However, this name had already been used for the snake genus Tomodon Duméril 1853 and Leidy changed it in 1868 to Diplotomodon, adding a Greek διπλόος (diploos), "double", at that time suggesting it was a fish. The type species, Diplotomodon [=Tomodon] horrificus (Leidy, 1865) Leidy 1868 is the only species in the genus that has been described.
