Palaeodromites crypticus , a new early-middle Cenomanian dynomenid crab (Crustacea, Decapoda) from southern Belgium
A single, well-preserved specimen of a new dynomenid crab, Palaeodromites crypticus n. sp., is described from the lower Bernissart Calcirudites Formation (= ‘Tourtia de Tournai’), as formerly exposed at the Delwart quarry, Tournai (southern Belgium). Although superficially similar to contemporaneous P. incertus (BELL, 1863), carapace outline, structure and number of anterolateral teeth and dorsal surface ornament differ to such an extent that introduction of a new taxon appears warranted. The new species probably represents an offshoot of the P. sinuososulcatus-P. incertus lineage, which range... Mehr ...

A single, well-preserved specimen of a new dynomenid crab, Palaeodromites crypticus n. sp., is described from the lower Bernissart Calcirudites Formation (= ‘Tourtia de Tournai’), as formerly exposed at the Delwart quarry, Tournai (southern Belgium). Although superficially similar to contemporaneous P. incertus (BELL, 1863), carapace outline, structure and number of anterolateral teeth and dorsal surface ornament differ to such an extent that introduction of a new taxon appears warranted. The new species probably represents an offshoot of the P. sinuososulcatus-P. incertus lineage, which ranged from the lower Albian (Leymeriella regularis Subzone) to the uppermost Cenomanian (Actinocamax plenus Beds of authors), with records from England, France, eastern Germany and Austria.
