidei).
