Review of the Late Jurassic erymoid lobsters (Crustacea: Decapoda)

Erymoid lobsters (Crustacea, Decapoda, Erymoidea) are an important component of Mesozoic crustacean faunas in Europe, especially during the Jurassic. With 36 species reported, these reach their highest diversity Late After review presented here, 23 belonging to ErymaMeyer, 1840 (11 species), PalaeastacusBell, 1850 (2 PustulinaQuenstedt, 1857 species) and StenodactylinaBeurlen, 1928 (8 remain valid. One new is described: Stenodactylina shotoverigiganti n. sp., Eryma pseudoventrosaBeurlen, integrated Stenodactylina. We also notice oldest representative EnoploclytiaM'Coy, 1849, known by a single specimen unidentified at specific level. ventrosum (Meyer, 1835) most common Western may be seen as emblematic Middle-Late Moreover, lithographic limestones Germany yield exceptionally diversified erymoid fauna, with four genera (Eryma, Palaeastacus, Pustulina, Stenodactylina) 11 listed. All Jurassic representatives Palaeastacus were found this lithology. Finally, examination some specimens allows observation strong effects decortication on ornamentation erymoids resulting taxonomic issues.
