A new family of Mesozoic Brachyura (Glaessneropsoidea) and reevaluation of Distefania Checchia-Rispoli, 1917 (Homolodromioidea: Goniodromitidae)

Schweitzer, Carrie E.; Feldmann, Rodney M.


Examination of several Jurassic species of brachyurans from Tithonian localities in eastern and central Europe has resulted in one new family, Konidromitidae, two new species, Distefania calva and D. dacia, and numerous new combinations. Palaeodromites A. Milne-Edwards, 1865, is a distinct, monotypic genus within the Goniodromitidae Beurlen, 1932, known from Lower Cretaceous rocks. Distefania Checchia-Rispoli, 1917 (= Cyphonotus Bell, 1863) is recognized as the available name for numerous species, resulting in nine new combinations. Distefania, placed herein within the Goniodromitidae, ranged from the Tithonian to Cenomanian. Many extinct genera previously assigned to Dynomenidae Ortmann, 1892, may not belong to that family.
