The Neuflosser (Neopterygii) are a subclass of the bony fish (Osteichthyes). Of the recent bony fish, they include the seven species of bonefish (Lepisosteidae), the bald pike ( Amia calva ) and the almost 30,000 species of real bonefish (Teleostei). The only recent bony fish that do not belong to the Neopterygii are the coelacanth ( Latimeria ), the lungfish (Dipnoi), the flossler (Cladista) and the sturgeon (Acipenseriformes).

The Neuflosser can be proven fossil up to the lower carbon .


The fin ray carriers (pterygiophores) are equal to the fin rays (Lepidotricha) of the dorsal fin . The suspension of the jaw and the gill cover is done by a new bone, the symplecticum. The hyomandibular, the uppermost bone of the hyoid arch, is connected to the operculare, one of the bones of the gill cover, via a branch. All new flossers lack the acrosome of the sperm .


It is undisputed that the Neuflosser are a monophyletic taxon . There are different views about the family relationships between the basic orders. The bone organoids , long considered a paraphyletic group, have recently been revalidated.
