Infraorder Astacidea // Family Astacidae
  Genus Pontastacus Bott, 1950 Comparison
Representatives of the genus are morphologically very variable, which gave rise to the description of local morphs as separate species. As a result, the species assignment of crayfish is thoroughly confused, and at present 9 species are referred to this genus (WoRMS, 2017), which not so long ago were attributed to the genus Astacus :
Pontastacus cubanicus (Birstein & Vinogradov, 1934)
Pontastacus danubialis Brodsky, 1981
Pontastacus daucinus Brodsky, 1981
Pontastacus eichwaldi (Bott, 1950)
Pontastacus kessleri (Schimkewitsch, 1886)
  Pontastacus leptodactylus (Eschscholtz, 1823)
Pontastacus pachypus (Rathke, 1837)
Pontastacus pylzowi (Skorikov, 1907)
Pontastacus salinus (von Nordmann, 1842)
