Although the species in the genus Metanephrops were previously included in Nephrops, molecular phylogenetics suggests that the two genera are not sister taxa, Nephrops being more closely related to Homarus than either is to Metanephrops.

Most of the fossil species assigned to the genus Nephrops are known only from partial remains, and their affinities are not certain. They include:

  • Nephrops reedi Carter, 1898 – Pliocene, England
  • Nephrops costatus Rathbun, 1918 – Pleistocene, Panama
  • Nephrops maoensis Rathbun, 1920 – Oligocene or Miocene, Dominican Republic
  • Nephrops aequus Rathbun, 1920 – Oligocene or Miocene, Dominican Republic
  • Nephrops shastensis Rathbun, 1929 – Cretaceous, California (possibly belongs in Hoploparia)
  • Nephrops americanus Rathbun, 1935 – Cretaceous, Texas (not similar to Nephrops or Metanephrops)
