Genus Bathynomus A. Milne-Edwards, 1879

Type species: Bathynomus giganteus A. Milne-Edwards, 1879, by monotypy.

Remarks: The single specimen shows the ‘key’ characters for taxonomic attribution to the genus Bathynomus, namely a semicircular pleotelson with sinuous lateral margins and distinct, approximately subequal, spines on its posterior margin, not exceeding the number of 13 (Hyžný et al. 2013). The number and arrangement of pleotelsonic spines together with the shape of uropod rami allow erection of a new species based on the studied fossil specimen.
